- Room temperature calibration: Calibrate the temperature detected by the room sensor.
- Floor temperature calibration: Calibrate the temperature detected by the floor sensor.
- Anti-freeze function: This option is ideal for warming plants and pets with a lower temperature. displays when the thermostat is switched off.
- It can also protect the pipework from freezing when using a water heating system.
- Floor temperature limit: If both sensors are chosen, the maximum floor temperature value can be set and the system will stop heating if the floor temperature exceeds this value.
- Temperature tolerance: Default value is 1°C. The thermostat starts when the room temperature is 1°C lower than set temperature and stops when the room temperature is 1°C higher than set temperature.
- Temperature unit: °C and °F can be selected.
- Sensor selection:
- Room sensor: Run by room sensor
- Floor sensor: Run by floor sensor
