Here you set the start and stop temperature of the hot
water for the different comfort options in menu 2.2 as
well as the stop temperature for periodic increase in
menu 2.9.1.
If several compressors are available set the difference
between engagement disengagement of them during
hot water charging and fixed condensing.
For a higher charge output click the high output selec-
tion.
With "high power" activated, the hot water is charged
with greater power than standard mode and therefore
has a faster recharging time.

can be set for each system. Climate systems 2 - 8 can-
not be set to a higher max supply temperature than cli-
mate system 1.
Caution
