How your programmable thermostat works

When the thermostat is in AUTO mode, it will operate according to the times and temperatures that have been programmed. The user can select from 6 different programs per day – each with a time and a temperature.
There is no of time, only a higher and a lower temperature. If the user wants the thermostat to be OFF at a certain time, set the temperature for this time to be low. The thermostat will turn ON if the room temperature is lower than the setpoint for the current period. Example: If P1 is set to be 21°C at 6 am, and if P2 is set to be 10°C at 8 am, the thermostat will look for the temperature to be 21°C between 6 am and 8 am.
