A three-way dimmer switch lets you control the brightness of a light from two different locations, such as stairways or large rooms with multiple entrances. It replaces one of the standard switches in a three-way circuit, adding adjustable lighting while maintaining on/off control from both points.
A three-way dimmer switch works within a circuit controlled by two switches. Typically, one switch is replaced by a dimmer switch, allowing you to adjust light brightness at that location, while the other remains a standard on/off three-way switch. Signals travel via traveler wires between switches, coordinating light operation from both places.
There are two main setups:
One dimmer, one standard switch: Only the dimmer can adjust brightness; the other switch toggles the light on/off.
Master/slave multi-location dimmers: Advanced systems use a master dimmer with one or more remote dimmer units, enabling control and dimming from multiple locations.
Ideal applications include:
Stairwells, allowing brightness control at both top and bottom.
Long hallways, for convenience at either end.
Large rooms with multiple entrances, for flexible lighting.
Spaces requiring adjustable mood lighting, like dining rooms or bedrooms.
Three-way dimmers differ physically from single-pole switches by having:
Three terminals: one common (usually darker screw) and two traveler terminals.
No fixed ON/OFF positions; switch position does not always indicate light status.
Always check the switch label and wiring to verify.
Key steps for installation include:
Shut off power at the breaker.
Remove the switch cover and existing switch.
Identify wires: one common and two traveler wires.
Connect ground, traveler, and common wires to the dimmer as per instructions.
Restore power and test full dimming and switching functionality at both locations.
Professional installation is recommended if wiring is unfamiliar or complex.
Use only dimmable bulbs to avoid flickering or damage:
Incandescent
Halogen
Dimmable LED
Avoid non-dimmable CFL or fluorescent bulbs. For Repenic Zigbee Dimmer Switches, ensure bulbs align with compatibility guidelines—incandescent, halogen, and dimmable LEDs are supported, while CFLs and fluorescents are not.
Repenic dimmer switches stand out because they:
Require no neutral wire, easing installation in most UK homes.
Support stable wireless Zigbee communication over 30 meters.
Offer elegant finishes like black metal and brushed brass to match modern decor.
Provide dimmable control for compatible incandescent, halogen, and LED bulbs only.
Do not require smart bulbs or touch features, simplifying usage.
Repenic Zigbee dimmers can be integrated with Apple HomeKit via compatible Zigbee gateways but are not suitable for direct SmartThings connection. They offer reliable wireless control without needing smart bulbs or neutral wire changes.
Safety is paramount:
Always turn off circuit power before installation.
Correctly identify the common wire—critical for proper operation.
Use a licensed electrician if unsure, to prevent shock and equipment damage.
Double-check wiring per manufacturer instructions for Repenic or other brands.

Can I install two dimmer switches for one light?
Yes, advanced master/slave dimmer systems let you dim and control the same light from two dimmers.
Are all bulbs dimmable with a three-way dimmer?
No. Use only dimmable incandescent, halogen, or LED bulbs; avoid CFL and fluorescent bulbs.
Do Repenic dimmers require a neutral wire?
No. Repenic Zigbee dimmer switches are designed for easy installation without a neutral wire.
