7 Boiler controller / load controller
7.1 General
The boiler controller integrated in the LMV5 is a digital PID boiler temperature controller
/ a boiler pressure controller, which depends on the connected boiler sensor.
The controller can be operated using self-setting = adaption or by manually setting the
controller parameters (P, I, and D parts).
On fuel changeover, the control characteristics for modulating or multistage burners are
automatically adapted if required.
The internal controller is available as an option for use with the LMV51:
∂ LMV51.0 = with no load controller
∂ LMV51.1 = with load controller
For LMV50, LMV51.3, and LMV52, the load controller is integrated as standard.
