2428.0 Enable economy function, outside temperature, heating/cooling circuit 3
Energy saving function for the heating circuit pump of
heating/cooling circuit 3 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 2428.1, the circulation
pump switches off.
■
If the adjusted outside temperature falls
below the set room temperature plus the
value in parameter 2428.1 – 1 K, the circu-
lation pump switches back on.
2428.1 Hysteresis, economy function, outside temperature, heating/cooling circuit 3
Hysteresis for energy saving function of the heating
circuit pump of heating/cooling circuit 3 for weather-
compensated central heating:
Energy saving function is active if parameter 2428.0 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 2428.1, the circulation pump switches off.
■
If the adjusted outside temperature falls below the
set room temperature plus the value in parame-
ter 2428.1 – 1 K, the circulation pump switches back
on.
2429 Energy saving function, heating/cooling circuit 4
2429.0 Enable economy function, outside temperature, heating/cooling circuit 4
Energy saving function for the heating circuit pump of
heating/cooling circuit 4 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 2429.1, the circulation
pump switches off.
■
If the adjusted outside temperature falls
below the set room temperature plus the
value in parameter 2429.1 – 1 K, the circu-
lation pump switches back on.
2429.1 Hysteresis, economy function, outside temperature, heating/cooling circuit 4
Hysteresis for energy saving function of the heating
circuit pump of heating/cooling circuit 4 for weather-
compensated central heating:
Energy saving function is active if parameter 2429.0 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 2429.1, the circulation pump switches off.
■
If the adjusted outside temperature falls below the
set room temperature plus the value in parame-
ter 2429.1 – 1 K, the circulation pump switches back
on.
