Subject to the type of heat pump and
accessories installed, your heating sys-
tem may be equipped as follows:
■ Heating circuits:
Up to 3 heating circuits (2 with mixers)
can be heated.
■ Dual mode:
The heat pump control unit supports
dual mode operation with an additional
heat source, e.g. an oil condensing
boiler or electric instantaneous heat-
ing water heater.
■ Cooling:
The natural cooling and active cooling
functions are supported if the required
accessories are installed. Cooling is
provided via a heating circuit, e.g.
underfloor heating circuit, or via a sep-
arate cooling circuit, e.g. chilled ceiling
or fan convector.
■ DHW heating:
DHW heating using an external DHW
cylinder, and control of a DHW circu-
lation pump are possible.
■ Heat pump control unit:
All connected components are oper-
ated and controlled via the heat pump
control unit with plain text menus.
Note
These operating instructions also
describe functions that are only available
on some heat pump models or only with
accessories. These functions are not
specially identified.
For questions relating to the extent of
functions and accessories for your heat
pump and your heating system, check
with your local heating contractor.
Commissioning
The commissioning and matching up of
the heat pump control unit to local con-
ditions and to the structural characteris-
tics of the building, plus the instruction of
the user in operating the system, must
be carried out by your heating contrac-
tor.
Your system is preset at the factory
At the factory, the heat pump control unit
is set to "Heating and DHW".

Your heating system is therefore ready
for use:
Central heating/Central cooling
■ From 00:00 to 24:00 h your rooms are
heated to 20 °C "Set room temp."
(standard heating mode).
■ If a heating water buffer cylinder is
installed, it will be heated.
■ Cooling will be switched off.
■ Your heating contractor can make fur-
ther settings for you during commis-
sioning.
You can change any settings individu-
ally at any time to suit your require-
ments (see chapter "Central heating/
cooling").
DHW heating
■ Every day, DHW is heated from 00:00
to 24:00 h to 50 °C "Set DHW tem-
perature".
■ Any installed DHW circulation pump is
switched off.
■ Your heating contractor can make fur-
ther settings for you during commis-
sioning.
You can change any settings individu-
ally at any time to suit your require-
ments (see chapter "DHW heating").
Frost protection
■ Frost protection for your heat pump,
the DHW cylinder and any heating
water buffer cylinder that may be
installed is enabled.
Note
At temperatures below
−
20 °C, the
frost protection of the heat pump, the
DHW cylinder and the heating water
buffer cylinder is only ensured if an
instantaneous heating water heater is
installed on site.
Winter/summertime changeover
■ This changeover is automatic.
Time and date
■ The day and time were set by your
heating contractor during commission-
ing.
Power failure
■ All data is saved if there is a power
failure.
Terminology
The appendix contains a chapter entitled
"Terminology" to provide you with a bet-
ter understanding of the functions of your
heat pump control unit.

Utilise the setting options offered by the
heat pump control unit and the remote
control (if installed):
■ Never overheat your rooms. Every
degree by which the room temperature
is reduced saves up to 6% on heating
costs.
Never set your room temperature
higher than 20 °C (see page 25).
■ Heating system with radiators:
Heat your rooms to the standard room
temperature during the day and the
reduced temperature at night. Set the
time program for this. Select the time
phases according to your habits, e.g.
differently at the weekend to the week-
days.
■ Heating system with underfloor heat-
ing:
Underfloor heating systems are slow,
low temperature heating systems and
only respond very slowly to short term
temperature changes.
Therefore, heating to the reduced
room temperature at night and ena-
bling "Economy mode" during short
absences do not result in significant
energy savings.
■ For central heating/cooling, select the
operating program that meets your
current requirements:
– For short absences (a few hours,
e.g. shopping trips), select "Econ-
omy mode" (not for underfloor
heating systems; see explanations
above).
As long as economy mode is activa-
ted, the room temperature is
reduced.
– If you are going away, set the "Hol-
iday program" (see page 32).
As long as the holiday program is
activated, the room temperature is
reduced and DHW heating is off.
– In summer, if you do not want to heat
any rooms but do need DHW, select
the operating program "Only
DHW" (see page 34).
– If you don't want to heat the rooms
and don't require DHW for an exten-
ded period, select the operating pro-
gram "Standby mode" (see
page 22).
■ Never set the DHW cylinder tempera-
ture too high (see page 34).
■ Only activate the DHW circulation
pump for times when DHW is drawn off
regularly. Set the time program for this
(see page 38).
For additional energy saving functions of
the heat pump control unit, please con-
tact your heating contractor.

Further recommendations:
■ Correct ventilation.
Briefly open windows fully and at the
same time close thermostatic valves (if
no domestic ventilation system is
installed).
■ Close roller shutters (if installed) at
dusk.
■ Set thermostatic valves correctly.
■ Never cover radiators or thermostatic
valves.
■ Controlled DHW consumption: a
shower generally uses less energy
than a bath.
