Line no. Operating line
3530 Release integral source seq
When, with the heat source currently in operation, the demand for heat cannot be met –
the difference being the release integral set here – another boiler is switched on. When
the value is increased, additional heat sources are switched on at a slower rate. When
the value is decreased, additional heat sources are switched on at a faster rate.
Line no. Operating line
3531 Reset integral source seq
When, with the heat source currently in operation, the demand for heat is exceeded by
the reset integral set here, the heat source with the highest priority is shut down. When
the value is increased, heat sources operate for longer periods of time (in the case of
surplus heat). When the value is decreased, heat sources are switched off at a faster
rate.
Line no. Operating line
3532 Restart lock
The restart lock prevents a deactivated heat source from being switched on again. It is
released again only after the set time has elapsed. This prevents too frequent switching
actions of the heat sources and ensures stable plant operating states.
Line no. Operating line
3533 Switch on delay
Correct adjustment of the switch-on delay ensures that plant operating conditions will
be stable. This prevents too frequent switching actions of the boilers (cycling).
In the case of a DHW request, the delay time is fixed at 1 minute.
Line no. Operating line
3534 Forced time basic stage
When switched on, every boiler operates with its basic stage for the period of time set
here. The next stage is released only when this period of time has elapsed.
