NOTE
Incorrect settings in the service menus can
damage the heat pump.
MENU 5.1 - OPERATING SETTINGS
Operating settings can be made for the heat pump in
the sub menus.
MENU 5.1.1 - HOT WATER SETTINGS
The hot water settings require that hot water production
is activated in menu 5.2.4 accessories.
economy
Setting range start temp. economy: 5 – 55 °C
Factory setting start temp. economy: 38 °C
Setting range stop temp. economy: 5 – 60 °C
Factory setting stop temp. economy: 48 °C
normal
Setting range start temp. normal: 5 – 60 °C
Factory setting start temp. normal: 41 °C
Setting range stop temp. normal: 5 – 65 °C
Factory setting stop temp. normal: 50 °C
luxury
Setting range start temp. lux: 5 – 70 °C
Factory setting start temp. lux: 44 °C
Setting range stop temp. lux: 5 – 70 °C
Factory setting stop temp. lux: 53 °C
stop temp. per. increase
Setting range: 55 – 70 °C
Factory setting: 55 °C
charge method
Setting range: target temp, delta temp
Default value: delta temp
high power
Setting range: on/off
Factory setting: off
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.
The charge method for hot water operation is selected
here. “delta temp” is recommended for heaters with
charge coil, “target temp” for double-jacketed heaters
and heaters with hot water coil.
With “high power” activated, the hot water is charged
with greater power than standard mode and therefore
has a faster recharging time.
MENU 5.1.2 - MAX FLOW LINE
TEMPERATURE
climate system
Setting range: 20-80 °C
Default value: 60 °C
Set the maximum supply temperature for the climate
system here. If the installation has more than one cli-
mate system, individual maximum supply temperatures
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
For underfloor heating systems, max flow line
temperature should normally be set to between
35 and 45°C.
Check the max floor temperature with your
floor supplier.
MENU 5.1.3 - MAX DIFF FLOW LINE TEMP.
max diff compressor
Setting range: 1 – 25 °C
Default value: 10 °C
max diff addition
Setting range: 1 – 24 °C
Default value: 3 °C
Here you set the maximum permitted difference
between the calculated and actual supply temperature
in the event of compressor or additional heat mode re-
spectively. Max diff. additional heat can never exceed
max diff. compressor
max diff compressor
If the current supply temperature exceeds the calculated
supply by set value, the degree minute value is set to
+2. The compressor in the heat pump stops if there is
only a heating demand.
max diff addition
If “addition” is selected and activated in menu 4.2 and
the current supply temperature exceeds the calculated
temperature by the set value, the additional heat is
forced to stop.
