MODULAT DHW (only for HW-boiler)
Entry of the set modulation degree for the heat generators
in hot water operation (see HW-boiler).
SEQUENCE 1 (boiler sequence 1)
Entry of the sequence in which the boilers are set into
operation in sequence 1. => Selection of start no. => Prog.
button => Entry of the boiler number
SEQUENCE 2 (boiler sequence 2)
Entry of the sequence in which the boilers are set into
operation in sequence 2. => Selection of start no. => Prog.
button => Entry of the boiler number
!
With respect to two-stage heat generators, the
second stage is always switched after the first stage.
SEQU CHANGE (sequence change mode)
01 = Only boiler sequence 1
02 = Only boiler sequence 2
03 = Change between sequence 1 and 2 according to
operating hours of the first heat generator of the active
sequence
04 = 1/3 <-> 2/3 Switching for boilers with a different
nominal power: When the second boiler is activated, the
first is put out of operation until activated again.
05 = Rotating boiler sequence; the first boiler of the
sequence is placed in last position of the current sequence
after the sequence switching time has elapsed.
06 = New boiler sequence by means of automatic sorting
according to operating hours in the event of sequence
change (sequence change according to operating hours of
the first heat generator of the active sequence).
