You can set the heating times for each heating circuit in the
HK2 Time programme heating menu.
Up to three heating times can be programmed per day or
block. The control system operates according to the heating
curve and the target room temperature.
Factory setting: Mo. – Su. 0:00 – 24:00 hours
The set back times can be dispensed with, depending on
the tariff agreement with the power company or the con-
struction of the house.
Power companies offer their own discounted tariffs for heat
pumps. It can make sense on economic grounds to make
use of the more favourable off-peak power.
In low-energy houses (in Germany standard as of 1st Febru-
ary 2002, Energy Conservation Regulation), the room tem-
perature reduction can be dispensed with owing to low heat
losses.
The desired night set back temp. must be set in
