The PCT503 thermostat makes it easier to control your household
temperature and hot water. It is designed to work with the ZigBee gateway
so that you could remotely control the temperature anytime through your
mobile phone. You can schedule your thermostat working hours so it will
work based on your plan.
This guide will provide you with an overview of the product and will help
you understand how to use it.

Warning!
• High voltage! The PCT503 thermostat must be installed and serviced only
by a quali󽗉ed electrical personnel.
• Do not touch the terminals of the device during testing.
• Turn o󽗈 all the power supply for this equipment before installing.
• Make sure that the power supply is o󽗈 before connecting or disconnecting
it to an auxiliary device.
• Always use a properly rated voltage sensing device to con󽗉rm power is
o󽗈.
• Replace all devices, doors and covers before applying power to the
equipment.
Failure to follow these instructions will result in death or serious injury.
You should install the receiver 󽗉rst. The Heat Receiver is necessary and do
not connect the thermostat directly to your heating system,even if there are
low-voltage wires.High voltage current will ruin your thermostat.
Before the installation, please notice:

7
Step 1. Switch o󽗈 the power
Before you get started, please turn off the heating system and the
thermostat . Remember! You are working with mains voltage, so protect
yourself.Adjust the temperature in your old thermostat to double check the
system is o󽗈.
Step 2. Position the Heat Receiver
Use the screws to mount the Heat Receiver near the boiler or junction box.
Note:The Thermostat and Heat Receiver communicate wirelessly within
30 meters. Walls and large objects (boiler, hot water tank, etc.) between
them can a󽗈ect the communication range, and metal objects can block the
signal.Please try to avoid those objects between the Heat Receiver and the
thermostat when installing.

• Connect the L (live) and N (neutral) terminals on the Heat Recevirer to the
L and
N circuit on the boiler or junction box to power the Heat Recevirer.
Connect the heating control circuit to the Heat Recevier 4 (normally open),
5 (common), 6 (normally closed) as needed.
• If your system has a hot water control circuit, connect it to 1 (normally
closed), 2 (common), 3 (normally open) as needed.

3-2 Installing the thermostat
Position the thermostat
The PCT503 Smart Thermostat should be:
• Away from the heat source and in a room that`s used often, so the
thermostat can read the right temperature and the homeowner can easily
use it .
• Communicate wirelessly with Heat Receiver within 30 metres and avoid
blocking the signal mentioned on page 6.
Step 1. Place the stand
Find a desk, shelf or other 󽗊at surface with a socket. Then place the stand
on it.
Step 2. Attach the PCT503 to the stand
Gently press the PCT503 into the stand until it clicks. Then connect the
power cable through the port on the stand to the Micro Usb port on the
back of the thermostat.Plug the power cable into the wall socket.
To place it on a 󽗊at surface,
please use:
