When the thermostat is in the AUTO mode, it will operate according
to the times and temperatures that have been programmed. The user
can select from 6 dierent programs per day - each with a time and a
temperature.
There is no OFF 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 6am, and if P2 is set to be 10˚C at
8am, the thermostat will look for the temperature to be 21˚C between
6am and 8am.
If the user does not want the heating to switch on during a period,
set the temperature for the period to a lower temperature than the
expected ambient temperature.
Example: If the thermostat is programmed with the following time and
temperatures, at 6am the thermostat will look for 21˚C until 8am. From
8am until 5pm the thermostat will be switched o unless the room
temperature falls below 10˚C.
At 5pm the thermostat will start looking for 21˚C until 9pm.
