Control types:
When using a room temperature sensor there are 3
different types of control to choose from.
SETTING CONTROL TYPE
- - - % Simple control according to outdoor conditions *
Control according to outdoor conditions with room influence *
1...99 %
100 % Control according to room temperature only
Requires the connection of an outdoor sensor

Simple control according to outdoor
conditions
The flow temperature is computed via the heating
curve according to the composite outdoor
temperature. This type of control requires proper
adjustment of the heating curve, as the control
does not take the room temperature into account
for this adjustment.
Control according to outdoor
conditions with room influence
The difference between the room temperature and
the setpoint value is measured and taken into
account for temperature control. This enables
taking into account possible heat inputs and
ensures a more accurate room temperature control.
The influence of the difference is defined as a
percentage. The better the installation in the
reference room (accurate room temperature,
correct installation location, etc.) the higher will be
the value that can be set.
Example:
Approx 60%: the reference room is appropriate
Approx 20%: the reference room is inappropriate
FUNCTION
Room influence
Information:
Activation of the function requires taking into
account the following requirements:
- A room sensor must be connected.
The "room influence" parameter must be set
-
between 1 and 99.
- The reference room (where the room sensor is
installed) must not contain adjusted thermostatic
valves. If present in the room, these valves must
be fully open.
Control according to
room temperature only
The flow temperature is adjusted according to the
room temperature setpoint, the current room
temperature and its evolution. A slight increase in
room temperature, for example, causes an
immediate drop in the flow temperature.
Information:
Activation of the function requires taking into
account the following requirements:
- A room sensor must be connected.
The "room influence" parameter must be set
-
to 100%.
The reference room (where the room sensor is
installed) must not contain adjusted thermostatic
valves. If present in the room, these valves must be
fully open.
