Related Parameters
Proportional band (adjustment level): Page 113
This parameter sets the output dead band width for heating/cooling control. A
negative setting sets an overlapping band.
• This parameter sets an area in which the control output is 0 centering
around the set point for a heating/cooling control.
• During temperature input, the decimal point position depends on the cur-
rently selected sensor, and during analog input it depends on the “deci-
mal point” parameter setting.
Note
Set “none” as the unit for Controllers with Analog Inputs.
• This parameter sets the required manipulated variable to remove offset
during stabilization of P or PD control.
Related Parameters
Integral time (adjustment level): Page 113
PID ON/OFF (initial setting level): Page 122
This parameter sets the hysteresis for ensuring stable operation at the ON/
OFF switching point.
• For standard control, use the “hysteresis (heating)” parameter. The “hys-
teresis (cooling)” parameter cannot be used.
