Using the “Hot water temperature with reheating”
function can possibly cause higher energy costs.
Therefore, after this function has been activated
you are asked whether you are prepared to accept
the higher energy costs.
If you conrm this the “Hot water temperature
with reheating” function remains activated and you
can continue with .
Go to and select
to deactivate the “Hot water
temperature with reheating” function.
Return to the “Domestic hot water temperature + -”
menu. The screen now looks like this…
targeted temp. Target value for the hot water tem-
perature in the domestic hot water
storage tank
coverage hp Hot water temperature reached by the
heat pump for the last water heating
NOTICE
If the target temperature cannot be reached with
pure heat pump operation, the heat pump switches
off prematurely. The difference between the “cov-
erage hp” and “target temperature” is covered by
the second heat generator (e.g. electric heating ele-
ment) in the storage tank:
The control value for the water heating is always
the parameter “coverage hp”, this means that as
soon as the temperature falls below the “coverage
hp” control value by the water heating hysteresis
(default 2 K), water heating starts again. If the last
reached “coverage hp” value can be reached, the
heat pump tries to approach the target value again,
in 0.5K steps. If this is not possible, the heat pump
switches off and the second heat generator heats
the water until the target value is reached.
Select menu eld „targeted temp.“ and set required
temperature…
NOTICE
In conjunction with domestic hot water tanks rec-
ommended by the manufacturer, your heat pump
can generate domestic hot water temperatures
which are around 7 K lower than the maximum
ow temperature of your heat pump.
