2.20.1
No heat generation or BMU
If the controller is used in combination with a BMU, only a certain part of the heat
source functions are active, such as: protective boiler start-up. In that case, boiler
temperature control by the burner must be fully ensured by the BMU.
If no BMU is connected, heat source functions are no longer active.
2.20.2
Multi-stage burners
Boiler temperature control
Generation of the boiler temperature setpoint is accomplished based on maximum
selection. Also refer to "generation of boiler temperature setpoint" in Index.
With multi-stage burners, the basic load is covered by cycling the first stage. For that
purpose, the boiler's switching differential can be adjusted.
The second stage is activated and deactivated via the release and reset integral, which
is used until full load is reached.
For burner control, minimum limitation of the burner running time is considered to
ensure no unnecessary cycling takes place in part load operation.
