Value Meaning
1 External demand, DHW circulation pump
If the connected button is pressed, the DHW
circulation pump runs for the duration set in
parameter 497.4.
2 External blocking
Refrigerant circuit, instantaneous heating wa-
ter heater and external heat generator (if in-
stalled) are blocked.
3 Blocking heating/cooling circuit 1.
If the temperature limiter for restricting the
maximum temperature for underfloor heating
circuit 1 responds, the room heating for this
heating/cooling circuit is switched off.
1395 Heating limit: Economy function, outside temperature, heating/cooling circuit 1
1395.0 Enable summer economy control, heating/cooling circuit 1
Heating limit, heating/cooling circuit 1:
The economy function can be activated so that the
rooms are not heated unnecessarily when outside tem-
peratures are mild. The required limit temperature
(heating limit) for the economy function is set for heat-
ing/cooling circuit 1 with parameter 1395.1.
■
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.
Value Meaning
0 Economy function inactive
1 Economy function active
1395.1 Summer saving temperature threshold, heating/cooling circuit 1
Heating limit for economy function, outside tempera-
ture, heating/cooling circuit 1:
The economy function can be activated so that the
rooms are not heated unnecessarily when outside tem-
peratures are mild (parameter 1395.0). 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.
1396 Heating limit: Economy function, outside temperature, heating/cooling circuit 2
1396.0 Enable summer economy control, heating/cooling circuit 2
Heating limit, heating/cooling circuit 2:
The economy function can be activated so that the
rooms are not heated unnecessarily when outside tem-
peratures are mild. The required limit temperature
(heating limit) is set for heating/cooling circuit 1 with
parameter 1396.1.
■
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.
