Cause
The user can switch the boiler off via operation.
In operating mode "Release DHW", only heat requests from DHW (digital input or via
Konnex bus) will be taken into consideration.
If "Off" is preselected, the internal frost protection function remains active. Heat re-
quests from an external consumer resulting from frost protection will also be consid-
ered.
This setting can be used to preselect a minimum request for the boiler controller, which
means that a maximum selection based on the consumers' requests will be maintained.
The boiler's state is indicated (On / Off).
It is indicated why the current state is active.
The boiler temperature setpoint will be generated based on the temperature requests
received from the consumers plus the setpoint increase.
The boiler temperature setpoint and the actual boiler temperature can be called up on
the info level.
