DESCRIPTION

The MSC-100 System Clock provides automated control to

the Watt Stopper/Legrand MRHC3/MRRC3 Scene Interfaces

with Top Dog™ wireless network interconnectivity. The 5-

channel time clock is used with the Watt Stopper/Legrand

wireless network lighting control system, providing on/off

control signals based on time of day, day of week, holiday,

and calculated sunrise/sunset (astronomic time). Simple

programming features combined with advanced control

options make the MSC-100 a powerful tool for automating

your Watt Stopper wireless network system.

Top Dog™ Wireless Communication

Watt Stopper wireless devices use radio signals to

communicate with each other to control lighting and other

types of electric loads in selected areas. These wireless

devices use the 900MHz band for high-speed control

communication. Using the Watt Stopper’s own “frequency-

agile” Top Dog™ technology, these wireless devices avoid

interference with other 900MHz devices, such as cordless

phones and baby monitors.

OPERATION

A hardwired connection from the MSC-100 sends an on/off

signal to relay channels. Schedules within the clock are

programmed events that create on/off commands for clock

channels. Programming is conducted via the easy to read

LCD screen on the MSC-100. All schedules will receive a

number, type, time of day, channel, days to run programs,

and specific event operations. Each schedule can operate on

any combination of regularly scheduled events and holiday

occurrences. All programming is securely stored in non-

volatile memory.

One MSC-100 can support a connection to a maximum of

(2) Watt Stopper/Legrand wireless network Scene Interface

Modules, depending on the number of scenes required.

The MSC-100 has five isolated relay channels. The internal

relay channels correspond to schedule channels 1-5. Spare

relay channels from the MSC-100 can also be used to

control third party devices such as fountains or sprinkler

systems.

Power Failure Memory

After a power failure, all wireless devices automatically

return to the state that they were in immediately prior to loss

of power. All configuration and scene control information is

preserved. The battery backed time carry over assures that

the MSC -100 remains in sync, and the initialization process

within it automatically runs any programming/events that

were scheduled to happen during the power outage.

Application Assistance

The MSC-100 functions as part of a network that contains

Top Dog enabled wireless devices that may

include Miro architectural or decorator-style

in-wall devices as well as portable remote

controls and other accessories. Instructions

for installation, binding operations, and use

are included with the relevant wireless

devices. Application support information

and installation guides for Watt Stopper/

Legrand wireless network devices are

available at www.wattstopper.com.

INSTALLATION

The MSC-100 System Clock can be installed in an equipment

room, garage, or user occupied space and should be located

within a reasonable distance of the house or room scene

controller with which it will be interfacing.

Use low voltage (16-20 gauge Belden or similar) wire to

make all connections between the MSC-100 and the Scene

Interface.

The MSC-100 is an interior device and should not be

mounted outdoors. If mounting in a location that is not

climate controlled, the MSC-100 may be mounted in an

enclosure. However, the wireless devices with which the

clock interfaces cannot be guaranteed to work within a

metallic electrical enclosure.

1. Complete the physical installation and binding of all

wireless devices in the network. Use an appropriate scene

controller or hand held scene remote programmed for

scene set 6-10 to set up the scenes that will be executed

based on the inputs on the MRHC3 or MRRC3 scene

interfaces. See Installation Instructions provided with the

scene interfaces for programming of these devices.

2. Connect wiring between the Scene Interface and the

MSC-100 as shown in the wiring diagram.

2. RELATIONSHIP BETWEEN THE CLOCK AND

THE SCENE INTERFACE

2.1 Interconnectivity

After completing the wiring as described, the MSC-100 can

control (2) separate scenes ON and OFF and a full HOUSE or

ROOM OFF through the use of a single scene interface. This

is accomplished through scenes 6-9 on the Watt Stopper

wireless network system.

2.11 Programming Scenes

A room or house scene should be set up in your Watt

Stopper wireless network system prior to programming

the clock channels. A signal to an MRRC3/MRHC3 Input 1

recalls scenes 6 and 7. A signal to Input 2 recalls scenes

8 and 9. A signal to Input 3 recalls Room On/Off (MRRC3)

or House On/Off or Panic (MRHC3). See the Installation

Instructions for the Scene Interface to program scenes.

2.12 MSC-100 Output

The relay channel outputs on the MSC-100 may be

programmed with an event to turn ON the first scene, or

set of lights, at a given time (set time or astronomic) and

another event to turn OFF the same scene at a second point

in time. Additional relay channels on the MSC-100 may be

used to activate other scenes, to send an OFF signal to the

entire room or house (depending on the scene interface

used), or to enact “panic” mode (see installation instructions

for Scene Interfaces for more detail).

A schedule can be programmed for every day, or individual

schedules may apply to different days. See “Entering and

Editing Clock Schedules” for further detail.

3. PROGRAMMING THE CLOCK

3.1 Function Overview

The MSC-100 has five basic functions which it performs:

• Normal day-of-week scheduled events

• Holiday/exception events

• Override of channels

• Time-keeping

This section provides an overview of these functions.

3.2 Schedule Overview

The day on which scheduled events occur can be on a day of

the week or on a holiday/exception date.

The time of the day which they occur can either be an

explicit time, such as 8:00 a.m., or a calculated time based

on a calculation of sunrise or sunset (astronomical) for

outdoor lighting. Explicit time of day (not an astronomical

time) schedules can be repeated over and over again.

The schedules of the clock create single events which

change state of local relay channels and/or send information

to the scene interface. When an event occurs, it affects the

value or state of a clock channel. So, a single schedule will

turn something ON and OFF.

In many situations, it is desired to turn a load ON or OFF at a

certain time, and then reverse its state later. In those cases,

two schedules are used: one to create an event which will

turn the device ON or OFF, and another to reverse its state.

3.3 Relationship between Schedules and Holiday

Dates

Dates can be defined which change the days on which the

schedule events occur. These dates can have three effects

on the overall schedule of the system:

1) Stop a schedule from occurring on its normal day(s) of

the week;

2) Have schedules occur only on those holiday/exception

dates; and

3) Deﬁ ne when a schedule is to occur in addition to its

normal day(s) of the week.

Each date is assigned to a “holiday type”, H1, H2, or H3.

Each one of these types can be defined in each schedule.

For example, if a schedule is assigned to type HI, then it

will occur on every date(s) which is assigned to H1. See

examples below.

Note: If holiday functionality is not required, skip to

“Entering and Editing Clock Schedules”.

Example One

You will be away for a certain holiday and do not want a

certain scene to function during your absence. These holiday

dates are defined as type H1. For all schedules defined

to use days of the week and NOT H1 will not run on those

dates.

Example Two

You host a yearly party during which time you’d like specific

lights to operate for an extended period of time. These dates

should be assigned as type H2. Schedules for the lights

would be created which define those extended hours and

assigned to H2 and no days of the week. Then, on those

dates, the H2 schedules would run, and the normal day-of-

week schedules would not.

3.4 Entering and Editing Clock Schedules

Schedules are time events saved in non-volatile memory

that cause outputs (clock channels) to turn ON and OFF. The

clock has 120 schedules available. Each schedule consists

of a schedule number, type, time, channel, day(s) and may

also include information for specific clock output channel

operation.

3.41 Accessing the Schedule Screen

To access the schedules from the Run screen, press the

MENU button to access the Main Menu. Then press the UP

or DOWN button to move the Navigation Pointer to “Edit

Schedules” menu items. Press the ENTER button to access

3.44D Time On/Dawn Off (TmOn/Dawn)

The “Time On/Dawn Off” schedule type is used when a clock

channel is to be turned ON at a specific time in the evening

or early morning and then turned OFF when it is dawn.

Dawn is a calculated time that changes with the seasons

according to the geographic location settings entered in the

clock preferences. The Dawn Off event can be offset, plus or

minus, up to two hours from the calculated time of dawn.

If the scheduled ON time is later than the clock calculated

time of dawn plus the offset, the schedule will take no action

and the channel will remain OFF. The scheduled ON time

can only be from midnight (12:00AM or 0:00 hours) to noon

(12:00PM or 12:00 hours) the day of that schedule.

minus 25 minutes (so, if the sunrise occurs at 6:00AM on

that day, the clock will turn channel 1 OFF at 5:35AM). If

the sunrise minus 25 minutes is calculated to occur before

5:00AM, channel 1 will not turn ON that day.

3.44E Dusk On/Time Off (Dusk/TmOf)

The “Dusk On/Time Off” schedule type is used when a clock

channel is turned ON at dusk and OFF at a specified time.

Dusk is a calculated time that changes with the seasons

according to the geographic location settings entered in the

clock preferences. The Dusk ON event can be offset plus or

minus up to two hours from the calculated time of dusk.

If the scheduled OFF time is earlier than the clock

calculated time of dusk plus the offset, the schedule

will take no action and the channel will remain OFF. The

scheduled time OFF can be scheduled from noon the day of

the schedule to noon the next day.

at 6:00PM on that day, the clock will turn channel 1 ON at

6:30PM). If dusk plus 30 minutes is calculated to occur after

8:00PM, channel 1 will not turn ON that day.

3.44F Dusk On/Dawn Off (Dusk/Dawn)

The “Dusk On/Dawn Off” schedule type is used when a clock

channel turns ON at dusk and OFF at dawn. Dusk and dawn

are calculated times that change with the seasons according

to the geographic location settings entered in the clock

preferences. The Dusk On and Dawn Off events can be offset

plus or minus up to two hours from the calculated time of

dusk or dawn. There is no time data associated with this

schedule.

3.5 Time (Time:)

The time parameter of a schedule is the time of day at which

the schedule event occurs. Schedule time is in whole minute

increments displayed in either AM/PM(12 hour) format or

military time (24 hour) format. The time format is selected in

the clock preferences setting (see section 3.7).

Enter the schedule time by navigating the pointer to the

“Time:” descriptor in the Schedule screen and then press

the NEXT button (or, if already in the schedule “Type:” data

field just press the NEXT button). The hour data field will

become active by blinking. Use the UP and DOWN buttons to

change the hour value.

Press the NEXT button to advance to the minutes field and

set the minutes by using the UP and DOWN buttons. Press

the NEXT button to advance to the next schedule parameter.

Execution of schedules is based on time of day and is

subject to the processing time of the clock. This means

that schedules may not actually occur exactly on the time

transition from one minute to the next, but may be delayed

by a few seconds while the clock processes the various

schedules.

The time parameter saved for Time On/Dawn Off is the time

the assigned channel will turn ON. The time parameter

saved for Dusk On/Time Off represents the time the

assigned channel will turn OFF (see Schedule Types section

3.4.4, Time On/Dawn Off & Dusk On/Time Off).

There are no time parameters for Unused schedules or for

the Dusk/Dawn schedule type (see Schedule Types section

3.4.4, Dusk On / Dawn Off).

3.6 Clock Channels (Chnl:)

Clock channels are the physical and software controlled

channels which are affected by schedules. Schedules cannot

exist without assignment to a channel. Channels 1-3 will be

used with a Scene Interface.

Enter the channel by navigating the pointer to the “Chnl:”

descriptor in the Schedule screen and then press the NEXT

button (or, if already in the PREV data field just press the

NEXT button). The channel data field will become active

by blinking. Use the UP and DOWN buttons to change the

channel number.

Press the NEXT button to advance to the next schedule

parameter. A schedule cannot be saved to memory without

3.7 Days of the Week and Holiday types

(Day: SMTWTFS 123)

A schedule may execute on any day of the week/holiday or

multiple combination of days as needed. Schedules which

have holiday types H1(1), H2 (2), or H3 (3) assigned allow

the schedule to execute on dates that are saved with that

holiday type through the EDIT HOLIDAY menu.

When a date that has previously been saved as a holiday

through the EDIT HOLIDAY menu function occurs, all

schedules that would normally operate on that day of week

(Monday, Tuesday, etc.,) do not execute. Instead, only the

schedules assigned to the holiday type (either H1, H2, or H3)

execute on that date and continue to execute on subsequent

days depending on the duration of the holiday saved for that

holiday date (see Entering and Editing Holiday/Exception

Dates, section 3.5).

The days of the week are abbreviated “SMTWTFS” starting

with Sunday ending with Saturday. The three holiday types

are abbreviated “123” corresponding to H1, H2, and H3

holiday types. Select the data fields for the days by using

the NEXT and PREV buttons. The cursor will flash under

the abbreviation for day of the week or holiday type. Use the

UP or DOWN button to select the current day by placing an

asterisk under the abbreviation for the day of the week or

holiday.

Pressing the UP or DOWN button again will de-select the

day. Use the NEXT and PREV buttons to go forward and

backward as needed to select other days of the week for

schedule operation.

A schedule of any type except UNUSED cannot be saved

without at least one day of the week selected.

3.8 Saving Schedules to Memory

At the bottom of the Schedule screen the text “ENTER TO

SAVE” will appear. Whenever this text line is visible on the

clock screen, the clock is prepared to save recently entered

data. Pressing the ENTER button immediately saves the

displayed schedule’s data to non-volatile memory. After

the ENTER button is pressed and the schedule saved, the

display will show the first four lines of the next sequential

schedule number. Schedules recently entered are not

executed until the clock initializes the schedules when it

returns to the Run screen.

If an entry error is made in the schedule data, the clock will

not store this schedule in memory when the ENTER button

is pressed. Instead, the clock will highlight the first data

field of the error to be corrected before the schedule can

be saved to memory. Common errors might be no channel

number entered, or no days entered, etc.

Figure 3.8 shows the last four lines of a schedule that

repeats every hour. Pressing ENTER from this screen will

save this schedule into the clock’s memory.

CAUTION

If new data is entered into a schedule and the schedule

exited without saving, the schedule data will be lost. The

schedule will revert back to the data previously entered

in memory. Example: if data was entered into schedule

1 and then schedule 1 is exited by going to another

schedule number or by returning to a menu screen without

pressing ENTER to save, the new data for schedule 1 will

be lost. Schedule 1 will revert back to previously entered

data in memory. Also, if schedule data is entered into

the clock screens but not saved, after three minutes of

button inactivity, the clock will time out and return to

the Run screen without saving the new schedule data.

4. ENTERING AND EDITING HOLIDAY/

EXCEPTION DATES

Note: If no holiday schedules are necessary, skip to

“Changing Time and Date”.

The clock has advanced holiday/exception (referred to as

holidays) date scheduling ability. The clock can have up to 32

holiday start dates each with a duration of 1 to 120 days in

length. Each holiday may be assigned one of three different

holiday day types, H1, H2 or H3.

When a holiday start date occurs, the clock substitutes the

assigned holiday day types (H1, H2, H3), for the normal day

of the week schedule (Monday, Tuesday, etc.,) which would

normally be executed. Selecting the schedules that execute

on a holiday is done when entering and editing Day-of-

Week Schedules (see section 3.4). The clock can continue to

execute the holiday schedule for a consecutive number of

days specified by the holiday duration.

The holiday worksheets found at the end if this manual

should be filled out prior to entering any holiday data.

for that holiday number. Press the NEXT button to advance

to the next holiday data field.

4.4 Holiday Types (Type:)

Each holiday has a holiday type to determine which clock

schedules will execute on a specific holiday. There are four

holiday types; H1(1), H2 (2), H3 (3), or UNUSED. On the

holiday start date and continuing through the duration of the

holiday, the clock will substitute the schedules assigned to

the holiday type instead of the schedules normally executed

on the day of the week. Holiday types are assigned to

schedules when entering or editing schedules (see Days of

the Week and Holiday Types, section 3.7).

Enter the holiday type by navigating the pointer to the

“Type:” descriptor in the holiday screen and then press the

execute each year perpetually. If selecting a day of week

holiday the year/month data field will scroll the months of

the year (Jan., Feb., etc.). Press the NEXT button to advance

to the next data field.

Holiday dates can be any one of the following type of holiday

events:

4.51 Single Date Holidays

Single date holidays can be any date M/D/Y or D/M/Y in

the future up to the year 2097. These holidays execute

the schedules assigned to the holiday type (H1, H2, H3)

at the beginning of the start date and continue executing

the schedules for the duration of the holiday. Single date

holidays are a one time occurrence and will not execute

again after the date has passed.

4.7 Saving Holidays to Memory

At the bottom of the holiday screen the text “ENTER TO

SAVE” will appear. Whenever this text line is visible on the

clock screen, the clock is prepared to save new data to

memory. Pressing the ENTER button immediately saves the

data for the displayed holiday to non-volatile memory. After

the ENTER button is pressed and the holiday is saved, the

display will show the first four lines of the next sequential

holiday number. Holidays recently entered will not execute

until the clock initializes when it returns to the Run screen.

>ENTER TO SAVE

Figure 4.7 Holiday edit screen Enter To Save selected.

Figure 4.7 shows the last four lines of a holiday that occurs

each year on the last Monday in May and occurs for just one

day. Pressing ENTER from this screen will save this holiday

into the clock’s memory.

If an entry error is made in the holiday screen data, the

clock will not store this holiday in memory when the ENTER

button is pressed. Instead, the clock will highlight the first

data field of the error to be corrected before the holiday can

be saved to memory. Common errors might be no holiday

number of days entered, etc.

CAUTION

If new data is entered into a holiday and the holiday is

exited without saving, the holiday data will be lost. The

holiday reverts back to the data previously entered in

memory. Example: if data was entered into holiday 1 then

holiday 1 is exited by going to another holiday number or

by returning to a menu screen without pressing ENTER

to save, the new data for holiday 1 will be lost. Holiday

1 reverts back to PREV entered data in memory.

Also, if holiday data is entered into the clock

screens but not saved, after three minutes of button

inactivity, the clock will time out and return to the

Run screen without saving the new holiday data.

5. CHANGING THE TIME AND DATE

The clock time and date is supported and kept current

by an internal clock chip. When power is lost to the clock

and clock operations cease, the memory is safely stored

in non-volatile memory and the clock is kept running by a

back-up lithium battery. The lithium battery can support the

clock chip for eight years if the clock were to remain without

power for that period of time. The replacement battery

is a # BR1616 by RayoVAC, Panasonic or other common

manufacturer.

The clock date automatically compensates for leap year

and will also automatically compensate for daylight savings

transition if configured to do so (see Setting Daylight Savings

Time in section 3.7).

The clock can compensate for astronomic seasonal changes

in the sunrise and sunset times throughout the year. By

calculating when dusk and dawn occurs for each day of the

year, exterior lighting and other controlled loads influenced

by the sun may be automatically controlled without the use

of a light level sensor or photocell device. The required

parameters for the clock to accurately calculate dusk and

dawn are position by latitude and longitude and time zone.

Longitude:+122°

Latitude:+38°
