The Vitocal 200-G is a brine/water heat pump with an electric drive.
&Up to two heating circuits (one with mixer) can be heated.
&Any peak demand can be covered by an integral electric heater (mono-mode
operation), which is available as an accessory.
&The control side of this equipment is prepared for DHW heating using an
external DHW cylinder and for the control of a DHW circulation pump.
&The control of the components required for the natural cooling function is pre-
pared.
Your system is preset at the factory
The control unit is preset at the fac-
tory.
Your heating system is ready for use
after selecting a specific operating
mode (see from page 12):
&Central heating with standard room
temperature (20 °C) all day.
&Subject to a DHW cylinder being
installed, the DHW will be heated all
day.
Any installed heating water buffer
cylinder will be heated up.
The DHW circulation pump is
switched OFF.
&Day and time (CET) were set up in
the factory.
Winter/summer time changeover
will be implemented automatically.
You may change the standard settings
preset at the factory in accordance
with personal requirements.
Note
All data is saved in case of power fail-
ure.

During any power interruption by the
power supply utility, the display shows
the text in the screenshot.
The control unit restarts in accor-
dance with the selected operating
mode as soon as the utility restores
the power supply.
Subject to the type of power supply,
the interruption may affect either the
heat pump or only the instantaneous
heating water heater (accessories) or
both.
It is technically possible to provide
central heating during power interrup-
tions subject to the heating system
being equipped with a heating water
buffer cylinder. For this, consult your
local heating contractor.

a remote control unit is connected (see page 00).
Otherwise the fault indicator will illuminate at the remote control.

The commissioning and matching of the control unit to local conditions and the
structural characteristics of the building must be carried out by your heating
contractor.
1. Check the system pressure at the
pressure gauge: The system pres-
sure is too low if the indicator points
totheareabelow1.2bar.Insuch
cases contact your local heating
contractor.
2. Switch ON the power supply, e.g. at
a separate fuse or a main isolator.
3. Switch the system ON/OFF
switch AON;
after a short while, the selected set
temperatures and the current oper-
ating conditions are shown on the
display.
Your system is now ready for use.
Shutting down the heating system
If you do not want to use your heat
pump (for example during a summer
holiday), select the holiday program
(see page 19) or switch the operating
mode selector to "Standby" (see
page 14).
The system is protected against frost
in standby mode.
Frost protection is disabled and
pumps may seize up, if the equipment
is shut down at the system ON/OFF
switch.
However, in standby mode, all con-
nected pumps, for which this is
required, will be started daily for 10
seconds. This prevents the pumps
seizing up.

Start-up/shutdown
5592 534 GB

Subject to two heating circuits being connected, all settings made at the operat-
ing mode selector affect both heating circuits.
Central heating
Central heating will only take place during the heating season. The heating sea-
son will be determined subject to the outside temperature. The start up limit
(heating limit temperature) that relates to the outside temperature, can be
selected by your heating contractor.
Natural cooling function
The natural cooling function will only be applied when outside temperatures are
high. The start up limit (cooling limit temperature) that relates to the outside tem-
perature, can be selected by your heating contractor.
Scope
The operating modes described in the
following relate to a fully equipped
heat pump system.
Where individual components are not
installed (e.g. DHW cylinder, heating
water buffer cylinder and the natural
cooling function), then the corre-
sponding functions will also not be
available.

operating mode selector.
2. At what time central heating takes
place in programmed mode (u)
with either standard or reduced
room temperature is subject to the
selected switching times (see
page 18).
Setting a standard room temperature
In the delivered condition, the standard room temperature is set to 20 °C with
the rotary selector sset to its centre position. You can adjust this temperature
by ±5 °C at the rotary selector s, without altering the programmed values (see
page 17).
Select the required temperature at the
rotary selector s.
Note
If two heating circuits are installed,
this change will affect both heating
circuits.
After a short delay, the new set tem-
perature will be shown in area Gof
the display (see page 7).
Setting a reduced room temperature
In the delivered condition, the reduced room temperature is set to 14 °C with the
rotary selector mset to its centre position. You can adjust this temperature by
±5 °C at the rotary selector m, without altering the programmed values (see
page 17).

Setting switching times (time program u)
For central heating, setting the switching times can affect a changeover
between the operating modes "Standby", "Reduced", "Standard", and "Fixed
value".
You can select identical time programs for every day or individual programs
for each day separately.
When setting the switching times, take the response time of your heating sys-
tem into consideration. Select start and stop times correspondingly earlier or
utilise the "Heating circuit start optimisation" function (see page 32).
Note
From an energy point of view, continuous heating to the standard room tempera-
ture is advantageous for heat pumps. For that reason it is the factory default set-
ting.
Consult your local heating contractor before making any modifications.
The height of the bar and the abbreviation indicate the respective operating
mode associated with the displayed time (l.h. top of the display).
Note
With the "Fixed value" operating mode, the system heats to the maximum flow
temperature. This value can be set up by your local heating contractor.
For setting the standard and reduced room temperature for the "Standard"and
"Reduced" operating modes, see from page 16.

options:
&You can switch OFF central heating completely by setting the operating
mode selector to standby mode 9.
or
&You can set the central heating to minimum energy consumption (e.g. to
prevent houseplants from suffering through cold) by selecting the holiday
program.
