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.
set point = 120, parameter content = 65536 - 5 = 65531
switching point value= 120 - (-5) = 125

(difference to the set point 1/2) in ° C or bar (xx.x)
Enter the upper control range limit.
The entered value corresponds to the difference
between the actual setpoint 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.

Burner switch OFF point (difference to the set point)
in ° C or bar (xx.x)
Enter the firing-rate controller switch off point. The
entered value corresponds to the difference between
the current set point and the value, which shuts down
the burner. The value has to be greater than the
adjusted upper control range.(P 803)
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
