(Automatically disabled when the
adaptive tuning is running).
This parameter specifies the span
of action of the overshoot control.
The lower the O.C. value is, the
smaller the overshoot will be during
a set point change.The overshoot
control doesn’t affect the PID
algorithm. If set to 1, the overshoot
control is disabled.
For each alarm it is possible to
select the following functions
non
£
none
Ltch
latching
bloc
blocking
Lt.bL
both latching and blocking
This parameter specifies the
maximum rate of change of
the Setpoint in digit / min.
When the parameter is Off,
this function is disabled.
Overshoot control
Heat / Cool
dead band
This parameter specifies the
maximum value the control output
can be set
Valve travel time
This parameter specifies the width
of the deadband between the Cool
and the Heat channel.

Hysteresis of the threshold of both
the alarms, that activate OP1 and
OP2 control output. It is specified as
a % of the full scale.
