The Wi-Fi Touchscreen thermostat makes it easier and smarter to control
your household temperature. With the help of zone sensors, you can
balance hot or cold spots throughout the home to achieve best comfort.
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.

Step 1. Switch o󽗈 your HVAC system
Before you start, please switch off your HVAC system to protect you and
avoid blowing a fuse. Wait a few minutes, try to adjust the temperature in
your old thermostat to double check if the system is o󽗈.

Step 3. Compatibility Check
If you find a thick wire with wire nuts on the backplate of the old
thermostat, or if the voltage of your old system is 120v or higher, it will not
be compatibled with PCT513. If none of the above, then please proceed to
the next step.

Step 5. Label the Wires with Tags
Label each wire on the wallplate with the tags (label 1) provided. Then
carefully disconnect the wires.
Note: If there are any jumper wires between Rh, Rc, or R terminals, do not
label them. PCT513 does not need jumpers. Remove them and save along
with your old thermostat.

Hi,
Welcome

Power module requires your system to have the following wires:
4 wires: W/W1, Y/Y1, G, and R (or Rc or Rh)
or 3 wires: Y/Y1, G, and R (or Rc or Rh)
If you do not have these wires, your system may not be
compatible with the power module.

The C-wire is used to provide power to the thermostat. If your system does
not have "C" wire, you can use the power module to power your thermostat
using the exiting wires.
There are two sides with connections. One side (4 terminals) is for
thermostat connections, the other side, pre-wired (5 terminals), is for the
control board connections.

Step 6. Position the wiring module
The power module should be installed between your thermostat wiring and
your control board. Install it at the right position then close the HVAC cover
panel securely and return to your thermostat.
Step 5. Connect the wires
Generally, the control board will have W, C, G, Y, R terminal, connect the
pre-wired side of the power module (5 terminals) to the corresponding
terminals.
