State
On = heat generation on
Off = heat generation off
Cause
Here, the reason for the state of heat generation is
given. It should be considered that the boiler sequence
may be deactivated while the main pump is still running,
e.g. due to frost protection or overtemperature protec-
tion.
Main flow temperature
• Actual value below setpoint:
If the actual boiler temperature is lower than the set-
point for a longer period of time, additional boilers will
be released. The time of release depends especially
on the differential of these 2 values.
• Actual value above setpoint:
If the actual value remains above the setpoint for a
longer period of time, released boilers will be locked.
Return temperature
This is the temperature of the water returning to the
boiler from the consumers (heating circuit, DHW circuit).
