2426.0 Enable economy function, outside temperature, heating/cooling circuit 1
Energy saving function for the heating circuit pump of
heating/cooling circuit 1 for weather-compensated cen-
tral heating
Value Meaning
0 Energy saving function off
1 Energy saving function on:
■
If the adjusted outside temperature ex-
ceeds the set room temperature plus the
value in parameter 2426.1, the circulation
pump switches off.
■
If the adjusted outside temperature falls
below the set room temperature plus the
value in parameter 2426.1 – 1 K, the circu-
lation pump switches back on.
2426.1 Hysteresis, economy function, outside temperature, heating/cooling circuit 1
Hysteresis for energy saving function of the heating
circuit pump of heating/cooling circuit 1 for weather-
compensated central heating:
Energy saving function is active if parameter 2426.0 is
set to 1.
Conditions for starting and stopping the heating circuit
pump:
■
If the adjusted outside temperature exceeds the set
room temperature plus the value in parame-
ter 2426.1, the circulation pump switches off.
■
If the adjusted outside temperature falls below the
set room temperature plus the value in parame-
ter 2426.1 – 1 K, the circulation pump switches back
on.
2427 Energy saving function, heating/cooling circuit 2
2427.0 Enable economy function, outside temperature, heating/cooling circuit 2
Energy saving function for the heating circuit pump of
heating/cooling circuit 2 for weather-compensated cen-
tral heating
Value Meaning
0 Energy saving function off
1 Energy saving function on:
■
If the adjusted outside temperature ex-
ceeds the set room temperature plus the
value in parameter 2427.1, the circulation
pump switches off.
■
If the adjusted outside temperature falls
below the set room temperature plus the
value in parameter 2427.1 – 1 K, the circu-
lation pump switches back on.
2427.1 Hysteresis, economy function, outside temperature, heating/cooling circuit 2
Hysteresis for energy saving function of the heating
circuit pump of heating/cooling circuit 2 for weather-
compensated central heating:
Energy saving function is active if parameter 2427.0 is
set to 1.
Conditions for starting and stopping the heating circuit
pump:
■
If the adjusted outside temperature exceeds the set
room temperature plus the value in parame-
ter 2427.1, the circulation pump switches off.
■
If the adjusted outside temperature falls below the
set room temperature plus the value in parame-
ter 2427.1 – 1 K, the circulation pump switches back
on.
