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 also schedule your thermostat working hours to match your plans.
This guide will provide you with an overview of the product and will help
you understand how to use it.

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 the "C" wire, you can use the power module to power your
thermostat using the existing 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.

1.How to pair the thermostat with Remote Zone Sensors?
1. Click the '+' button at the top right of the interface in 'Menu' -> 'Sensors'
on the thermostat and tap 'Next'.
2. Remove the rear cover of the sensor.
3. Press and hold the button on the back of the sensor for 3 seconds until the
indicator on the front of the sensor ashes red.
4. Wait for sensors to pair automatically. When the pairing is successful, the
sensor ashes green 3 times.
Now you can set the participation period of the sensor. During this period,
the thermostat will take the average temperature of all the sensors that
recently detected motion as the indoor temperature on the main screen.

Please press and hold the
button on the back of the

then tap ‘Next’.
Tip: During sleep time, the sensor enabled during this period doesn't
care about occupancy; it will always participate in the calculation of the
average temperature. When you change the setting of sensor, the indoor
temperature on the main screen will update in 2 minutes.

2. Wi-Fi conguration of the thermostat failed
- Conrm the entered router password is correct.
- Please conrm the network is stable. Put the phone besides your
thermostat and make sure they are in the same network environment. Try
opening a website to judge if the network can be used.
- Conrm adding device is under 2.4G WI-FI channel. If 2.4G and 5G WIFI
use the same name, it is recommended to change to a dierent name.
- Ensure that the DHCP service is enabled for the router. If not, the IP
address will be occupied.
- If it still does not work, it is recommended to change the router and try
again.
3. Device oine
- Conrm that the thermostat is powered on.
- Conrm whether the device or the network has been cut o. If so, Please
check the status 2 minutes later. It may need some time to recover.
- Please conrm whether the home Wi-Fi network is normal, or whether
the Wi-Fi name and password has been modied.
- If the network is normal, but the device is still oine, please check if there
are too many Wi-Fi connections. Please try to restart the router and wait
for 5 minutes, then check the status of the device.
- If there still have problems after the above checking, it is recommended
to remove the device or change the router to add it again.
