2416.1 Stop condition, cooling, heating/cooling circuit 4
Stop condition for operation of the heating circuit pump
in heating/cooling circuit 4 for weather-compensated
room cooling:
If the adjusted outside temperature falls below the
selected set room temperature by the value set here,
the circulation pump switches off.
2421 Temperature offset, heating/cooling circuit 1
2421.0 Temperature offset, heating/cooling circuit 1
Offset at room temperature sensor for cooling, heating/
cooling circuit 1:
Requirement: ViCare climate sensor is installed in
heating/cooling circuit 1.
The correction value (offset) set here is added to the
calculated set flow temperature for heating/cooling cir-
cuit 1.
This enables the mixer to regulate more effectively and
prevents it from being permanently open.
2422 Temperature offset, heating/cooling circuit 2
2422.0 Temperature offset, heating/cooling circuit 2
Offset at room temperature sensor for cooling, heating/
cooling circuit 2:
Requirement: ViCare climate sensor is installed in
heating/cooling circuit 2.
The correction value (offset) set here is added to the
calculated set flow temperature for heating/cooling cir-
cuit 2.
This enables the mixer to regulate more effectively and
prevents it from being permanently open.
2423 Temperature offset, heating/cooling circuit 3
2423.0 Temperature offset, heating/cooling circuit 3
Offset at room temperature sensor for cooling, heating/
cooling circuit 3:
Requirement: ViCare climate sensor is installed in
heating/cooling circuit 3.
The correction value (offset) set here is added to the
calculated set flow temperature for heating/cooling cir-
cuit 3.
This enables the mixer to regulate more effectively and
prevents it from being permanently open.
2424 Temperature offset, heating/cooling circuit 4
2424.0 Temperature offset, heating/cooling circuit 4
Offset at room temperature sensor for cooling, heating/
cooling circuit 4:
Requirement: ViCare climate sensor is installed in
heating/cooling circuit 4.
The correction value (offset) set here is added to the
calculated set flow temperature for heating/cooling cir-
cuit 4.
This enables the mixer to regulate more effectively and
prevents it from being permanently open.
