3. Anti-frozen Switch: This option allows you to turn frost protection on / off.
4. Anti-frozen Temperature: Adjust the frost protection trigger temperature.
5. Floor temperature limit: If you choose both sensors, floor temp limit must be set to protect floor.
6. Temperature Tolerance: The value is 1°C. The thermostat will start to heat when the actual temperature is 1°C
lower than set temperature and stop heating when the actual temperature is 1°C higher than set temperature.
7. °F / °C: °C and °F can be selected.
8. Sensor selection:
Floor sensor: Floor sensor must be used when the thermostat is used with electric underfloor heating or is
not installed in the same room as the heated floor.
Room sensor: Heating controlled with the air sensor only.
Both sensors: Controlling roomtemperaturewith floor temperature limitation as perfloor temperature limit above.
9. Schedule: Select a weekly timer schedule. There are two options:
7: each day from Mon to Sun can be set individually.
