This parameter will be prompted only if selected control action is PID. It sets
bandwidth over which the output power is adjusted depending upon the error (SV-
PV). The value of this parameter is automatically set by Auto tune function.
This parameter will be prompted only if selected control action is PID. It defines how
strongly the Controller will react to the rate of change of PV. Value of this parameter
is automatically set by Auto Tune function. If set to ‘0’, this function will be disabled.
This parameter will be prompted only if selected control action is PID. User can set
this value based on process being controlled & type of Output being selected. For
Relay O/P, cycle time should be more than 12sec & for SSR O/P, cycle time should
be less than 5 Sec.
This parameter will be prompted only if selected control action is ON-OFF. It sets the
dead band between ON & OFF switching of the Output. Larger value of hysterisis
minimize the number of ON-OFF operation of load. This increases life of actuators
like contactors but also produces large errors (between PV & SV).
This parameter will be prompted only if selected control action is PID. It sets the time
taken by PID algorithm to remove steady state error. Value of this parameter is
automatically set by Auto Tune function. If set to ‘0’, this function will be disabled.

This parameter will be prompted only if selected control action is ON-OFF. It sets the
output restart time where O/P once turned OFF will turn ON only after restart time,
regardless difference between PV & SP in Heat or Cool mode. If set to '0', O/P will be
switched without delay. Also, Delay will be applicable at every power ON.

This parameter will be promted only if selected control action is PID.This parameter
allows the user to carry out Auto Tuning function below the set point. (If tune offset is
set to 50 %, tuning will be carried out at 50 % of the set point and If set to 100 %,
tuning will be carried out at 100 % of the set point.)

This parameter will be prompted only if selected control action is PID. With this
