2408.0 Set flow temperature for cooling, heating/cooling circuit 4
Effective set flow temperature for cooling mode via
heating/cooling circuit 4
Upon demand via the set room temperature, cooling
is performed with the flow temperature set here.
Note
If the cooling circuit type is reset in the commission-
ing assistant, the corresponding factory-set flow tem-
perature from parameter 2405.1 or 2405.2 will be
adopted initially.
The value cannot be set lower than the value in
parameter 2412.0 or higher than the value in param-
eter 2412.1.
2408.1 Set flow temperature, cooling, underfloor heating circuit, heating/cooling circuit 4
Do not adjust!
Factory-selected set flow temperature for cooling via
heating/cooling circuit 4
Requirement: Heating/cooling circuit 4 is configured as
an underfloor heating circuit.
2408.2 Set flow temperature, cooling with fan convector, heating/cooling circuit 4
Do not adjust!
Factory-selected set flow temperature for cooling via
heating/cooling circuit 4
Requirement: Heating/cooling circuit 4 is configured as
a fan convector.
2409 Set flow temperature limits, cooling, heating/cooling circuit 1
2409.0 Min. limit of set flow temperature for cooling, heating/cooling circuit 1
Limiting of set flow temperature for cooling via heating/
cooling circuit 1
The set flow temperature for cooling mode results from
the following:
Weather-compensated cooling mode: Constant set
flow temperature, depending on the type of cooling
circuit selected during commissioning, e.g. cooling
via underfloor heating circuit, cooling via fan convec-
tor
Room temperature-dependent cooling mode: From
the differential between the set and the actual room
temperature
If the setting results in a lower set flow temperature
than the value set here, the set flow temperature will
be limited to this value.
2409.1 Max. limit of set flow temperature for cooling, heating/cooling circuit 1
Limiting of set flow temperature for cooling via heating/
cooling circuit 1
The set flow temperature for cooling mode results from
the following:
Weather-compensated cooling mode: Constant set
flow temperature, depending on the type of cooling
circuit selected during commissioning, e.g. cooling
via underfloor heating circuit, cooling via fan convec-
tor
Room temperature-dependent cooling mode: From
the differential between the set and the actual room
temperature
