6.11 Boiler
6.11.1 Release threshold Outside temperature
Release of the boiler can be effected as a function of the outside temperature.
Line no. Operating line
2203 Release below outside temp
The boiler is put into operation only when the composite outside temperature lies below
this threshold. The setting range is from -50 to 50 °C. For the release, the calculation is
based on a fixed switching differential of 0.5 K.
Note!
If DHW separate circuit (5736) is activated, the boiler will still be put into operation for
DHW heating purposes even if this threshold is exceeded.
6.11.2 Full charging of buffer storage tank
Line no. Operating line
2208 Full charging buffer
Off
On
Function Full charging buffer makes it possible to switch off released heat sources only
when the buffer storage tank is fully charged, despite automatic heat generation lock.
But full charging must be demanded by the buffer storage tank.
If and when the buffer storage tank shall call for full charging can be set via Full
charging (4810).
When the function is activated, the heat source is switched off only when full charging
is ended or if, due to control of the burner, switching off must be effected.
Heat sources that are not in operation are not switched on because full charging is
required.
