In case of, for instance, a holiday:

Heating and hot water OFF:

Press the - key of both keys until the lowest value 

has  been  reached.  Release  the  key  and  press 

the – key once again. The display is showing --. 

The program has thus disabled. The arrow to the 

left is off.

In case of work on the heating installation:

Make sure no heat request occurs: let no hot water 

tap run and set the room thermostat to low. Pull 

the plug from the wall socket. If the installation is 

being drained, you have to take into account that 

part of the heating water will remain in the boiler. 

Make sure that the remaining heating water in the 

boiler cannot freeze in case of frost.
