5.3.1.3 Boiler
1 Current status / phase of boiler
2 Remaining duration of current phase (e.g. burning)
3 Next phase of boiler
4 Phase after next phase of boiler
5 Cause of termination of most recent heating phase, with time of occurrence
5.3.1.4 Buffer
Charging starts when the time is within an active time window and the upper buffer temperature is below the "Switch
on temperature" setting. If the lower buffer temperature rises to above the "Switch off temperature" setting, charging
stops.
If the time window expires during a charge cycle, the cycle is continued until the deactivation temperature is reached.
1 Current upper buffer temperature
(activation criterion)
2 Mode
Off
The buffer is never charged (exception: see frost protection page 36)
On
Charging is controlled as described above
Automatic
Like On with summer mode:
When all users connected to the buffer are Off or in summer mode
(in case of heating circuits), the buffer itself is switched off until heat is
required once more.
If no users are assigned, it behaves as in On mode.
3 Current lower buffer temperature
(deactivation criterion)
