81
1630.0 External circuit fixed target temperature, heating/cooling circuit 4
Set flow temperature, external demand, heating/cool-
ing circuit 4:
Set flow temperature for heating/cooling circuit 4 in the
case of external demand to the heat pump, irrespec-
tive of the room temperature or actual outside temper-
ature
2330 Function of digital input 2
2330.0 Function of digital input 2
For the potential-free contact connected to digital
input 2 (connection 143.3), the following functions can
be specified:
Value Meaning
1 No function
2 Fault message input
External appliance fault message, e.g. exter-
nal heat generator
3 Blocking heating/cooling circuit 2.
If the temperature limiter for restricting the
maximum temperature for underfloor heating
circuit 2 responds, the room heating for this
heating/cooling circuit is switched off.
2405 Constant set flow temperature, heating/cooling circuit 1
2405.0 Set flow temperature for cooling, heating/cooling circuit 1
Effective set flow temperature for cooling mode via
heating/cooling circuit 1
■
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 2409.0 or higher than the value in param-
eter 2409.1.
