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 to
the 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 ON -
OFF. It sets the main output Delay time where O/P once turned OFF will
turn ON only after Delay time, regardless difference between PV & SP.
Also, Delay will be considered at every power ON.
This parameter will be prompted only if Control Logic for Output1 is
configured for Heat-Cool.
SP (set point) will be consider as (SP-Gap1) for heating.
This parameter will be prompted only if selected control mode for
output2 is Auxiliary control or an Alarm. The value of this parameter sets
the dead band between ON & OFF switching of output load.
This parameter will be prompted only if Control Logic for Output1 is
configured for Heat-Cool.
SP (set point) will be consider as (SP+Gap2) for cooling.
This parameter will be prompted only if Output2 is configured as an
Auxiliary control output OR Control Logic is configured for Heat-Cool. In
this mode, it sets the output Delay time where O/P once turned OFF will
turn ON only after Delay time, regardless difference between PV &
SP2. Also, Delay will be considered at every power ON.
This parameter will be prompted only if selected control mode for
Output2 is Soak timer. Depending on end of soak strategy, the value of
this parameter sets the activation time for OP2 when Soak timer is over.
Setting this parameter to ‘0’ will make OP2 continuously ON at the end
of Soak time till User starts the next cycle.
This parameter defines the permissible deviation of PV from SP during
soak time cycle. If PV falls outside the Soak band during soak cycle,
Timer halts. Timer will start only when PV falls within the soak band.
This parameter is ignored if set to ‘0’.
This parameter will be prompted 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.)
