5.1.19.2 Control Range
Select parameter no. 802 and 803
Nr. FMS ETA Short Text Description Min Max Default
802 0 0 EinschPt Burner start point 999 999 1
Enter the switching point of the firing rate controller as
the difference to the set point.
[Switching point] = [setpoint] - [parameter content]
e. g. : burner should switch on at 110.
setpoint = 120, parameter content = 10,
110 = 120 - 10
If the burner shall start above the setpoint,
you may enter negative values as well.
Therefore the following values correspond:
-1 = 65535 and -999 = 94537
Parameter content = 65536 - difference
i. e.: burner shall switch on at 125.
setpoint = 120, parameter content = 65536 - 5 = 65531
switching point value= 120 - (-5) = 125
803 0 0 Regelb.O upper Control range 0 999 10
(difference to the set point) in ° C or bar (xx.x)
Enter the upper control range limit.
The entered value corresponds to the difference
between the actual set point and the upper limit of the
control range.
Depending on the content of Parameter 809, the con-
tent of this parameter is interpreted as ° C (directly with-
out decimal point) as bar (resolution 0.1 bar, i.e. range
from 0.1 to 99.9 bar) or in digit.
