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 extent of functions and
accessories for your heat pump and your heating sys-
tem, check with your local heating contractor.
Terminology
To provide you with a better understanding of the func-
tions of your Vitotronic control unit some terminology is
explained.
The terms are marked as follows:
Further information can be found in chapter
"Terminology" in the appendix.
Your system is preset at the factory
Your heating system is preset at the factory and is
therefore ready for operation:
Central heating/Central cooling
■Your home will be heated from 00:00 to 24:00 h to
20 °C "Set room temperature" (standard room tem-
perature).
■If a heating water buffer cylinder is installed, it will be
heated.
■Any electric booster heater installed will be enabled
(see chapter "Enabling electric booster heater").
■Active cooling mode is blocked (see chapter "Ena-
bling and blocking active cooling mode").
DHW heating
■The DHW is heated every day from 00:00 to 24:00 h
to 50 °C "Set DHW temperature".
■Any installed DHW circulation pump is switched off.
■Any electric booster heater installed will be enabled
(see chapter "Enabling electric booster heater").
Frost protection
■Frost protection for your heat pump, DHW cylinder
and any heating water buffer cylinder that may be
installed is ensured.
Note
At temperatures below −15 °C, the frost protection of
the heat pump, the DHW cylinder and the heating
water buffer cylinder is only ensured if an instantane-
ous heating water heater is installed (on site).
Domestic ventilation with Vitovent 300-F
■From 00:00 to 24:00 h: Domestic ventilation in oper-
ating status "Standard".
Wintertime/summertime changeover
■This changeover is automatic.
Date and time
■The date and time were set by your heating contrac-
tor.
Your heating contractor can make further settings for
you during commissioning.
You can change the settings to suit your requirements
at any time.
Power failure
In the case of a power failure, all settings are retained.

Central heating/Central cooling
■Standard room temperature ("Set room tempera-
ture", see page 20):
Never overheat your home. Every degree of room
temperature reduction saves up to 6 % on your heat-
ing bills.
Never set your standard room temperature higher
than 20 °C.
■Time program (see page 21):
Heat your home to the standard room temperature
during the day and the reduced temperature at night
(not suitable for underfloor heating). Set the time pro-
gram for this.
■Operating program:
If you do not require central heating or cooling, select
one of the following operating programs:
–"Only DHW" (see page 26):
If you require no heating for your home in summer,
but you need hot water.
–"Standby mode" (see page 19):
If you don't need to heat your home and don't need
hot water for longer periods.
■Short absence (see page 24):
Reduce the room temperature, for example when
you go shopping (not suitable for underfloor heating
systems). For this, select "Economy mode".
■Holidays (see page 24):
If you are going away, select the "Holiday pro-
gram":
The room temperature will be reduced, and DHW
heating will be turned off. In connection with a venti-
lation unit, a lower ventilation stage will be selected.
■Ventilation/airing:
To air a room, close the thermostatic valves and
briefly open the windows fully (if no domestic ventila-
tion system has been installed).
■Roller shutters:
Close roller shutters (where installed) at dusk.
■Thermostatic valves:
Ensure that thermostatic valves are set correctly.
■Radiators:
Never place things in front of radiators or thermo-
static valves.
DHW heating
■DHW circulation pump (see page 27):
Only activate the DHW circulation pump for periods
in which DHW is regularly drawn off. Set the time
program for this.
■DHW consumption:
Consider showering instead of running a bath. A
shower generally uses less energy than a full bath.
Domestic ventilation (in conjunction with ventila-
tion units)
■Short absence (see pages 32 and 34):
Select a lower ventilation stage, for example when
going shopping. For this, select "Economy mode"
or the "Standard operation" operating program.
■Holidays (see page 35):
If you are going away, select the "Holiday pro-
gram":
A lower ventilation stage will be selected. The room
temperature will be reduced, and DHW heating will
be turned off.
Own consumption of power (in conjunction with a
photovoltaic system)
■Use the power generated by your photovoltaic sys-
tem for your heating system (see page 36).
For additional energy saving functions of the heat
pump control unit, please contact your heating contrac-
tor.
Tips for greater comfort
Central heating/Central cooling
■Standard room temperature ("Set room tempera-
ture", see page 11):
You can select your individual preferred temperature
at any time in the standard menu.
■Preferred heating circuit (see page 38):
If your heating system comprises several heating cir-
cuits, you can input the important settings for a pre-
ferred heating/cooling circuit directly in the standard
menu.
■Time program (see page 21):
Make use of the time program. In the time program,
you can set time phases with different room temper-
atures, for example different temperatures for day
and night time.
■Heating water buffer cylinder (if installed, see
page 21):
Set the time program for the heating water buffer cyl-
inder so there is always sufficient heat for your heat-
ing circuits, for example to bridge power-OFF times
imposed by your local power supply utility.
■Electric booster heater (if installed, see page 29):
Enable the electric booster heater and set up a time
program for it. The electric booster heater starts
automatically if large amounts of heat are suddenly
required.
■"Active cooling mod." (see page 30):
After enabling the active cooling mode, a high cool-
ing capacity will be available for centrally cooling
your home, when required.

■Heating curve/cooling curve (see page 22):
The heating curve enables you to individually adjust
the heating system to the actual heat demand in your
home. If set correctly, your preferred temperature will
be achieved all year round. The same applies to the
cooling curve.
■"Party mode" (see page 23):
Select "Party mode" if you want to heat your home
to a temperature that is different from that dictated by
the time program.
Example: The time program determines that in the
evening, your home is heated to a reduced room
temperature, but you have visitors staying into the
evening.
DHW heating
■Time program (see page 26 and 27):
Use the time program for DHW heating. In the time
program, you can set time phases with different
DHW temperatures, for example higher in the morn-
ings than during daytime.
Use the time program for the DHW circulation pump.
During the selected time phases, DHW will be availa-
ble at the draw-off points at the required tempera-
ture.
■"Start optimisation" (see page 27):
The start optimisation ensures that your DHW cylin-
der will be heated to the selected temperature at the
beginning of any heating phase.
■"Stop optimisation" (see page 27):
The stop optimisation ensures that your DHW cylin-
der will be heated to the selected temperature at the
end of any heating phase.
■Once-only DHW heating (see page 28):
With "1x DHW heating" the heat pump will immedi-
ately heat up the DHW cylinder, independent of any
time program.
■Electric booster heater (if installed, see page 29):
Enable the electric booster heater and set up a time
program for it. The electric booster heater starts
automatically, if the heat pump on its own cannot
heat up the DHW cylinder quickly enough, for exam-
ple during the power-OFF times enforced by the
local power supply utility.
Domestic ventilation (in conjunction with ventila-
tion units)
■"Intensive operation" (see page 34):
During "Intensive operation" you increase the air
change rate in your home, for example when cook-
ing.
Operation of air/water heat pumps
■Quieter operation (see page 31):
Select the time program for quieter operation, for
example in order to reduce the noise level of your
air/water heat pump at night.

Special operating programs E:
■"Screed drying"
This function is activated by your heating contractor.
Your screed is dried in line with a set time program
suitable for the building material (temperature:time
profile). Your settings for central heating/central cool-
ing have no effect for the duration of screed drying.
■"External hook-up"
Your heat pump control unit is regulated by a higher
ranking control unit.
■"External program"
The operating program was changed by a communi-
cations interface (e.g. Vitocom 100).
■"Holiday program"
See page 24.
Note
In the extended menu, you can call up the set operat-
ing program under "Information" (see page 40).
Time program
The following explains how to input the settings for a
time program. The special features of each individual
time program are assigned to the relevant chapters.
You can set up a time program for the following func-
tions:
■Central heating/central cooling (see page 21)
■Heating the heating water buffer cylinder (see
page 21)
■DHW heating (see page 26)
■DHW circulation pump (see page 27)
■Electric booster heater (see page 29)
■Quieter operation of air/water heat pumps (see
page 31)
■Domestic ventilation (in conjunction with a ventilation
unit, see page 33)
In the time program, divide the day into sections.
These are called time phases. It is for you to decide
what happens in these time phases. For example, they
could specify when your rooms will be heated to stand-
ard room temperature. To do this, you will need to set
an operating status.
■You can set the time program individually, to be the
same for every day of the week or different.
■You can select up to 8 time phases per day.
■For each time phase you select the start and end
points.
The selected time phase is illustrated by a white bar
on the time chart. The length of the bar reflects the
length of time.
