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

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
