4. Setup and Installation
Proper installation is crucial for the thermostat's performance. It is recommended that installation be performed by a qualified electrician.
4.1 Mounting
The thermostat can be wall-mounted with screws or placed on a 503 back box stand. It is not designed for flush mounting.

4.2 Wiring
The thermostat requires a 220V AC mains power supply (AC 90-240V 50/60Hz). A live wire and a neutral wire are required to power the thermostat. This thermostat cannot replace battery-powered thermostats.
The output is a maximum of 5A. The NO and COM ports are dry contacts for boiler control.

6. Maintenance
The KETOTEK Smart Thermostat requires minimal maintenance. To ensure optimal performance and longevity:
- Regularly wipe the display and casing with a soft, dry cloth to remove dust and fingerprints.
- Do not use abrasive cleaners, solvents, or chemical sprays, as these can damage the surface and internal components.
- Ensure the thermostat's vents (if any) are not obstructed to allow for proper air circulation and accurate temperature sensing.
7. Troubleshooting
If you encounter issues with your KETOTEK Smart Thermostat, please refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Thermostat not powering on | No power supply; incorrect wiring. | Check mains power supply (AC 90-240V). Verify live and neutral wire connections are secure and correct. Consult a qualified electrician if unsure. |
| Cannot connect to Wi-Fi | Incorrect Wi-Fi password; 5GHz network used; thermostat too far from router; router issues. | Ensure correct 2.4GHz Wi-Fi network and password. Move thermostat closer to router. Restart your Wi-Fi router. |
| Boiler not responding to thermostat | Incorrect dry contact wiring; boiler not compatible with dry contact control; thermostat in wrong mode. | Verify NO and COM wiring to the boiler. Confirm your boiler supports dry contact control. Check if the thermostat is in heating mode and the set temperature is above the current room temperature. |
| Inaccurate temperature reading | Thermostat placed near heat source/draft; calibration needed. | Relocate thermostat away from direct sunlight, drafts, or heat sources. Use the temperature calibration feature in the app or thermostat settings to adjust. |
| App control not working | No internet connection; app not updated; thermostat offline. | Check your home internet connection. Ensure the Smart Life/Tuya app is updated to the latest version. Verify the thermostat is connected to Wi-Fi (Wi-Fi symbol on display). |
If problems persist, please contact KETOTEK customer support for further assistance.
