1398.1 Summer saving temperature threshold, heating/cooling circuit 4
Heating limit for economy function, outside tempera-
ture, heating/cooling circuit 4:
The economy function can be activated so that the
rooms are not heated unnecessarily when outside tem-
peratures are mild (parameter 1398.0). The required
limit temperature (heating limit) is set for heating/cool-
ing circuit 1 in this parameter.
■
If the adjusted outside temperature (parame-
ter 919.0) exceeds the limit temperature by 2 K,
room heating is switched off. The heating circuit
pump is off.
■
If the adjusted outside temperature falls 2 K below
the limit temperature, room heating is switched on.
The heating circuit pump is running.
1627 External set temperature for heating/cooling circuit 1
1627.0 External circuit fixed target temperature, heating/cooling circuit 1
Set flow temperature, external demand, heating/cool-
ing circuit 1:
Set flow temperature for heating/cooling circuit 1 in the
case of external demand to the heat pump, irrespec-
tive of the room temperature or actual outside temper-
ature
1628 External set temperature for heating/cooling circuit 2
1628.0 External circuit fixed target temperature, heating/cooling circuit 2
Set flow temperature, external demand, heating/cool-
ing circuit 2:
Set flow temperature for heating/cooling circuit 2 in the
case of external demand to the heat pump, irrespec-
tive of the room temperature or actual outside temper-
ature
1629 External set temperature for heating/cooling circuit 3
1629.0 External circuit fixed target temperature, heating/cooling circuit 3
Set flow temperature, external demand, heating/cool-
ing circuit 3:
Set flow temperature for heating/cooling circuit 3 in the
case of external demand to the heat pump, irrespec-
tive of the room temperature or actual outside temper-
ature
