Lead strategy (3510)
The heat sources are switched on and off according to the selected
lead strategy while giving consideration to the preset output band.
In the strategy “Early on, late off”, additional boilers are switched on as
early as possible (output band min) and switched off again as late as
possible (output band min). This means that the largest possible number
of boilers are in operation, or additional boilers operate with the longest
possible on times.
Release integral source sequence (3530)
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.
Reset integral source sequence (3531)
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.
Restart lock (3532)
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.
