See page 2 of this guide for phase-select instructions.

Note: For dimming MLV fixtures, the maximum bulb wattage is typically 70%-85% of the transformer’s VA rating. For actual transformer efficiency, contact the manufacturer. The total VA rating of the transformer(s) shall not exceed the VA rating of the dimmer.

IMPORTANT

CAUTION: Use only with permanently installed fixtures with dimmable screw-in LED, and dimmable self-ballasted compact fluorescent, halogen, or incandescent bulbs. Use only to control the primary side of permanently installed transformer-supplied low-voltage lighting, or in combination with incandescent bulbs. To reduce the risk of overheating and possible damage to other equipment DO NOT use to control receptacles, fluorescent lighting fixtures, non-ballasted or externally ballasted compact fluorescent bulbs, motor-operated appliances, or transformer-supplied appliances.
Neutral is required for all load types.
When no â€œgrounding meansâ exists within the wall box, the NECÂ® 2015, Article 404.9 allows a dimmer without a grounding connection to be installed as a replacement, as long as a plastic, noncombustible wallplate is used. For this type of installation, twist a wire connector onto the green ground wire or remove the green ground wire on the dimmer and use an ap pro pri ate wallplate such as Claro or satin finish series wallplates by Lutron.
Protect the keypad from dust and dirt when painting or spackling the wall.
It is normal for the keypads to feel warm to the touch during operation.
Codes: Install in accordance with all local and national electrical codes. Type 1 action independently mounted operating control. Pollution degree 2, Impulse voltage 4 kV.
Environment: Ambient operating temperature: 32 Â°F to 104 Â°F (0 Â°C to 40 Â°C), 0 to 90% humidity, non-condensing. Indoor use only.
Wallplates: Lutron Claro and satin finish wallplates are strongly recommended for the best color match and clean aesthetic appearance.
Wall boxes: All keypads require a U.S. wall box. 3 in (89 mm) deep is recommended, 2 in (63.5 mm) deep minimum.
RF Device Placement: For reliable performance in a system, this device should be placed within 25 ft (7.6 m) of two additional compatible wireless devices, such as
HomeWorks Sunnata products, Ketra, and the HomeWorks Clear Connect Gateway–Type X. For more information and a full list of compatible wireless devices please refer to the Wireless Setup guide, which can be found in the HomeWorks Support Center link in the Help Section.
System Programming: Programming and activation (addressing) must be accomplished through the HomeWiorks software.
Hybrid keypads are single poles only. For help on adding keypads to 3-way / 4-way lighting circuits, refer to App Note #232 (048232) on www.lutron.com

Wire the control

Mount the wallplate adapter

Mount the keypad and attach the wallplate

Turn the power ON at the circuit breaker

System setup
This keypad must be used in a HomeWorks system with a processor for the control of dimmers, switches, and shades. Use the HomeWorks programming software to set up the system (training is required to access the software).

Operation

Return to factory settings

Note: Returning a keypad to its factory settings will remove the keypad from the system and erase all programming.

Step 1: Triple-tap any button on the keypad (except raise / lower). DO NOT release after the third tap.
Step 2: Keep the button pressed on the third tap until all the status LEDs start to flash slowly (approximately 3 seconds).
Step 3: Immediately release the button and triple-tap the button again. The status LEDs on the keypad will flash quickly. The keypad has now been returned to its factory settings.
