CAP/MODULE (boiler output for each stage)
Display of the HG number and the stage => Selection with
Prog button => Input/Adjustment of HG output
- - - - = Stage/ HS not available or not active
In the case of heat generators of equal capacity, release of
a HS is sufficient; e.g.:
or (2-stage)
WE 1 01 => 01
WE 1 01 => 01
WE 2 01 => 01
WE 1 02 => 01
WE 3 01 => 01
WE 2 01 => 01
WE 4 01 => 01
WE 2 02 => 01
(depending on the number of HS)
The first four released stages (power input) are switched to
the burner relays of the controller.
MIN MOD CASC (min. modulation cascade)
Every time the cascade controller calculates a total degree
of modulation greater than null and less than MIN MOD
CASC, the total degree of modulation is set to the value
MIN MOD CASC. Simultaneously, the clock inhibition is set
to 10 seconds.
HW-BOILER (number of stages for HW operation)
00 = HW preparation via header
01 - 08 = Number of heat generators in the cascade which
are coupled out of the cascade hydraulically for hot water
preparation.
