This Wall Switch is intended for installation in accordance with the National
Electrical Code and local regulations. It is recommended that a qualified
electrician perform this installation. Retain these instructions for reference or
download the manual from www.pcslighting.com.
To reduce the risk of overheating and possible damage to other equipment, this
switch is intended for control LED fixtures with Relay Dimming 0-10V receiving
modules installed. This product is for indoor use only. Connect only copper or
copper clad wire to this device.
Important notes prior to installation
1. This wall switch requires a neutral (white) connection wire.
2. Be sure that all power to the load has been disconnected by turning off the
circuit breaker. Installing devices with power on may expose you to
dangerous voltages and may damage the device.

About your WS Wall Switch
The WS Wall Switch (Figure 1) is a high-quality dimmer switch designed to
control LED fixtures with 0-10V drivers connected to RM-0-10V receiving
modules.
About your RWS Remote Wall Switch
The RWS Remote Wall Switch (Figure 2) is a low cost (optional) companion
device to the WS Wall Switch. The RWS has a Decora-style rocker switch that
controls the WS in the same exact way that its local rocker switch does.

Installation Instructions
The Wall Switch is wired directly to the lighting circuit and can optionally be controlled by one
or more RWS Remote Wall Switches producing three, four, or five-way circuits. Multi-way
circuits make it possible for a group of switches to control the same set of lights. This sec t ion
illustrates the connections for the switch, remote switc hes if us ed, and the receiving module.
1. Refer to figures below to determine the wire colors of the hook-up.
2. The WS Wall Switch requires a neutral (white) connection.
3. Remote Wall Switch (optional) requires a connection to AC Line. This wire may be
connected to either phase of the 120/240V supply or any phase or a 3-phase supply.
4. The gray wire on the Remote Wall Switch can be connected to either earth ground or
neutral. The gray wire serves only to light the LED in the remote. This LED does not
indicate anything except that power is applied and to serve as a night-light.
5. If an occupancy sensor is not used, connect the Blue wire must be to line

Figure 6: RM-0-10V Installation in Fixture
Note: The RM-0-10V does not contain an address or other identifying information that t he
transmitter must know to communicate with it. This means that any RM-0-10V can be installed
in any fixture and does not need to be programmed before or after installation.
If the wall switch is dimming more than one LED fixture, install one RM-0-10V in each fixture.
Note: The RM-0-10V does not contain an address or other identifying information
that the transmitter must know to communicate with it. This means that any RM0-10Vcan be installed in any fixture and does not need to be programmed before
or after installation.
If the transmitter powers more than one LED fixture install a RM-0-10V in each
fixture.
Note: When using the wall switch you may hear the relay in the wall switch
clicking very quickly. This “clicking” produces the communication to the RM-010V and is as expected.

Installation Procedure
1. Remove the faceplate from the existing wall switch.
2. Unscrew and pull the existing wall switch out of the wall box.
3. Disconnect the wires from the existing wall switch. Identify the “Line”,
"Neutral", “Load" and “Traveler” wires.
4. Install the WS Wall Switch connecting wiring configuration shown in Fig 3 or
Fig 4.
5. Note the BLUE wire must be connected to LINE if there is no occupancy
sensor used. The BLUE wire provides the power into the relay. The power
then exits to the load through the RED wire.
6. Optionally install any RWS Remote Wall Switch per wiring configuration
shown in Figure 5.
7. After all connections have been made, be certain that all wire connectors are
firmly attached and there is no exposed copper.
8. Gently place the wires and Wall Switch into the wall box, with light emitting
diode (LED) at the top of device, and screw in place.
9. After testing the Wall Switch for proper local operation (per Table 1), install the
faceplate cover(s) to the outside of the Wall Switch(s).

Using Your RWS Remote Wall Switch
The WS Wall Switch can (optionally) be connected to one or more RWS Remote
Wall Switches producing three, four, or five-way lighting circuits. Each Remote
Wall Switch has a Decora-style rocker switch that can be used to control the
lighting load of the WS in the same way as previously described in Table 1.
