c) For two-stage boilers (KM 02 = 2; KM 15 and KM 16 exert

no inuence)

With two-stage boilers, the second stage is treated as if it were

a boiler in its own right that is always started after stage 1 and is

always shut down prior to stage 1 of that boiler.

Load split for two-stage boilers:

Stage 1 = 67%

Stage 2 = 33%

Soft start phase:

"See single stage boilers"

Additional information regarding the cascade algorithm for single stage and

two-stage boilers in conjunction with conguration 12 and parameter KM 31 = 1

In this case, the following functions do not apply:

a) Shutdown condition for the boiler started last, if the

"actual header temperature > set header temperature

+ 1 K".

b) Shutdown condition of the lead boiler if the "actual

header temperature > set header temperature +

header temperature hysteresis".

c) no soft start
