Safety Precautions
To ensure your safety and avoid damage to the device, please read the safety precautions.
- ⚠️ WARNING: Please trust the distributor or a professional installer to install the device.
- Installation by non-professionals may result in improper installation, electric shock, or fire.
- Adhere to this installation manual.
- Improper installation may lead to electric shock or fire.
- Reinstallation or changes must be performed by professionals.
- Do not uninstall or make changes to the device randomly.
- Random changes may lead to abnormal operation, heating, or fire of the HVAC system, and causing damage to the smart thermostat.
- ❗ REMINDERS:
- Do not install the device in a place vulnerable to leakage of flammable gases. Once flammable gases are leaked and left around the smart thermostat, fire may occur.
- Do not operate the device with wet hands. The presence of liquids may cause electric shock or damage the device.
- Always disconnect the device from the power source before installation or maintenance to avoid equipment damage or potential electrical shock.
- The wiring should be rated for the thermostat current. Ensure that the power supply for the smart thermostat is securely isolated when connecting a non-communicating HVAC system.
- Ensure the connected cables meet CL2 requirements and meet National and local electrical standards. Otherwise, electric leakage or heating may occur.
- Do not alter terminals of this device.
- Before drilling through the wall, ensure that there are no electrical wires, water pipes, or gas pipes inside the wall.
- Please install the power supply unit according to the instructions in this manual. Do not alter the power supply unit or use non-specified power supply products.
- During installation and use of the thermostat, please prevent liquid (water, alcohol, etc.) from entering the device.
Select the Installation Location
- Do not install the device in a place vulnerable to leakage of flammable gases. Once flammable gases are leaked and left around the thermostat, fire may occur.
- Do not install in a place where heavy oil, vapor, corrosive, or sulfureted gases are present. The device could be damaged, leading to system malfunction.
- Do not install on an exterior wall.
- Install the thermostat on a flat wall. An uneven wall may lead to an unstable installation.
- Do not install near any heat-producing equipment. This may cause inaccurate temperature control.
- Make sure the device is not exposed to direct sunlight or facing a very dark corner. This may cause the automatic screen awake feature to not work properly.
- Do not place mirrors, ceramics, or other reflective objects within 1 meter at the 12 o'clock direction in front of the touchscreen. This may cause the automatic screen awake feature to not work properly.

❗ NOTE: If the thermostat doesn't automatically turn on or suddenly shuts down after turning on the power, it may be due to insufficient power supply from the indoor unit. It is recommended that you connect the R and C terminals of the thermostat with the R and C terminals of the indoor unit to obtain additional power. You can also contact professional installers for assistance. For more information, please contact your sales representative.
Turn on the power to your system by using the master switch or breaker box.
