Reseting thermostat settings:
1. Unlock the device by long pressing the "Power" button if the device has been locked (the backlight is off, the "Key" sign is displayed at the top of the screen).
2. Simultaneously press and hold the "-" and "+" buttons until a beep sounds and then the device is turned OFF.
3. After performing the above manipulations, the device will reset and reboot.
4. After performing the above manipulations, you must turn ON the device manually (by holding the "Power" button).
5. After resetting and rebooting, the Wi-Fi connection and setup must be done again, according to the instructions.

Resetting system settings of the Tuya/SmartLife:
1. Open the desired device in the mobile application.
2. Open the device settings (on the main screen of the application, in the upper right corner there is an icon ✎
3. Select "Remove device" and "Disconnect and delete all data".
4. Follow the instructions on the screen to complete the operation successfully.

• After resetting and rebooting, the Wi-Fi connection as well as sensors and wireless modules connection must be done again, according to the instructions .
• Before setting up and reconnecting, you must delete the control device from your App or on the site.

• The maximum total current of the devices connected directly to the control module must not exceed 16 A, and the load power must not exceed 3500 W.
• If a thermostat is installed to control water heating systems, then a normally closed thermostatic head is connected to terminals 3 and 4 (load) according to the User Manual / Technical Certificate of the device.
• In case of non-standard application of the thermostat, its output relay is used as an ON/OFF control.
  Namely: when the temperature drops below the set value, the relay on the thermostat switches and generates a 220V AC voltage control signal at terminals 3 and 4. When the temperature rises above the setting, the voltage at terminals 3 and 4 disappears.
• The remote sensor of the thermostat can be installed both in the room to measure the air temperature, and directly on the return flow pipe of the heat carrier. The remote and built-in sensors can be used in parallel or separately, choosing the required one.

The cloud timer feature is the advanced mode of heating schedule. It supports notifications, notes, ability to control power, temperature, mode and more. When you use the timer, params that you set manually will be overwritten. You need stable internet connection to use cloud timer.
