  Set-back mode and  System OFF

Hot water production and circulation are off. The frost 
protection function is activated.

With two independent heating circuits:

If the heating system has two independent heating cir-
cuits, the controller always assigns the mode with the 
greater heat requirement to hot water production and 
circulation. To find out which mode this is, see the table  
(

¬

 Tab. 5.1

).

Example:

If you operate Circuit 1 in "Auto" mode and Circuit 2 in 
"Comfort" mode, the controller assigns "Comfort" mode 
to hot water production and circulation.
