4.4.2 Economising by using the control system cor-
rectly
Further economies can be made by the correct use of
the control system on your heat pump.
A number of tips on how to make save energy by adjust-
ing your heat pump's control system are provided
below:
— Set the correct heating flow temperature:
Your heat pump not only controls the heating flow
temperature with reference to the outside tempera-
ture, it also controls the heating flow temperature
with reference to the room temperature you have set.
Therefore select a room temperature that is just suffi-
cient for your comfort, for example 20 °C. Every de-
gree over and above that means an increase in energy
consumption of around 6 % per annum.
— Select the appropriate heating curve:
If your heat pump is used to operate underfloor heat-
ing, you should specify a heating curve that is less
than 0.4. We recommend that radiator heating sys-
tems are configured in such a way that they can still
function effectively at extremely low outside tempera-
tures with a maximum flow temperature of 50 °C; this
corresponds to heating curves of less than 0.7.
— Choose an appropriate hot water temperature set-
ting:
The hot water set target temperature you specify
should be just enough to satisfy your consumption
requirements and no higher. Any further heating
results in unnecessary power consumption, and hot
water temperatures of more than 60 °C also lead to
increased lime scale production. We recommend that
hot water generation be achieved without the electric
auxiliary heating; by this method, the maximum hot
water temperature is determined by the high pressure
cut-out in the heat pump cooling circuit. This cut-out
corresponds to a maximum hot water temperature of
approx. 58 °C.
— Setting of heating times that take individual re-
quirements into account:
Use the timer programs for heating and hot water. Set
the times on the basis of your typical daily routine and
corresponding heat demand.
— Select the correct operating mode:
For the times that you are asleep or away, we recom-
mend that you switch the heating to set-back mode.
—Heat uniformly:
Through appropriate structuring of a heating pro-
gramme, you can arrange for all the rooms in your
house to be uniformly heated in accordance with your
pattern of use.

—Use thermostatic radiator valves:
— Optimise use of the circulation pump:
— Consult your expert technician:
You will find these and other energy saving tips in
Chap. 5.5. The controller settings that can potentially
save energy are described there.
You can adjust the room temperature to suit your in-
dividual requirements and ensure effective operation
of your heating installation using the thermostatic
valves in combination with a room temperature regu-
lator (weather compensator).
Adapt the operating times of the circulation pump to
actual requirements.
He can adjust your heat pump installation to suit your
personal requirements.
