The Vitocal 222-G/242-G/333-G/343-G
are brine/water heat pumps with integral
DHW cylinder. Solar collectors can be
connected to the Vitocal 242-G and 343-
G to provide DHW heating.
An instantaneous heating water heater
(accessory) can be integrated into all of
these appliances to cover peak demand
for central heating and DHW heating.
All connected components are operated
and controlled via the integral heat pump
control unit Vitotronic 200, type WO1A
with plain text menu prompts.
The individual appliances are differenti-
ated according to the following product

These operating instructions also
describe functions that are not available
with all models or only with accessories.
These functions are not universally iden-
tified in each case.
The type and extent of menu entries in
the heat pump control unit also depend
on the equipment level of your heating
system and the selected settings/adjust-
ments on the heat pump control unit.
In case of questions relating to the extent
of functions and accessories for your
heat pump and your heating system,
check with your local heating contrac-
tor.

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/cooling
■ Your rooms are heated to 20 °C "Set
room temperature" around the clock
(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
■ DHW is heated around the clock every
day. DHW is heated to 50 °C.
■ Any installed DHW circulation pump is
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.
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.

To provide you with a better understand-

control unit, the appendix contains the
chapter "Terminology" (see page 51).
Energy saving tips
B
C
D
A
Utilise the setting options offered by the
heat pump control unit A and by 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.
Set your room temperature no higher
than 20 ºC (see page 18).
■ Never set the DHW temperature too
high (see page 27).
■ Only activate the DHW circulation
pump for when DHW is drawn off reg-
ularly. Set the time program for this
(see page 31).
■ Select the program that meets your
current requirements:
– For short absences (e.g. shopping
trips), select "Economy mode"
(see page 25).
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 25).
As long as the holiday program is
activated, the room temperature is
reduced and DHW heating is OFF.
– In summer, when you don't want to
heat any rooms but do need DHW,
select the operating program "DHW
only" (see page 28).
– If you don't want to heat the rooms
and you don't require DHW for an
extended period, select the operat-
ing program "Standby mode" (see
page 15).
For additional energy saving functions of
the heat pump control unit, please con-
tact your heating contractor.

Further recommendations:
■ Correct ventilation/airing.
Briefly open windows B fully and at
the same time close thermostatic radi-
ator valves C (if no domestic ventila-
tion system is installed).
■ Close roller shutters (if installed) at
dusk.
■Set thermostatic valves C correctly.
■Never cover radiators D or thermo-
static valves C.
■ Controlled DHW consumption: A
shower generally uses less energy
than a full bath.

your rooms, you can also adjust the set-
tings at the remote control units.

Central heating
■ Central heating is only activated if the
outside temperature falls below the
heating limit. The heating limit can be
set by your local heating contractor.
Cooling via a heating/cooling circuit
■ Cooling via the heating circuit, e.g. an
underfloor heating system (see 54)
only occurs when the outside tem-
perature has exceeded the cooling
limit. The cooling limit can be set by
your local heating contractor.
Cooling via a separate cooling circuit
■ Cooling with a separate cooling circuit,
e.g. chilled ceiling or fan convector
(see page 54) occurs independent of
the outside temperature. The cooling
capacity is automatically regulated so
that the selected set room temperature
is achieved (room temperature-
dependent cooling operation, see
page 55).
This enables a separate cooling circuit
to provide cooling all year round, e.g.
for a storage room.
Note
No time program can be set for the
separate cooling circuit.
Required settings (heating/cooling)
If you want central heating or cooling,
check the following points:
■ Have you selected the heating or cool-
ing circuit?
For settings, see chapter "Selecting
the heating/cooling circuit or a sepa-
rate cooling circuit".
■ Have you set the required room tem-
perature?
For settings, see page 18.
■ Have you set the correct operating
program?
For settings, see page 19.
■ Have you set the required time pro-
gram?
For settings, see page 20.

Central heating can be split over several
heating circuits (heating circuit 1, 2 or 3).
Cooling results either through one of
these heating circuits or via a separate
cooling circuit.
For all settings relating to central heat-
ing/cooling, first select the heating/cool-
ing circuit or the separate cooling circuit
to which your changes should apply.
Example:
■"Heating circuit 1" is the heating cir-
cuit for the rooms occupied by you.
■"Heating circuit 2" is the heating cir-
cuit for the rooms of a separate apart-
ment.
■"Cooling circuit SKK" represents a
fan convector in a storage room.

Enabling electric heater for central heating
If the heat pump on its own cannot ach-
ieve the selected set room temperature,
an instantaneous heating water heater
(accessory) can be started automatically
to boost central heating.
The constant use of an instantaneous
heating water heater results in higher
power consumption, so therefore it
requires enabling.

Note
No time program can be set for any sep-

■ The time program for central heating/
cooling is made up of time phases. Set
an operating status for each time
phase ("Reduc.", "Normal", "Fixed
val.", see page 21).
At the factory, central heating is set to
operate 24/7 (one time phase from
0:00 to 24:00 h for every day of the
week with the operating status "Nor-
mal").
■ You can select up to 8 time phases.
Set the start and end points for each
time phase. Rooms are neither heated
nor cooled between these time pha-
ses; only frost protection is active.
■ You can set the time program individ-
ually.
When making adjustments, bear in
mind that your heat pump requires
some time to heat or cool the rooms to
the required temperature.
■ In the "Extended menu", you can scan
the current time program under
"Note" (page 40).
