1.Horizontal installation
2.Vertical installation
Installation Instructions
a. The thermostat supports both horizontal and vertical installation. However, vertical installation may lead to inaccurate
temperature readings because the built-in temperature sensor is close to the radiator.
c.When the screen displays the number [F1], press the thermostat button 3 times continuously to calibrate the valve. During
calibration, the screen will show the [F2] symbol. ( Note: If [F1] is not displayed, you can try pressing and holding the device
button for 10 seconds to reset the device.)
1. Frost Protection
When the built-in temperature sensor detects a temperature of ≤ 5℃, the device will automatically activate its anti-freeze
protection and initiate heating; when the built-in temperature sensor detects a temperature of > 8° C, the device will turn off
anti-freeze protection and resume normal operation. (The anti-freeze mode in Zigbee is adjustable, with an adjustment
range of 5~15℃. Under the Thread protocol, it is defaulted to 5℃ and cannot be adjusted.)
2. Open Window Detection
Once Window Detection is enabled:
No door/window sensor bound: If the temperature drops by 3 °C within 5 minutes, Heating mode will automatically pause
for 30 minutes.
With a bound door/window sensor: If the sensor detects that a door or window has been open for more than 3 minutes,
Heating mode will automatically pause for 30 minutes.
d.The [F2] symbol will disappear aer approximately 10 seconds, and the screen will display the current set temperature,
indicating that the installation is complete.
Note: Regardless of the installation method, an external Aqara temperature and humidity sensor is recommended to ensure a more precise
temperature control.
b. Align the thermostat interface nut with the radiator valve, and rotate the nut until it is tight.
Note: The installation of the [M30*1.5 mm] valve interface is as shown in the diagram.
Note: You can deactivate the window detection function on the W600 device itself.
3. Schedule
The device will automatically control the heating system according to the preset time period and temperature, allowing
different temperatures to be set for the morning, daytime, evening and night time periods for each day of the week. A single
schedule supports up to 7 time periods, each of which is at least 15 minutes.
4. Manual Control
Turn the heating on or off by manually to adjust the target temperature, or select a comfortable heating temperature by
manually switching presets (if a schedule is created, the device will follow the schedule aer the Hold time ends).
6. Calibration
Supports calibration of built-in temperature and humidity sensors, with an adjustment range of -5~+5℃ and an adjusting
increment of 0.5℃
7. Fully on and fully off the modes
When you rotate the device beyond the minimum temperature adjustment range (continue rotating when the set
temperature is below 5℃), the device valve will be fully closed, and the screen will display OF at this time.
When you rotate beyond the maximum temperature adjustment range (continue rotating when the set temperature is
above 30℃), the device valve will be fully open, and the screen will display ON at this time.
