13 "Room influence factor, heating circuit 2"
Setting
8

Additional settings can be made only via software tool

1667.0 Pump control, heating circuit pump 1 in standby mode
Setting
1668.0 Pump control, heating circuit pump 2 in standby mode
Setting
2426.1 Weather-compensated heating circuit pump logic function (only for weather-compensated control
units).
Setting
60
Explanations
The higher the value, the greater the influence of the
room temperature on the set flow temperature of the
heating circuit (heating curve). Operation with room
temperature hook-up must be set for the heating cir-
cuit. Change value for heating circuit with mixer only.
For a sample calculation, see chapter "Heating curve"
under "Function description"
8 Maximum limit in the delivered condition
0 to 64 Setting range
Explanations
Operating mode, heating circuit pump 1 (only when in
constant operation)
0 In "standby mode" = permanently switched off
1-24 In "standby mode", = started 1 to 24 times per day for
10 min each time
Explanations
Operating mode, heating circuit pump 2 (only when in
constant operation)
0 In "standby mode" = permanently switched off
1-24 In "standby mode", = started 1 to 24 times per day for
10 min each time
Explanations
If the outside temperature is above the threshold val-
ue (selected set room temperature plus hysteresis in
K), the heating circuit pump is switched off.
If the outside temperature is below the threshold value
(selected set room temperature plus hysteresis in K),
the heating circuit pump is switched on.
