Switching System
Installation and Operation Summary
This Manual is focused on the needs of the
Installing Contractor and the Operator.
It assumes that the intent of the installation is to:
1 Provide a relay-based switching system for
the lighting
2 Automate the operation of the lighting to
comply with building energy codes such
as ASHRAE 90.1
In the Smartwired Switching System, the
switching platform consists of Relay Panels,
Dataline Switches and a Dataline, which
connects the parts into a small network.
Automatic scheduling functions are provided
by either a plug-in, 8-channel Network Clock
or a Building Management System (BMS)
Interface Module. An optional Photocell
Control Module provides daylighting control
of exterior lighting.
Before starting, read the instructions in this
summary. Full instructions detailing the
installation and operation of Smartwired
Switches, the Network Clock, BMS Interface
Module and other optional automation
devices follow. If you have any questions,
call our Service Team at: 888-852-2778.

Switching System installation and Operation Summary
Installing and Commissioning the Smartwired Switching Platform
Step 1 – Install and Test the Relay
Panels, Dataline and Dataline Switches
Detailed installation instructions for each
of these components is included with the
unit, and is also in the following sections
of this manual.
Two points to remember:
1 Make sure your dataline conforms to
The Watt Stopper specifications (see
above right). If in doubt, use our
dataline wire, HDLW4(P) (plenum
rated).
2 The testing process ensures that all of
the modules are working properly and
that they are communicating with each
other over the dataline.
Step 2 – Number and Document
the Relays and Dataline Switches
This is a key step. It helps clarify your
intent and also provides a simple
reference document for the next step.
As shown in Figure 1 above, relay
panels are numbered sequentially
beginning with 01. Relays within a panel
are numbered from 01 up to 48. By
convention, relay 01-22 refers to panel
01, relay 22. Once you have confirmed
that the relays are connected to the
appropriate loads, record the description
of the load controlled by each relay on
the Smartwired Switching System
Relay Schedule form shown in Figure 2
opposite.
Figure 1 – Smartwired Switching System Platform Installation
The dataline switches for each relay
panel are also numbered sequentially
beginning with 01-01 (panel 01, switch
unit 01). A single switch unit may have
one, two, four or eight buttons. Any
switch button may be “smartwired” to
any group of relays within a single panel.
The relays controlled by each switch
button are recorded on the Smartwired
Switching System Dataline Switch
Documentation form shown in Figure 3
opposite.

Note: To ensure good communications between
panels, the installer must comply with the dataline
specification. The Watt Stopper
®
will not warrant a
system using a dataline that does not meet our
specification. To avoid questions, use HDLW4(P)
(plenum rated). Do not run the dataline in conduit
or wiring trays with power wires. Do not connect
the local datalines from two different panels.

Step 3 – Smartwire the Relays
and Dataline Switches
The actual linking of switches to relays is
simple. It can be done using the process
shown in Figure 4, or by using the
programming function of the Network
Clock (see instructions INHCLK-P). When
the smartwiring is complete, confirm the
operation of every switch button.
With the wallplate removed and the
switch’s master button flipped open …
1 Press the SMARTWIRE tab. The LED
next to the tab will flash once, then the
individual button LEDs will begin to
flash on/off.
2 Press the Switch Button you want to
smartwire (Master Button on an
HDLS1-x). The LED for that button will
continue to flash; LEDs for the other
buttons will stop flashing. LEDs for the
relays currently controlled by that
switch button will also begin to flash.
3 Select the relays to be controlled. In
the relay panel, press the associated
relay control button to add/delete that
relay to/from the group.
4 Press the SMARTWIRE tab again. All
LEDs will stop flashing. The selected
switch button will now control the
selected group of relays.
Test. Press the selected switch button
again to toggle the relay group on/off/
on. Now press each relay control button
to turn each relay off. The switch button
LED will go from red (all relays on) to
green (mixed group) to off when the last
relay in the group is off.

Network Clock
The HCLK8SS Network Clock* provides
scheduling for up to eight global channels
(A-H). Each relay within a panel may be
linked to one of these channels. In
addition, each of these channels may be
assigned any one of four different
automation scenarios:
Scenario 1: Scheduled ON/OFF
(Interior Lighting)
A relay smartwired to a channel assigned
this scenario will turn on whenever the
building is scheduled to be occupied and
turn off when the building is scheduled
to be unoccupied. As an option, the
lights will blink to alert occupants five
minutes before the scheduled off. Any
dataline switch button controlling that
relay will also begin to flash. Pressing the
switch button will stop the flashing and a
timed delay will be applied to the relay,
over-riding the scheduled off.
Data required by the Network Clock:
A Occupancy time by day of week
B Override time (in 10-minute increments,
up to 4 hours)
C Blink warn? Yes/No
Scenario 2: Manual ON/Sched OFF
(Interior Lighting – Alternate)
A relay smartwired to a channel assigned
this scenario will not turn on until turned
on by an occupant. During unoccupied
periods, this scenario acts the same as
Scenario 1 and the same data is required
by the Network Clock.
Scenario 3: Astro (Dark) ON/OFF
(Exterior Lighting – Security)
A relay smartwired to a channel assigned
this scenario will turn on when it is dark
outside and turn off when it is light.
“Dark” is defined by the user as a
number of minutes before or after sunset.
The Network Clock uses an astronomical
* Only one Network Clock can be used per system.
** If a Photocell Control Module (HPCU8SS) is on the system, the Network Clock will request Footcandle data
instead of Location and Dark data. Typical footcandle settings are: Security and Parking – 2 to 20 fc, for
Signage – 20 to 200 fc.
function to determine when sunset and
sunrise occur. It does not compensate for
rainy or overcast days.
Data required by the Network Clock:**
A Building location (nearest city/state or
province)
B Time in minutes before or after sunset
that the lights should turn on (They
will turn off symmetrically relative to
sunrise — example: 30 minutes after
sunset / 30 minutes before sunrise)
Scenario 4: Astro (Dark) ON/Sched OFF
(Exterior Lighting – Parking Lots/Signs)
A relay smartwired to a channel assigned
this scenario will turn on whenever it is
dark outside and the building is occupied.
It will turn off when the building is
scheduled to be unoccupied.
Data required by the Network Clock:**
A Building location (nearest city/state or
province)
B Occupancy time by day of week
C Time in minutes before or after sunset
that the lights should turn on
Step 1 – Define the Global
Channel Scenarios
The Smartwired Switching System
Network Clock Automation Scenarios
form provides a simple method for
documenting the different global lighting
scenarios and the operating data associ-
ated with each. Simply look at the
different lighting loads in the building
and group them by common function.
(Figure 5)
Step 2 – Assign Relays to the
Appropriate Channels
With the above form in hand, it’s easy to
walk through the Smartwired Switching
System Relay Schedule form (Figure 6)
and select and document which channel
a particular relay should follow. (If a
relay doesn’t follow a channel, it won’t
be automated.)
Step 3 – Smartwire Each Relay to its
Associated Channel
Smartwiring a relay to a channel is similar
to smartwiring it to a switch. (Figure 7)
Step 4 – Install the Network Clock
The HCLK8SS simply snaps onto the DIN
rail in any panel and plugs into the
global dataline as shown at right.
Step 5 – Enter the Network Clock
Operating Data
Refer to the Network Clock Installation
Instructions INHCLK-S.
Step 6 – Test the Automatic Operation
Set the Network Clock to two minutes
before a scheduled action and confirm
the operation.

BMS Interface Module
The HBMS8SS Building Management
System Interface Module provides an
intelligent interface to other building
systems, such as HVAC or Security. It is
used instead of the Network Clock
(HCLK8SS) to provide smart control
scenarios for up to 8 global lighting
groups (channels) in the network, and
mounts to any panel’s DIN rail. Only one
BMS Interface Module or one Network
Clock may be used in a system.
Rather than schedule channels, as the
Clock does, the BMS Interface accepts
input from an external system to indicate
the Occupied or Unoccupied status of a
lighting group. For example, in some
retail applications, it may be more
convenient to turn on lighting when the
security system is disabled, just as staff
arrives. From a simple contact closure,
the BMS Interface automatically applies
the proven control scenarios selected for
each channel.
The same scenarios described for the
Clock on page 4 apply to the BMS
Interface Module. However, there are a
few differences between the two units.
Dark scenarios: Because the BMS
Interface Module does not provide
scheduling information, it has no
Astronomical timeclock function. The
“Dark” scenarios for exterior lighting
automatically become available when an
HPCU8SS Photocell Control Module is
connected to the dataline.
Egress Delay: Because the BMS Interface
Module relies on another system for
Occupied/Unoccupied information, it
provides an egress delay. The user can
set a time up to 4 hours after the channel
becomes Unoccupied that allows
occupants to exit the area safely before
the lights are turned off.
Contact Definition: Each channel has
an associated Input Contact and Status
Output Contact. The user can set
parameters for these contacts based on
interface requirements.
Scenario 1: Scheduled ON/OFF
Data required by the BMS Interface
Module:
A Override time delay (in 10-minute
increments, up to 4 hours)
B Blink Warn? Yes/No
C Egress Time (0, 1, 10–240 minute in
10-minute increments)
D Define “Occupied” for Input Contact
(Occupied = Open or Closed contact)
E Define Status Contact (Closed contact =
Any ON, All ON, All OFF, Any OFF)
Scenario 2: Manual ON/Sched OFF
The BMS Interface Module requires the
same data as in Scenario 1.
Scenario 3: Dark ON/OFF
For channels with this scenario, no input
contact is required, since it depends
completely on the exterior light level,
provided by the Photocell Control Module.
Data required by the BMS Interface
Module:
A Define “Dark” for each channel as any
value from 2 to 200 fc.
B Define Status Contact (Closed contact =
Any ON, All ON, All OFF, Any OFF)
Scenario 4: Dark ON/Scheduled OFF
Data required by the BMS Interface Module:
A Egress Time (0, 1, 10–240 minute in
10-minute increments)
B Define “Dark” for each channel as any
value from 2 to 200 fc.
C Define “Occupied” for Input Contact
(Occupied = Open or Closed contact)
D Define Status Contact (Closed contact =
Any ON, All ON, All OFF, Any OFF)
Photocell Control Module
The Photocell Control Module is another
intelligent dataline module for the
Smartwired switching system. It mounts
on the DIN rail in any relay panel, and
connects to the panel’s dataline. A single
photocell (HPSA), mounted on the
building’s roof, provides light level data
to the unit.
The Photocell Control Module compares
the actual outdoor light level with the set
point selected by the user for each of up
to eight (8) channels in the system. It
interacts automatically with either the
HCLK8SS Network Clock, or the HBMS8SS
BMS Interface Module, one of which
must be present in the system.
Set points for each channel are programmed
through the Clock or BMS Interface Module,
which provides scheduling, occupancy
information and the smart scenarios that
tell the relay panels how to respond to a
“Dark” or “Not Dark” signal from the
Photocell Control Module. An automatic
deadband and 5-minute time delay avoid
nuisance switching.
An OPERATE/TEST switch on the unit
makes it easy to simulate light levels for
testing the system setup under different
light level and occupied/unoccupied
conditions. The unit provides quick
visible indication of “Dark” or “Not Dark”
status with bi-color LEDs for each
channel.
