Energy saving functions (setting only via software tool)

2426.1 Weather-compensated heating circuit pump logic function (only for weather-compensated control
units).
Setting
2426.2 Room temperature-dependent heating circuit pump logic (only for weather-compensated control
units with room temperature hook-up).
Setting
Only activate this function for the heating
circuit with mixer or if there is only one di-
rect heating circuit in the system.

Subscriber numbers of connected extensions

All extensions connected to the heat generator (except
the SDIO/SM1A electronics module) must have a sub-
scriber number. The subscriber number is set on rotary
switch S1 at each extension.
Observe maximum number of PlusBus subscribers,
see note in chapter "Connection".
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"

0 to 64 Setting range
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.
Explanations
If the actual room temperature is above the threshold
value (selected set room temperature plus hysteresis
in K), the heating circuit pump is switched off.
If the actual room temperature is below the threshold
value (selected set room temperature plus hysteresis
in K), the heating circuit pump is switched on.
