1192 Set flow temperature limits, heating/cooling circuit 1
1192.0 Min. flow temperature, heating, heating/cooling circuit 1
Set flow temperature limit for heating mode via heat-
ing/cooling circuit 1
The set flow temperature for heating mode results from
the following:
■
Weather-compensated heating mode: In line with the
set heating curve and the set room temperature
■
Room temperature-dependent heating mode (room
temperature sensor required): From the differential
between the set and the actual room temperature
If the calculation results in a lower set flow temperature
than the value set here, the set flow temperature will
be limited to this value.
This value cannot be set higher than max. value in
parameter 1192.1.
