The Vitocal 300-G is a brine/water heat
pump with electric drive. It can be oper-
ated in single stage (type BW/WW) or
two-stage (type BW/WW + type BWS//
WWS) mode.
■ Heating circuits:
Up to 3 heating circuits (2 with mixers)
can be heated.
■ Dual-mode:
The heat pump supports dual mode
operation with an additional external
heat source, e.g. oil condensing boiler.
■ 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:
The control side of this equipment is
prepared for DHW heating using an
external DHW cylinder, and the control
of a DHW circulation pump.
■ Heat pump control unit:
All connected components are oper-
ated and controlled via the integral
heat pump control unit Vitotronic 200,
type WO1A with plain text menus.
Note
These operating instructions also
describe functions that are only available
with accessories. These functions are
not universally identified 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.
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.

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.
Terminology
To provide you with a better understand-
ing of the functions of your heat pump
control unit, the appendix contains the
chapter "Terminology" (see page 53).

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 20).
■ Heat your rooms with 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 needs,
e.g. differently at the weekend to the
weekdays (not for underfloor heating
systems, see page 9).
■ For room heating or room cooling,
select the heating program that meets
your current requirements:
– For short absences (a couple of
hours, e.g. shopping trips), select
"Economy mode" (not for under-
floor heating systems, see
page 9).
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 27).
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 30).
– 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 16).
■ Do not set the DHW cylinder temper-
ature B too high (see page 29).
■ Only activate the DHW circulation
pump for when DHW is drawn off reg-
ularly. Set the time program for this
(see page 34).

Information regarding heating sys-
tems with underfloor heating
Underfloor heating systems are slow,
low temperature heating systems and
only respond very slowly to short-term
temperature changes.
■ Therefore, heating with the reduced
room temperature at night and ena-
bling of "Economy mode" during
short absences do not result in signif-
icant energy savings.
■ As heat pumps are largely operated in
conjunction with underfloor heating
systems, no reduction of the room
temperature is preset at the factory.
For additional energy saving functions of
the heat pump control unit, please con-
tact your heating contractor.
Further recommendations:
■ Correct ventilation.
Briefly open windows C fully and at
the same time close thermostatic radi-
ator valves D (if no domestic ventila-
tion system is installed).
■ Close roller shutters (if installed) at
dusk.
■Set thermostatic valves D correctly.
■Never cover radiators E or thermo-
static valves D.
■ Controlled DHW consumption: A
shower generally uses less energy
than a bath.

You can change any settings on your
heat pump centrally at the programming
unit of the heat pump control unit.
If remote control units are installed in
your rooms, you can also adjust the set-
tings at the remote control units.
