Home Automation Digital Switch
PS125
The PS125 is a smart, controllable digital switch, which includes a Light
Sensor and Energy Meter, for your home’s 2-way circuit or 3-way circuit
switch. Together with Controller, PS App (mobile Smartphone /Tablet), and
all PS devices (switches, power plugs, dimmers, and sensors), the PS system
provides you with the capability to control your home’s electrical devices
remotely from anywhere in the world for home automation.
WARINGS AND CAUTIONS
 PS125 is intended to be used as an indoor home switch; it should never
be used for medical and/or life support equipment
 The operation and activation of PS125 can be controlled remotely in a
different place, or by automatic programmed control. As the control
may be intentional or unintentional due to programming, wrong button
pressed, the result of the operation could be undesirable, unexpected,
or even hazardous. Please exercise caution.
 If you are unsure or uncomfortable about performing the installation,
please consult a qualified electrician.

Installation
WARNING
To avoid fire, shock, or death, turn off the power at the electrical service
panel before you install this device.
1. Turn off power to your switch at the electrical service panel
Perform either step 2 or step 3 below
2. Procedure to install PS125 to the 3-way circuit switch (2 switches) :
2.1 There are two switches for the 3-way circuit, please review a typical
wiring diagram below.
2.2 As there are two switches, we need to identify which switch to be
replaced by a PS125 Home Automation Switch. Please follow the
steps below to inspect both switches:
 Remove the receptacle’s cover & the mounting screws.
 Inspect and identify Ground, Neutral, Live, and Load wires in the
receptacle:
2 Load – always present and it is required (black wire)
1 Ground – not always present, but it is optional (green wire)
1 Live – always present and it is required (red or black wire)
1 Neutral – not always present but it is required (white wire). The
Neutral wire is usually present in a screw-on connector.
IMPORTANT :
If the Neutral wire is not present, stop and contact support.
 Turn on power at the electrical service panel and use a “voltage
detector” to test each Live wire of both switches. The switch to be
replaced by PS125 should have the energized Live wire.
 Once the switch to be replaced by PS125 is identified, turn off power
to your switch at the electrical service panel
