KM 15 Modulation level,
stop
and
KM 16 Modulation level,
start
a) For modulating boilers (KM 02 = 3)
Starting boilers:
Boiler 1 is started when the overall modulation level is > 0.
An additional boiler is started, subject to the boiler sequence,
if the set modulation level of the active boilers exceeds the
programmed starting level (modulation level, start) and the
blocking time has expired. In this case, the blocking time will be
invoked.
Shutting boilers down:
An additional boiler is started, subject to the boiler sequence,
if the set modulation level of the active boilers exceeds the
programmed starting level (modulation level, start) and the
blocking time has expired. If only one boiler is still in operation,
that boiler will be shut down if the actual header temperature >
set header temperature + hysteresis.
Soft start phase:
Soft start only applies to the lead boiler and not to the starting of
additional boilers. It also applies if only one boiler is connected
to the KM. Once the blocking time has expired and the overall
modulation level > 0, the parmeter value "Modulation level,
stop" will be transferred to the lead boiler within the  rst three
minutes. Soft start ends after the expiry of three minutes or
after the actual header temperature > set header temperature
+ header temperature hysteresis. The factory setting of 30%
relates to boilers with a modulation range of 30 - 100%.
