Danger
If water escapes from the appliance
there is a risk of electric shock.
■Switch off the heating system at
the external isolator (e.g. fuse
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.

Terminology
To provide you with a better understanding of the func-
tions of your control unit, some terminology is
explained. This information can be found in chapter
"Terminology" in the Appendix.
Intended use
The appliance is intended solely for installation and
operation in sealed unvented heating systems that
comply with EN 12828, with due attention paid to the
associated installation, service and operating instruc-
tions. It is only designed for heating up heating water
that is of potable water quality.
Intended use presupposes that a fixed installation in
conjunction with permissible, system-specific compo-
nents has been carried out.
The appliance is intended exclusively for domestic or
semi-domestic use; even users who have not had any
instruction are able to operate the appliance safely.
Commercial or industrial usage for a purpose other
than heating the building or DHW shall be deemed
inappropriate.
Any usage beyond this must be approved by the man-
ufacturer in each individual case.

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/without time program
■Room temperature-dependent operation (constant
operation with room thermostat)
■Individual room control via ViCare components
Your heating contractor will configure the operating
mode during commissioning in accordance with your
heating system. These instructions describe all 3 oper-
ating modes.
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 up to 2 heating circuits with mixer
can be operated with the control unit.
Constant operation
In constant operation the heat generator provides
heating water with a constant flow temperature regard-
less of the outside temperature.
In constant operation, 1 heating circuit without mixer
and up to 2 heating circuits 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.
Operation
The control unit is integrated into the heat generator
and controls all functions of your system. The control
unit is operated via a 3.5 inch black/white screen.
A communication module is integrated in the control
unit. This means the system can also be operated
remotely via the internet and an app.
Some functions can be controlled via a remote control
in weather-compensated operation or via a room tem-
perature controller in room temperature-dependent
operation.
Software licences
This product contains third party software, including
open source software. You are authorised to use this
third party software subject to compliance with the rel-
evant licensing terms.
■Licences for the communication module: See
page 40.
■Licences for the programming unit: See page 40.
Commissioning
The commissioning and matching of the appliance to
local conditions and building characteristics, as well as
instructing the user in the operation of the system,
must be carried out by your contractor.
Introductory information
Intended use (cont.)

12
As the user of new combustion equipment, you may be
obliged to notify your local flue gas inspector of the
installation [check local regulations]. Your local flue gas
inspector will also inform you [where appropriate]
about work that may have to be carried out on your
combustion equipment (such as regular checks, clean-
ing).
Your system is preset
Your heating system is preset at the factory and is
therefore ready for operation following commissioning
by your contractor:
Central heating in weather-compensated operation
■Between 06:00 and 22:00, rooms are heated to
20 °C ("Standard" temperature level).
■Between 22:00 and 06:00, rooms are heated to 3 °C
("Reduced" temperature level, frost protection).
Central heating in constant operation
■Between 06:00 and 22:00, the set flow temperature
is 60 °C ("Standard" temperature level)
■Between 22:00 and 06:00 the set flow temperature
is 20 °C ("Reduced" temperature level, frost protec-
tion)
Central heating in room temperature-dependent
operation
■The rooms are heated in accordance with the set-
tings on your room temperature controller.
DHW heating
■Between 05:30 and 22:00, the DHW is heated to
50 °C ("Standard" temperature level). Any installed
DHW circulation pump is switched on.
■Between 22:00 and 05:30, the DHW cylinder is not
reheated. Any installed DHW circulation pump is
switched off.
Note
Any DHW heating started before 22:00 remains on
until the set DHW temperature has been reached.
Frost protection
■Your heat generator and DHW cylinder (if installed)
are protected against frost.
Wintertime/summertime changeover
■This changeover is automatic.
Date and time
■The date and time were set by your heating contrac-
tor.
You can change the settings at any time to suit your
individual requirements.
Power failure
All settings are retained if there is a power failure.

Saving energy when using central heating
■Do not overheat your home. Every degree of room
temperature reduction saves up to 6 % on your heat-
ing bills.
Weather-compensated operation and room tempera-
ture-dependent operation:
Do not set your standard room temperature ("Stand-
ard" temperature level) to above 20 °C: See
page 25.
■Heat your home to the reduced temperature at night
or during regular absences:
–Weather-compensated operation:
Reduced room temperature
–Constant operation and room temperature-depend-
ent operation:
Reduced flow temperature
For this, adjust the settings in the time program for
central heating ("Time programs" "Heating"): See
page 21.
In room temperature-dependent operation, time pro-
grams for central heating can only be set at the room
temperature controller.
Operating instructions for room temperature
controller
■To switch off functions that are not required (e.g.
central heating in summer), set operating program to
"OFF" for the relevant heating circuits: See
page 25.
■If you are going away, set the "Holiday" function:
See page 29.
During the period that you are away, the room tem-
perature will be reduced and DHW heating switched
off.
Note
This function is not adjustable in room temperature-
dependent operation.
Saving energy on DHW heating
■At night or during regular absences, heat the DHW to
a lower temperature. To do so, adjust the time pro-
gram for DHW heating: See page 24.
■Switch on DHW circulation only for those times in
which you regularly use hot water. For this, adjust
the time program for the DHW circulation pump: See
page 24.
For additional energy saving functions, please contact
your contractor.
Tips for greater comfort
More comfort in your home
■Set your individual preferred temperature: See
page 25.
■Adjust the time program for your heating circuits so
that your individual preferred temperature is auto-
matically reached when you are present: See
page 21.
In room temperature-dependent operation, time pro-
grams for central heating can only be set at the room
temperature controller.
■Only for weather-compensated operation:
Adjust the heating curves so that your home is
heated with your individual preferred temperature all
year round: See page 26.
■If you need a higher room temperature in the short
term, select the "Extended heating" function: See
page 26.
Example: Late in the evening, the reduced room
temperature is set by the time program. Your guests
stay longer.

Special operating programs and functions
■"Screed drying"
This function is switched on by your contractor. Your
screed is dried in line with a set time program (tem-
perature/time profile) suitable for the relevant build-
ing materials. Your settings for central heating have
no effect on the duration of screed drying (max. 32
days). The system no longer provides DHW heating.
The "Screed drying" function can be altered or
switched off by your contractor.
■"External hook-up"
The operating program set at the control unit was
changed over by an external device, e.g. an EM-EA1
extension (DIO electronics module). The operating
program cannot be changed via the control unit for
as long as the external hook-up is enabled.
