Wiring Diagram
The diagram illustrates the connections for NO, COM, and NC terminals. It notes that for passive linkage of wall-mounted furnaces, the COM and NO ports are used. A crucial note advises that due to the strong power design of some circuits in this product, installation must be performed by professionals.
Connections:
- NO (Normally Open)
- COM (Common)
- NC (Normally Closed)
The diagram shows a connection from the Boiler to these terminals.

Low-Temperature Protection Function
The thermostat is in the off state. When the indoor temperature drops below 5 degrees Celsius, the thermostat will automatically turn on the heating function. When the indoor temperature rises to 7 degrees Celsius, the thermostat will automatically turn off the heating.
Installation Steps
1. Gently pry open the device display panel using a screwdriver.
2. Install expansion screw sleeves with a spacing of 59mm on the wall. Place the backplate in the installation position, insert, and tighten the screws.
3. Re-attach the panel to complete the installation.
Inspection Steps
The intelligent touch screen thermostat should be installed in a location where users can easily view the screen and adjust the temperature setting point. Position the thermostat in a location that represents the overall ambient temperature of the room. Avoid installing the temperature controller near cold and heat sources, such as ventilation openings, heaters, outdoors, or places exposed to direct sunlight.
Common Fault Handling
| Phenomenon | Processing Method |
|---|---|
| Not turning on | 1. Check if the battery is installed backwards. 2. Check if the power button is valid. |
| Display garbled characters | Is the installation of the rear shell deformed? It can be loosened and reinstalled. |
| Normal display without output | 1. Check if the wiring between the main control board and the power board is damaged. 2. Check if the output is wired incorrectly. |
| Temperature display error | Calibrate panel temperature display through the first option of advanced options. |
