Integral time
( I )
1 to 3600 sec
*PD control when set to 0 sec.
Set the time of integral action which
eliminates the offset occurring in
proportional control.
240
Derivative time
(D)
1 to 3600 sec
*PI control when set to 0 sec.
Set the time of derivative action
which prevents ripples by predicting
output changes and thus improves
control stability.
60
Anti-reset
windup (ARW)
1 to 100 % of heat-side
proportional band.
*"0" setting: integral action OFF
Overshooting and undershooting
are restricted by the integral effect.

Voltage/current inputs:
-10.0 to +10.0 % of span
Set control action deadband
between heat-side and cool-side
proportional bands.
