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.
