54 switch-on threshold V1.0.0.0
Switch-off hysteresis for the lower control range
If the actual value falls below the setpoint minus the value set in this parameter, the burner is
switched on again.
Enter the switch-on point as the difference to the setpoint.
Switch on value = setpoint value - parameter content.
Example: The burner shall start at 110.
Setpoint value = 120, parameter value = 10, switch-on point = 120 - 10 = 110.
If the burner should switch on again above the setpoint, negative values can also be
entered. Thereby corresponds -1 = 65535 and -999 = 64537.
Parameter content = 65536 - difference.
Example: The burner shall start at 125.
Setpoint value = 120, parameter value = 65536 - 5 = 65531, switch-on point = 120 - (-5) =
125. Write: 0/GUI/UI

55 Switch-off threshold for the upper control range V1.0.0.0
Switch-off hysteresis of the upper control range in °C or bar (x.xx)
Input of the upper control range. If the actual value exceeds the setpoint by this value, the
burner runs at base fire.
The value entered corresponds to the difference between the current setpoint and the upper
limit of the control range. Depending on the setting in P 61, the content is interpreted as °C
(directly without decimal point) as bar (resolution 0.1 bar - range 0.1 to 99.9 bar) or in digits. Write: 0/GUI/UI
