AD150
In-Wall Dimmer Module
General Introduction
The In-Wall Dimmer Module is designed to wirelessly control on/off and dimming of light
bulbs. This device is tiny enough to be installed inside an electrical box behind a wall switch.
It also can be connected to the wall switch to allow ordinary manual on/off control. At
220-240V voltage, this module can support up to 300W resistive/ incandescent load, or 200W
fluorescent load.
It supports U-Net two-way wireless technology and is fully compatible with any U-Net enabled
devices. The U-net protocol allows end devices such as AN150 to pair with a U-net gateway
as central control making it suitable for smart home cloud based platforms such as Homesys.
Product Overview
Safety Precautions before Installation
Be sure to isolate or switch off mains power before installing or maintenance.
Avoid installing the unit in stormy or raining weather.
Do ensure that the power supply circuit is protected by a 16 amp circuit breaker or
suitable equivalent fuse.
IMPORTANT
Installation must be performed by skilled technicians who are informed about the standards
and technical requirements of the appliance and its proper installation. Note that the In-Wall
Dimmer Module is designed to be installed in a wall switch box to operate.
Check your local codes as they apply to your situation. If the house wiring is of aluminum,
consult with an electrician about proper wiring methods.
Before proceeding with the installation, TURN OFF THE POWER TO THE LIGHTING
CIRCUIT AT THE CIRCUIT BREAKER OR FUSE BOX TO AVOID ELECTRICAL SHOCK.

Note: By default switch contact S1 supports Single-Pole-Double-Throw (SPDT) type of binary
switch. However, through the setting of Gateway or using the On/Off button, S1 can be
configured to support Tact/Push-button switches as well. Refer to the Operation section.
3. Switch the AC mains power back on to power up the unit.
