The commissioning and matching up of the heat pump
control unit to local conditions and to the structural
characteristics of the building, plus the instruction of
the user in operating the system, must be carried out
by your heating contractor.
Note
These operating instructions also describe functions
that are only available on some heat pump models or
only with accessories. These functions are not specifi-
cally identified.
For questions relating to the scope of and accessories
for your heat pump and your heating system, contact
your contractor.
Your system is preset at the factory
Your heat pump is preset at the factory and is therefore
ready for operation:
Room heating/room cooling
■
Your home will be heated to 20 °C from 06:00 to
22:00 h "Room set temperature" (standard room
temperature).
■
If a separate buffer cylinder is installed, this buffer
cylinder will be heated.
DHW heating
■
DHW is heated to "Set DHW temperature" 50 °C
every day from 05:30 to 22:00.
■
Any installed DHW circulation pump is switched off.
■
If required, the instantaneous heating water heater
built into the indoor unit can be switched to DHW
heating.
Frost protection
■
Frost protection is ensured for your heat pump, DHW
cylinder and any separate buffer cylinder that may be
installed.
Note
For outside temperatures below -20 °C and in the
case of a fault in the heat pump, only instantaneous
heating water heater built into the indoor unit is
switched on to provide frost protection for the sys-
tem.
Wintertime/summertime changeover
■
This changeover is automatic.
Date and time
■
The date and time were set by your contractor.
You can change the settings at any time to suit your
individual requirements.
Power failure
All settings are retained if there is a power failure.
Energy saving tips
Saving energy when using room heating
■
Do not overheat your home. Every degree of room
temperature reduction saves up to 6 % on your heat-
ing bills.
Do not set your standard room temperature ("Room
set temperature") to above 20 °C: See page 25.
■
Heat your home to the reduced room temperature at
night or during regular absences (not applicable to
underfloor heating). For this, adjust the settings in
the time program for room heating ("Time pro-
gram"): See page 26.
■
Adjust the heating curves so that your home is
heated with your individual preferred temperature all
year round: See page 26.
■
To switch off functions that are not required (e.g.
room heating in summer), set the operating program
to "Standby mode" for the relevant heating circuits:
See page 25.
■
If you are going away, set the "Holiday program":
See page 29.
During the period that you are away, the room tem-
perature will be reduced and DHW heating switched
off.
