INTRODUCTION
Welcome to the LP Series Lighting Control Panels
The LP panels contain up to 8 relays controlling lighting through automatic scenarios, time schedules,
photocells and occupant controlled switches. Scheduling capability is included through a built-in clock with a
keypad and display window on the interior. The interior provides isolation between the line- and low-voltage
sections of the panel, as well as the mounting frame for relays, the power supply and the circuit board
assemblies.
LP panels are shipped with all their components installed in a locking enclosure. The LP8’s enclosure is
compact, measuring only 16.5” x 15.1”. The LP24’s enclosure is equipped with din rails to accomodate up
to 12 contactors. A secure outer cover protects the user from the high voltage area. A separate interior
enclosure protects the low voltage wiring and components while allowing easy user access to the time clock
scheduling controls.
Before installing the LP8, read the instructions completely. Most functions are the same for the LP24 as for
the LP8. Throughout this manual, references to LP8 features, functions, programming and wiring also apply
to the LP24, unless specifi ed otherwise. If you have any questions, call our Service Team at: 888-852-2778.
Use the plastic sleeve affi xed to the inside of the enclosure cover to keep these
instructions and the completed system documentation forms for future reference.

Low Voltage Wiring
Open the interior door to access the connectors in the low voltage section. All input/output wiring in this
section must be low voltage, Class 2 wiring. Do not use the low voltage wiring compartment as a raceway or
junction box. Refer to local codes regarding Class 2 wiring practices.
Hardwire Low Voltage Switches (Optional)
LP8 panels include a switch input for each relay. These accept any of the dry-contact confi gurations shown
below. Operation of the switch will turn on/off the corresponding relay.
Do not interconnect multiple relay inputs to each other.
To control multiple relays from a single input device, the optional
Group Switching Card is required. See page 9.

Group Switching and Smartwire Procedure (Optional)
The Group Switching (GS) card provides eight channels (A-H), which may be Smartwired
to relays within the panel. These Group Switching channels are used to group relays
for common control by switches or occupancy sensors. Do not confuse the Group
Switching channels with scheduling channels (discussed in the programming section,
pages 11, 16 and 18 of this manual). Group channels created using the GS card are
intended for use with switches or sensors connected to the card’s inputs. These groups
can be set to exactly or parially match the scheduling channels as required.
Setup
1. On the Group Switching card, press and hold the Group channel push button for
several seconds. The red channel LED and the LEDs for relays currently controlled
by that input will begin to fl ash.
2. On each Relay card, select the relays to be controlled.
If a relay was previously Smartwired to the channel input selected, the LED will be
fl ashing, otherwise the LED will be off. Press the associated Relay Control Button
to add/delete that relay to/from the group. The LED for each relay included in the
group will be fl ashing.
3. On the Group Switching card, press the Group Channel Push-button
again. All LEDs stop fl ashing and the input switch will now control the
relays selected.
Test Smartwired Relay Group Channels
1. Press the Group Channel Push-button ON/OFF/ON to toggle the
group ON/OFF/ON.
2. The input LED will track the last action. Now, with all relays in the
group on, turn off each relay in the group using the individual Relay
Control Buttons. When the last relay is turned off, the channel LED
should also go off.

CONNECT THE LP8 POWER SUPPLY
The LP8 has several power supply options that allow it to operate with 115VAC, 240VAC, 277VAC or 347VAC
line voltage. These power supplies function with either 50 or 60 Hz. They have internal overcurrent protection.
The transformer automatically turns off when overloaded and resets when the fault is removed. The power
supply contains MOVs to protect all downstream electronics from powerline voltage spikes.
1. Read and remove the CAUTION label covering the terminals.
2. Note that there are different terminals for supply voltage input. Wire to ONLY ONE of these terminals.
Match your input voltage to the correct terminal.
Figure 5: P115/277 wiring Figure 6: P115/347 wiring Figure 7: P240 wiring
CONNECT LINE VOLTAGE
Before making any connections to the relays, make sure that none of the load circuits are shorted. Wire from
the circuit breaker through each relay’s SPST output terminals, and from there to the loads. Confi rm that
each circuit is wired to the relay specifi ed in the electrical construction drawings.
Power Up and Test Relays
1. Apply power to the LP8 power supply ONLY.
Do NOT apply power
to the controlled
circuit loads.
2. As shown in the
illustration, press
the Relay Control
Button next to each
relay’s yellow plug-in terminal to toggle it on/off.
The relay should “click” and it’s LED indicator
should change state.
3. Confi rm the operation by measuring the continuity at
the line voltage terminations of each relay.
4. Apply power to the relays.
5. Being careful not to touch any line voltage wiring,
toggle each relay on/off again and confi rm that each
relay controls the appropriate load.
Confi rm Nominal Operation
With power applied to the LP8 panel, there should be
two (2) green LED indicators glowing on the power
supply card in the lower left corner of the panel. And,
there should be six (6) green LED indicators glowing at the
top of the panel below the EM24A2 photocell connector. A
single (1) blue LED in this group blinks approximately once per second indicating normal operation.
Each relay driver card (2 cards for 8 relays) has a blue LED that should fl ash randomly. The group switching
card (optional) also has two (2) blue LEDs that fl ash randomly during normal operation.
If you are having problems with your LP8, please note the condition of all
the LEDs before calling Watt Stopper technical support.

CHANNEL ASSIGNMENT FOR RELAYS
Each relay has a default assignment to a channel as shown below:
Relay # 1 2 3 4 5 6 7 8
Channel A B C D E F G H
Relay assignment can be changed to suit your application. Multiple relays can be assigned to the same
channel allowing a single channel to control multiple relays. In this case, some channels will not have a
relay assigned to them and they will be unused. See “DATA ENTRY — SETUP, Assigning Relays to Channels”
on page 18 for programming instructions.
PRE-PROGRAMMED CONTROL SCENARIOS
Scheduling is simplifi ed through an occupied/unoccupied approach. Lighting events happen based on
whether the area is scheduled to be occupied or unoccupied at any given time. For exterior lighting, ON/OFF
events may also depend on whether or not it is “dark” outside.
Summary of Lighting Control Scenarios
Each channel may be assigned one of the seven scenarios described in the following sections for each day of
the week, plus holidays. Following is a list of the scenarios and the options that are programmable for any
particular day and channel.
Scenario Name Programmable Options
Manual On/Sched Off • Occupied times for each day and holiday
• Blink warning before off (Yes/No)
• Time delay override time (1-240 min)
Scheduled On/Off • Same as above
Man On/AS Sweep Off • Occupied times for each day and holiday
• Sweep interval (1-240 min)
Photocell On/Off • No additional data. Connect #EM24-A2 photocell to LP8 panel.
Photo & Sched On/Off • Occupied times for each day and holiday
• Connect #EM24-A2 photocell to LP8 panel
Astronomic On/Off • SETUP Location (state/province/city or global coordinates and time zone)
• Minutes (0-120) before or after sunset = “dark”
(same # of minutes after or before sunrise = “light”)
Astro & Sched On/Off • Same as Astronomic, plus Occupied times for each day and holiday
The type of scenarios chosen for each channel depend on how the space in the building is used. Questions to
ask when selecting scenarios include:
• Is it an interior or exterior space?
• Should occupants turn lights on when they arrive, or should lights turn on automatically?
• Do occupants need to be warned when lights are about to turn off?
• Should exterior lighting stay on all night, or turn off after the building is closed?
CAUTION
DO NOT USE THE BLINK WARNING FOR OUTPUTS CONTROLLING HID LAMPS,
AIR CONDITIONING, FANS AND OTHER SIMILAR LOADS.
Page 12
Switched and Scheduled Interior Lighting Options
The following pre-programmed control scenarios are commonly used in interior lighting applications. These
scenarios are ideally suited for applications where occupants need manual or other local control options
such as switches, occupancy sensors or other signaling devices, as well as automated functions provided
according to schedules.
Manual ON/Scheduled OFF (Interior Lights)
A channel assigned this scenario does not turn on its relay(s). The relays must be turned on by one of the
switch device options illustrated in the Low Voltage Wiring section of this manual (see Figure 3, page 8).
Relays are automatically turned off at the end of scheduled occupancy.
Lights can be overridden ON beyond the scheduled occupancy time with the programmable override Time
Delay. If a relay is turned on by a device outside of the occupancy time, the relay remains on for the length of
the Time Delay. It is important to program a Time Delay for every day, otherwise relays that are overridden
ON will remain on until manually switched off or until the next scheduled end of occupancy. To ensure that
an override time limit is always active, enter a Time Delay for every day of the week and holiday. For days
when occupancy is not expected, program a schedule with an occupancy time of Open/On 00:00 thru 00:00
and enter a Time Delay of at least 10 minutes.
You can enable a Blink Warning that momentarily turns off the relay, then immediately turns it back on, to
alert occupants 5 minutes before the lights are turned off.
Data required by the Clock:
A Occupancy times by day of week
B Override time delay (in 10-minute increments, up to 240 minutes)
C Blink warn? Yes/No
Scheduled ON/OFF (Interior Lights)
A channel assigned this scenario turns on its assigned relay(s) whenever the building is scheduled to be
occupied. It turns them off when the building is scheduled to be unoccupied. Operation during unoccupied
time periods and Time Delay programming requirements are the same as Manual ON/Scheduled OFF.
Data required by the Clock:
A Occupancy times by day of week
B Override time delay (in 10-minute increments, up to 240 minutes)
C Blink warn? Yes/No
Manual ON/Automatic Switch Sweep OFF (Interior Lights with AS-100 Switch)
In this scenario, lighting is turned on manually using AS-100 Automatic Control switches. During the
scheduled unoccupied times, a Sweep OFF function is active. The Sweep OFF is programmed by entering
a Sweep Interval time (1-240 minutes) for each day. Each time the Sweep OFF triggers, the channel turns
off its relay(s) for one second, then back on. This brief power interruption blinks the lights and signals
each AS switch on the branch circuits to begin a 5-minute delay off countdown. During this countdown,
occupants can press their AS switch to keep the lights on until the next OFF sweep. If the switch button is not
pressed during the 5-minute delay countdown, the switch automatically turns the lights off at the end of the
countdown.
If the area controlled by the channel is normally unoccupied the entire day (e.g., weekends), a schedule with
a Sweep Interval value must be programmed for that day even though there may not be an occupancy time
entered (Open 00:00 thru 00:00). If a Sweep Interval time is not entered, the relay turns off at midnight of
the last scheduled day and the AS-100 switches will not be able to turn the lighting on until midnight of the
following scheduled day.
Data required by the Clock:
A Occupancy times by day of week
B Sweep interval — the time from one OFF sweep to the next (in 10-minute increments, up
to 240 minutes)
Automatic ON/Sweep Switch OFF (Interior Lights with AS-100 Switch)
In this scenario, lighting is turned on automatically by the AS switch. During the scheduled occupied times,
the lighting can be controlled ON/OFF by the occupant using the button on the AS switch.
Photocell Control Options
If an EM24-A2 Photocell is connected to the system, the following exterior lighting scenarios may be used.
Photocell ON/OFF (Exterior Lights — Security)
A channel assigned to this scenario turns on its relay(s) when the photocell signals it is dark outside. It turns
off the relay(s) when the photocell signals it is light.
No additional data is required by the clock.
Photocell and Schedule ON/OFF (Exterior Lights)
A channel assigned this scenario turns on its relay(s) when the building is scheduled to be occupied and
the photocell signals that it is dark outside. It turns off the relay(s) either when the building is scheduled
unoccupied or when the photocell signals it is light.
Data required by the clock:
A Occupancy times by day of week.
Astronomic Control Options
Using the LP8’s built-in timeclock, the Astronomic functions automatically calculate sunrise and sunset
times according to the panel’s location as programmed in SETUP — Select Location.
Astronomic ON/OFF (Exterior Lights — Security)
A channel assigned this scenario turns on its assigned relay(s) when it is dark outside and turns them off
when it is light. “Dark” is defi ned by the user as a number of minutes before or after sunset. The sunrise
darkness threshold mirrors the sunset programming, meaning that if you set dark for 20 minutes BEFORE
sunset, the morning light begins 20 minutes AFTER sunrise. No compensation is made for rainy or overcast
days.
Data required by the Clock:
A Building location (nearest city/state/
province or geographic coordinates,
entered in SETUP screen)
B Time before or after sunset that the
lights should turn on (in 10-minute
increments, up to 120 minutes). The
lights will turn off the number of
minutes before or after sunset and
the same number of minutes after
or before sunrise – example: 30
minutes after sunset / 30 minutes
before sunrise (see Figure 9).
Astronomic & Scheduled ON/OFF (Exterior Lights)
A channel assigned this scenario turns on its relay(s)
when it is dark outside and the building is occupied. It will turn off when the building is scheduled to be
unoccupied. Generally, lights turn on in the evening, off at night when the building is not occupied, then back
on in the early morning until it becomes light.
Data required by the Clock:
A Building location (nearest city/state or province, entered in SETUP screen)
B Occupancy times by day of week
C Time in minutes before or after sunset that the lights should turn on

Sample Scenario Application
For the sample application used in the Data Entry Setup and Programming sections that follow, an offi ce
building is used. In this application, the LP8 panel contains two relays controlling open offi ce space lighting.
Two relays control hallways and common area lighting. Another relay controls the branch circuits to
individual offi ce lighting, with Automatic Control Switches in those offi ces. There is also a relay for exterior
security lighting and two for parking lot lighting and signage.
The sample Programming Record Sheet on the next page summarizes the data required by the Clock for
each channel in our sample application.
Channel A is assigned a Manual ON/Scheduled OFF scenario for the open offi ce areas. The lights will
be turned ON by occupants using a switch. They can be turned off by the occupant using a switch or
automatically per the time schedule. Overrides will be in effect if the occupant manually turns lighting on at
the switch during unoccupied times.
Channel B is assigned a Scheduled ON/Scheduled OFF scenario for corridors and common areas. The
lighting turns on and off per the times scheduled. Overrides will be in effect if the occupant manually turns
lighting on at a switch during unoccupied times.
Channel C is assigned a Manual ON/Automatic Switch Sweep OFF scenario for multiple private offi ces.
Occupants use the AS-100 switch to turn on the lights in their offi ces. During unoccupied times, the LP8
panel periodically blinks the lights, starting a 5-minute delay off countdown at the AS-100 switches. If
no occupant overrides it, the AS switch will turn off the lights. The sweep off scenario is repeated at the
programmed sweep interval until the scheduled occupied time.
Channel D is assigned an Astro ON/OFF scenario for exterior security lighting. The on and off times are
based on the clock’s astronomical function which determines sunrise and sunset according to geographical
location. Note: A similar operation can be achieved by connecting an exterior photocell to the LP8 and
programming a Photocell On/Off scenario.
Channel E is assigned an Astro and Scheduled ON/OFF scenario for parking lot lighting and exterior building
lights. The time this lighting turns on is based on the clock’s astronomical function as above, but the lights
will turn off at a scheduled time. The lights will turn back on in the early morning if it is scheduled to turn on
and the astronomical function determines that it is still dark. Note: A similar operation can be achieved by
connecting an exterior photocell to the LP8 and programming a Photo & Sched On/Off scenario.

3. Program Holidays
Holiday scheduling allows the LP8 to operate different schedules on
specifi c dates. This is to accommodate different scheduling for holidays
and special occasions. When a programmed holiday date occurs, instead
of executing the schedules according to the day of the week the LP8 will
execute schedules that are assigned to Holiday in the schedule program
screen. (See Data Entry — PROGRAM, Scheduling)
Access the holiday setup screen from the SETUP Menu. Use the arrow
keys to highlight “Program Holidays” and press the SELECT key. The
Program Holidays option brings up a listing of twelve individual holiday
or vacation date entries (Figure S4). Make each date entry in MM/DD/YY
format.
If you need to enter more dates, SAVE the current page when you have
fi lled all 12 holiday entries. This returns the display to the SETUP menu.
Navigate back to the Holiday page. You will see the fi rst 12 holiday dates
you entered. Use the arrow keys to highlight the arrow ( -> )in the lower
right corner of the screen. Press SELECT. There are three screens of
twelve entries each for a total of 36 holiday date entries. Remember to
SAVE each screen when you complete data entry on it.
When a holiday spans several consecutive days, you can enter a date
range. Highlight RANGE and press SELECT. A screen of six range entries
appears (Figure S5). Enter the fi rst date of the holiday range and then
the date the normal schedule resumes. When all holiday date ranges are
entered, highlight SAVE and press SELECT. This will return you to the
Main screen.
4. Location Entry
Setting up the correct geographic location is important to using the
astronomical function. You can enter the location using one of two
methods. You can select the closest city to the panel’s location from a list
of States, Provinces, Countries and Cities, or you can manually enter the
global coordinates. To manually enter the coordinates, you must know
the latitude, longitude, and hours ahead or behind GMT (Greenwich Mean
Time) for the panel’s location.
Select the Location Setup screen from the SETUP Menu.
To enter location by city, use the arrow keys to highlight the State data
fi eld and use the RAISE or LOWER key to select the state, country or
province. States of the USA are listed fi rst in alphabetical order (using
the RAISE key), followed by countries, then Canadian provinces and
territories. After selecting the correct State, country or province, use the
arrow keys to highlight the City data fi eld and use the RAISE or LOWER
keys to select the city closest to your location. The geographic coordinates
and GMT Offset fi ll in automatically based on the State/City you’ve
selected.
To enter a location manually, highlight the State fi eld and use the RAISE
or LOWER key to fi nd Alabama, the fi rst State listed alphabetically. Press
LOWER once to bring up *Manual Entry* then press SELECT. Highlight the
Latitude fi eld. Press RAISE or LOWER until the correct degrees Latitude
appears in the numeric fi eld. Highlight the letter fi eld to select either N or
S (for North or South of the equator). Press SELECT. Repeat the process
for the Longitude fi eld, making either an E or W selection for East or West
of the prime meridian.
When the Coordinates are completely entered, use the down arrow
(6) to move to the Hours data fi eld. The words “Ahead of” or “Behind”
will be highlighted. Use the RAISE or LOWER key to select whether the
panel’s time zone is Ahead of or Behind GMT. Then, highlight the numeric
fi eld and use RAISE or LOWER to enter the number of hours difference
between the panel location and GMT. Example: The U.S. Eastern time
zone is Behind 06 hours from GMT (Behind 05 hours during Daylight
Savings Time).
When the location data has been entered, highlight SAVE and press
SELECT to return to the main screen.

5. Assigning Relays to Channels
To simplify program scheduling, the LP8 has 8 relays which may be
assigned to one of eight channels A-H. To change this setting from factory
default, go to the Setup Menu, use the up or down arrow keys (56) to
highlight “Assign Relays/Channel” and press the SELECT key. This brings
up the Relay Assignment screen.
Use the RAISE or LOWER keys to select a channel for each relay. Move
between channel data fi elds by using the Left or Right arrow keys. A
relay may only be assigned to one channel, but multiple relays may be
assigned to the same channel. Following this assignment, relays will be
automatically controlled through program scheduling by the assigned
channel.
When the relay to channel assignments have been entered, navigate to
SAVE and press SELECT to return to the main menu or ABORT to cancel
the assignment setting and return to the main menu.
Clearing the Memory
The last menu item on the SETUP screen is “Clear All Memory.” This
function is used to clear all memory in the LP8 clock and reset data to
factory defaults. The clock’s fi rmware version appears below this item on
the SETUP screen.
If you want to clear the Clock’s memory and re-enter all programming and
setup data, select Clear All Memory. When the “You are about to Clear all
Memory” screen appears, you can retain the stored data and return to the
main menu by pressing the SELECT key while ABORT is highlighted
— or — highlight CLEAR and press SELECT to clear memory.
If you select CLEAR, a confi rmation screen appears as shown in Figure
S11.
System Setup is now complete. Proceed to the DATA ENTRY -
PROGRAM section on page 19 to begin scheduling channel scenarios.

DATA ENTRY PROGRAM
Scheduling
Before you begin channel programming, it is important to complete the
Programming Record Sheet for your installation. Scheduling is simply
taking the data from the Programming Record Sheet and entering it into
the Clock. Once that’s been done and all Setup steps are completed, the
clock has all of the data necessary to control the lighting system.
To illustrate the data entry process, we will use the data from our Sample
Application.
Begin with the Main Screen showing in the clock display (Figure P1). You
can return to the Main Screen at any time by selecting SAVE or ABORT on
any data screen and pressing SELECT. Highlight PROGRAM at the bottom
of the screen. Press SELECT to advance to the Channel program screen
(Figure P2).
Manual ON/Scheduled Off — Channel A
Referring to the Sample Programming Record Sheet on page 15, we see
that Channel A is to be assigned a Manual On/Scheduled Off scenario. The
form shows that the general offi ce area is occupied on weekdays from 7:00
a.m. through 6:00 p.m., and on Saturday from 7:00 a.m. until noon. A limit
of 120 minutes on override time delays during unoccupied periods and a
“blink warn” before the scheduled Off is required.
Figure P2 shows the default Channel A program screen for Monday.
Select the channel by highlighting the Channel data fi eld and use the
RAISE or LOWER key to display the desired channel (A for this example).
Highlight the Day data fi eld and use the RAISE or LOWER key to select the
desired day (Monday for this example).
Highlight the scenario selection data fi eld and use the RAISE or LOWER
key to select the scenario (“Man ON/Sched OFF” for this example).
Highlight each time fi eld and use the RAISE and LOWER keys to enter
the time that the area is “open” or “occupied.” Remember to use 24 hour
military time units.
Note: You may enter two sets of times, but this is not typically required. For
example, if selected lighting is turned off at lunchtime, a typical schedule
might be:
Open: 07:00 thru 12:00
Open: 13:00 thru 18:00
After entering time data in each fi eld, highlight the next fi eld, or simply
press SELECT to automatically go to the next fi eld.
Enter the override Time Delay (in 10-minute increments, up to 240
minutes). This is the amount of time the channel will remain ON when
turned ON by a device outside of scheduled occupied hours. For the
example this is set to 120 minutes.
Highlight the “Blink before off?” data fi eld and select Yes to program the
channel to blink the lighting fi ve minutes prior to shutting off.
Finally, set Blink before off? to Yes.
At this point there are three choices:
1. SAVE this information to memory: the schedule data for only Monday
would be saved.
2. COPY this data to other days of the week and then save the schedules
for all of these days. Performing a COPY saves a lot of time because the
same schedule occurs each weekday and a modifi ed version occurs on
Saturday, Sunday and Holidays. Highlight COPY and press SELECT. See
“Copying a Schedule” on the next page to continue programming.
3. ABORT to exit without saving any data.

Copying a Schedule
To copy a schedule to other days, you must start from the COPY function
on the screen showing the schedule that you want to copy. After you
highlight COPY and press SELECT, the schedule is automatically saved and
the Copy Program to: screen appears.
Highlight a day for which you want the schedule copied and press the
RAISE or LOWER key to enter an “X” in the box. Repeat for each day that
the schedule should run.
To save the schedules for the days marked with an “X”, highlight SAVE and
press SELECT.
For our example application, to complete programming Channel A, you
need to schedule Saturday, Sunday, and Holidays. You can COPY the
Monday schedule to Sat, Sun and Hol, then edit each day for the different
occupancy times.
To edit the schedules that were copied to Saturday, Sunday and Holiday, go
to the Channel A PROGRAM screen and highlight Monday. Use the RAISE or
LOWER key to change to Saturday then press SELECT. Notice that the data
fi eld entries are the same as Monday’s. Use the Down Arrow to move to the
occupancy time fi elds that need to be changed. Use the RAISE or LOWER
key to enter the new times. Highlight SAVE and press SELECT. Repeat this
process for each day that needs to be edited.
In our sample application, Sundays and Holidays do not have an occupied
schedule, therefore, make all time entries 00:00. Enter an override time
delay and blink warning, for those occupants who may come in to work on
these days. (Note: You may use a completely different schedule including
a different scenario for different days of the week. For example, a longer
override delay time may be preferred on weekends.)
Scheduled ON/OFF — Channel B
Channel B on our sample Programming Record Sheet is assigned a
Scheduled On/Off scenario for corridors and common areas. Lights in
these areas turn on at 6:00 a.m. and turn off at 10:00 p.m.
From the main screen, go to the channel program screen by highlighting
PROGRAM and press the SELECT key. Select the channel by using the
RAISE or LOWER key to display the desired channel (B for this example).
Highlight the Day data fi eld and use the RAISE or LOWER key to select the
desired day (Monday for this example). Highlight the scenario selection
data fi eld and use the RAISE or LOWER key to view scenario choices (select
“Scheduled On/Off” for this example) Figure P7.
Highlight each time fi eld and use the RAISE and LOWER keys to enter the
time the channel should turn the lighting On and Off. In the example this
would be 06:00 (6:00AM) and 22:00 (10:00PM).
Note: You may enter two sets of times, but this is not typically required. For
example, in some applications, selected lighting is turned off at lunchtime,
requiring two ON/OFF schedules. Another example would be an application
which requires an ON/OFF period to start on one day and extend past
midnight to the next day. This is called “time spanning” and is explained in
its own section of this manual.
Set the override Time Delay at 120 minutes and the Blink before off? to
Yes. Figure P7 shows the complete data entry for this scenario.
As with the Channel A example, use the COPY function to create schedules
for Tuesday through Friday. Saturday has a different occupancy time
and Sunday and Holidays use a Manual On/Sched Off scenario and are
scheduled to be unoccupied all day (all occupancy time values are 00:00).
Use the COPY function to copy the Sunday schedule to Hol (Figures P8 and
P9).
