Part 2: Overview of display values and settings
34
DYN DOWNWARD (dynamic heat generator
deactivation [K])
Small value = fast deactivation
Large value = slow deactivation
E
Values set to high can lead to overheating and
triggering the STB
Calculation: If the cumulative system deviation in Kelvin
reaches the set value A, this results in deactivation of all
heat generators.
RESET TIME (resetting time for I-Controller)
E
Control value: Changing this value can cause the
control system to overshoot. The recommended default
settings should be retained.
SEQUENCE 1)
Entry of the sequence in which the heat generators are set
into operation in sequence 1. => Selection of start no. =>
Prog. button => Entry of the HS number
SEQUENCE 2 (heat generator sequence 2)
Entry of the sequence in which the heat generators are set
into operation in sequence 2. => Selection of start no. =>
Prog. button => Entry of the heat generator number
!
With respect to two-stage heat generators, the
second stage is always switched after the first stage.
SEQ MODE (sequence change mode)
01 = Only heat generator sequence 1
02 = Only heat generator 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 heat generators with a different
nominal power: When the second HS is activated, the first
HS is put out of operation until activated again.
05 = Rotating heat generator sequence; the first HS of the
sequence is placed in last position of the current sequence
after the sequence switching time has elapsed.
06 = New heat generator 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).
BOILER SEQ
(time to sequence change)
For operation with at least 2 heat generators there is the
option to swap the HS sequence after the operating hours
specified here of the first heat generator of the active
sequence.
LOCK TIME
(delay time for next stage)
Min. delay time for switching on the next stage after a
stage has been switched on or is being switched off.
