Vitocal 300-G is a brine/water heat pump
with electric drive for supplying heat to
up to three heating circuits and one DHW
cylinder.
With matching accessories, the heat
pump can also be used to cool the build-
ing.
Your system is preset at the factory
The control unit is preset at the factory.
Your heating system is ready for use
after selecting a specific operating mode
(see from page 18):
■ Central heating with standard room
temperature (20 °C) all day.
■ DHW is heated all day (50 °C).
Any installed heating water buffer cyl-
inder will be heated up.
The DHW circulation pump is switched
OFF.
■Day and time (CET) were set up in the
factory.
Winter/summertime changeover
will be implemented automatically.
You may change the standard settings
preset at the factory in accordance with
personal requirements.

During any power interruption by the
power supply utility, the display shows
the text in the screenshot.
The control unit restarts in accordance
with the selected operating mode as
soon as the power supply utility restores
the power supply.
It is technically possible to provide cen-
tral heating during power interruptions
subject to the heating system being
equipped with a heating water buffer cyl-
inder. For this, consult your local heating
contractor.

Heating circuits
Your building may be heated by several
independent heating circuits (e.g. under-
floor heating circuits or radiator cir-
cuits).
■ If several heating circuits are connec-
ted, any adjustments made at operat-
ing mode selector D (see page 9)
affect all heating circuits.
If you want to make changes, contact
your local heating contractor, who can
set a fixed temperature value for indi-
vidual heating circuits.
■ If a remote control (e.g. Vitotrol 200) is
connected to a heating circuit, the
operating mode set at the remote con-
trol applies to this heating circuit.
Note
If the operating mode selector D (see
page 9) is set to
h
, this manual mode
also applies to the heating circuits with
remote control.
Control principles
■ All operating steps start from "Main
menu".
■ If the menu items listed cannot be dis-
played in their entirety, use the key
"Further menu items" to jump to fur-
ther menu items.
Call display menus and system compo-
nents by pressing the following keys:
■"Standard display" with change to
"Main menu"
■"Device settings"
■"Programming"
Subject to system version, the options
available can be found in the menu tree
(see page 13).

The commissioning and adaptation of the control unit to local conditions and the
structural characteristics of the building must be carried out by your heating contrac-
tor.
A
1. Check the system pressure at the
pressure gauge: The system pres-
sure is too low if the indicator points
to the area below 1.2 bar. In such
cases contact your local heating con-
tractor.
2. Switch ON the power supply, e.g. at
a separate MCB/fuse or a main iso-
lator.
3. Turn the ON/OFF switch A ON.
After a short while, the current oper-
ating conditions and selected set
temperatures appear on the display.
Your heat pump is now ready to oper-
ate.
Stopping the heat pump
If you do not want to use your heat pump
for a short time, e.g. during a holiday,
enable the holiday program (see
page 25) or switch the operating mode
selector to standby 9 (see page 19).
We also recommend you switch your
heat pump to standby, if it will not be
required for longer periods (several
months).
■ The frost protection of the system is
ensured in standby mode; however, at
temperatures below −20 °C, only if an
electric heater (instantaneous heating
water heater in the heating flow,
accessory) is installed.
■ The circulation pumps are briefly star-
ted every 24 hours to prevent them
from seizing up.
If you do not want to use your heat
pump, you can stop it at the ON/OFF
switch.
■ Frost protection is no longer enabled.
■ All control unit settings remain intact.
We recommend you contact your local
heating contractor before and after shut-
ting down your heat pump for longer peri-
ods.
Where necessary, your contractor can
then take certain steps, e.g. protecting
the system against frost.
Start-up/shutdown
Starting the heat pump
5592 568 GB

17
You want to heat your rooms and have DHW available, or cool your rooms at high
outside temperatures.
Note
Central heating will only take place during the heating season. The heating season
is calculated from the difference between the outside temperature and the default
room temperature. The starting limit (heating temperature differential) that relates to
the outside temperature can be set by your heating contractor.
Cooling function
"Natural Cooling" (NC)
During the summer months the temper-
ature level of the brine or water circuit
can be used to cool the building "natu-
rally".
The natural cooling (NC) function is a
method of cooling buildings that saves a
considerable amount of energy.
All that is needed is a small amount of
electricity for the circulation pumps to
access the "cooling source" in the
ground.
The capacity of the natural cooling func-
tion cannot generally be compared with
that of air-conditioning systems. Natural
cooling provides no dehumidification.
The refrigerating capacity depends on
the temperature, which is subject to sea-
sonal fluctuations. Experience has
shown that the cooling capacity is higher
at the beginning of summer than at the
end.
Underfloor heating systems and con-
crete core tempering are available for
cooling the building; radiator heating
systems are unsuitable for this pur-
pose.
"Active Cooling" (AC)
Together with the heat pump, the AC-
Box (accessory) enables active cooling
(AC mode) and natural cooling (NC
mode). The AC-Box is linked directly to
the heat pump and enables an external
circulation reversal to actively cool living
areas in summer. The following can, for
example, be connected to the AC-Box:
Fan convectors, cooling ceilings/sails
and underfloor cooling. The active cool-
ing function has a greater capacity than
natural cooling.
■ If the cooling function is integrated into
a heating circuit, it is only activated
when outside temperatures are high.
■ The starting limit (cooling temperature
differential) that relates to the outside
temperature can be set by your heat-
ing contractor.
■ The cooling function will be enabled
via the room temperature if the natural
cooling function is designed as a sep-
arate cooling circuit.
