Installation
Mains and Zone Wiring
Verify Wiring
- Follow the steps below to verify there are no faults in the load or wiring.
- Turn off power. DO NOT WIRE LIVE.
- With the 5-position bypass jumper installed in the terminal blocks, the wire loads to the DH terminal blocks as shown.
- Apply power and ensure that the desired loads power on without any faults.
Zone Wiring
- Turn off the power. DO NOT WIRE LIVE.
- Wire mains and loads to the module as shown.
- Remove the 5-position bypass jumper from Hot and Load terminals.
- Apply power. See section 5 to verify zone wiring.
QS Link
- Turn off power while servicing the module. DO NOT WIRE LIVE.
- Wire QS link to the module as shown, note terminals 3 and 4 are twisted, screened pair. Recommended Lutron cable: GRX-CBL-346S for wiring length less than 500 ft (153 m); GRX-CBL-46L for wiring length up to 2000 ft (610 m).
- The link may be daisy-chained or t-tapped.
- Do not connect to terminal 2.
Note: See “HomeWorks QS Wiring Guidelines” application note on www.myLutron.com
Contact Closure Input / Output
Turn off power while servicing the module and wire CCI / CCO as shown. DO NOT WIRE LIVE.
- CCI If not needed, leave pre-installed jumper in CCI terminals.
- Input is Normally Closed. If Contact Closure is opened, the module will go to Emergency light levels and will not respond to inputs from other devices.
- CCO When using a room thermostat or 3rd party contactor for a receptacle control, normally open or normally closed dry contacts must be used.
- The CCO is not rated to control unclamped, inductive loads. Inductive loads include, but are not limited to, relays, solenoids, and motors. To control these types of equipment, a flyback diode (not included) must be used (DC voltages only). See diagram.
- Accepts voltages of 0 –24 V~ / 0 –24 V-; see chart below for load switching capacities:
- Switching Voltage Resistive Load R
- 0 –24 V- 1.0 A
- 0 –24 V~ 0.5 A

Zone 1-4 LEDs start scrolling| No QS Link communication or no communication
with the processor
Programming
Note: For programming: use the programming software suite.
Manual Mode O era ion
- To turn ALL loads on the module On or Off
- Press the “Prog” button to toggle lights On or Off.
- To turn individual loads On or Off
- Press the respective zone button (e.g., “Zn.1”).
FAQ (Frequently Asked Question)
- Can I switch receptacles with this product? No, only lighting and motor loads can be switched.
