Caution: To reduce the risk of injury and/or overheating and damage to other equipment:
• Make sure that the power at the circuit breaker is turned OFF before starting.
• A neutral (typically white) wire is required.
• Replace single pole switches ONLY. Not compatible with 3-way switches.
• The wire colors indicated in this manual are typically found and may differ in some
• Ensure the wire conductors are securely fastened to each wire.
• It is recommended that a certifi ed electrician completes all high voltage electrical
• Must follow all building and electrical codes in the region when installing.
• Do not install to control an appliance, motor or receptacle.
• Recommended to be installed in a minimum 2.5" depth device box.
• Do not mix different load types or different luminaires on the same dimmer.
• Dimmer does not work with smart bulbs or fi xtures.
• Intended for installation in an in-wall electrical box.
1. Turn OFF the power at the
circuit breaker and confi rm
with the voltage tester at the
switch before proceeding.
Place voltage tester against the
existing switch checking the
wall plate, screws and switch
at various points to determine
that there is no power present.

7. Turn on the power at the circuit breaker.
8. Test to see that the Smart Dimmer is functioning by pressing
the ON/OFF switch. Your load (lights) should turn ON/OFF
Note: If your lights do not turn on, your live and load wires
might be incorrectly connected. Turn off power at the circuit
breaker and try swapping them.
Refer to “WiZ Quick Setup Guide”
Before you start, make sure you install the WiZ App from
either Google Play or the (both offer Apple App Store
the same set of features). The app can also scale to fi t
Note: Upon fi rst boot-up, the fi rmware may need to be updated. Please allow up to 1 minute for the Smart Dimmer to update after completing WiZ app setup.

Installing and pairing smart dimmer
The dimmer switch is connected through the app and will only operate on your home’s 2.4GHz Wi-Fi network. Most
new routers are dual-bandwidth (both 2.4GHz and 5GHz), ensure you select the 2.4GHz network which covers a
wider range than the 5GHz. To make sure your phone is on the 2.4GHz network, either select it in the list of available
networks on your phone or go into the router settings and temporarily de-activate the 5GHz network (you can activate
it again after pairing is done).
If this is not possible and the dimmer switch is not found, try putting the dimmer switch in pairing mode by holding the
ON/OFF button for 5 seconds (or until the indicator lights fl ashes red), then walking a short distance away from the
router. Due to the short range of 5GHz networks, your phone should auto-connect to the 2.4GHz at this point. Once
connected, you can start pairing in the app. You can pair as many devices as you want at the same time.
