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.

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.
