box, domestic distribution board).
■Notify your heating contractor.
If the heating system develops a fault
Danger
Fault messages indicate faults in
the heating system. If faults are not
rectified, they can have life threat-
ening consequences.
Do not acknowledge fault mes-
sages several times in quick suc-
cession. Inform your heating con-
tractor so the cause can be ana-
lysed and the fault rectified.
Installation room requirements
Danger
Sealed vents result in a lack of
combustion air. This leads to incom-
plete combustion and the formation
of life threatening carbon monoxide.
Never cover or close existing vents.
Do not make any subsequent modi-
fications to the building characteris-
tics that could affect safe operation
(e.g. cable/pipework routing, clad-
ding or partitions).
Danger
Easily flammable liquids and mate-
rials (e.g. naphtha/petrol, solvents,
cleaning agents, paints or paper)
can cause deflagration and fire.
Never store or use such materials
in the boiler room or in direct prox-
imity to the heating system.
!Please note
Incorrect ambient conditions can
lead to heating system damage and
can put safe operation at risk.
■Ensure ambient temperatures are
above 0 °C and below 35 °C.
■Prevent air contamination by halo-
genated hydrocarbons (e.g. as
contained in paints, solvents or
cleaning fluids) and excessive
dust (e.g. through grinding/polish-
ing work).
■Avoid continuously high humidity
levels (e.g. through continuous
drying of washing).
Extractors
The operation of appliances that extract
air to the outside (cooker hoods, extrac-
tors, air conditioning units, etc.) can cre-
ate negative pressure. If the boiler is
operated at the same time, this can lead
to a reverse flow of flue gas.

Danger
The simultaneous operation of the
boiler and appliances that extract
air to the outside can result in life
threatening poisoning due to a
reverse flow of flue gas.
Take suitable steps to ensure an
adequate supply of combustion air.
If necessary, contact your contrac-
tor.

Incorrect usage or operation of the appliance (e.g. the
appliance being opened by the system user) is prohibi-
ted and will result in an exclusion of liability. Incorrect
usage also occurs if the components in the heating
system are modified from their intended use (e.g. if the
flue gas and ventilation air paths are sealed).
Product information
The control unit is a boiler and heating circuit control
unit for the following operating modes:
■Weather-compensated operation
■Constant operation with time program
■Room temperature-dependent operation:
–Constant operation as option with room tempera-
ture controller
–OpenTherm controller
■Individual room control with/without modulation
Your heating contractor will configure the operating
mode during commissioning in accordance with your
heating system.
These instructions describe all 4 operating modes.
The setting options for room temperature-dependent
operation with an OpenTherm controller via the system
are limited:
OpenTherm controller operating instructions
Weather-compensated operation
In weather-compensated operation, the flow tempera-
ture level is controlled according to the outside temper-
ature. The lower the outside temperature, the higher
the flow temperature. This means that more heat is
provided for central heating on cold days than on
warmer days.
In weather-compensated operation, 1 heating circuit
without mixer and 1 heating circuit with mixer can be
operated with the control unit.
Constant operation with time program
In constant operation the heat generator provides
heating water with a constant flow temperature regard-
less of the outside temperature.
Heating times are controlled by a time program.
In constant operation, 1 heating circuit without mixer
and 1 heating circuit with mixer can be operated with
the control unit.
Room temperature-dependent operation
In room temperature-dependent operation, the central
heating is switched on or off subject to the room tem-
perature. The flow temperature remains constant.
In room temperature-dependent operation, 1 heating
circuit without mixer can be operated with the control
unit.
Constant operation as option with room tempera-
ture controller
In constant operation with room temperature controller,
the control unit measures the room temperature and
compares it with the selected required room tempera-
ture. If the temperatures are different, the room tem-
perature is controlled to the required value.
Note
The heating water temperature must be set high
enough in order to achieve the required room tempera-
ture.
Operating instructions for room temperature

Individual room control with/without modulation
In individual room control mode with/without modula-
tion, specific rooms can be heated differently. The ViC-
are climate sensors capture the room temperature and
compare it with the required room temperature that
has been set. If the temperatures are different, the
room temperature is regulated to the required value.
Once an internet connection has been successfully
established, operation is possible with the ViCare app.
