Overshoot
control
(Automatically disabled when the
adaptive tuning is running).
This parameter specifies the span of
action of the overshoot control. Setting
lower values (0.99 —> 0.01) the over-
shoot generated by a Setpoint change
is reduced. The overshoot control
doesn’t affect the effectiveness of the
PID algorithm. Setting 1, the over-
shoot control is disabled.
Heat/Cool
dead band
This parameter specifies the width
of the deadband between the Cool
and the Heat channel.
Control output

Cool output
high limit
It specifies the maximum value the
control output can be set

AL2
alarm hysteresis
AL3
alarm hysteresis
Hysteresis of the threshold of both
the alarms, that activate OP1 and
OP2 control output. It is specified
as a % of the full scale.
Setpoint
low limit
Setpoint
high limit
Low / high limit of the Setpoint value.

For each alarm it is possible to
select the following functions

SECOND GROUP
Stand-by
Setpoint
Used by Timer function too.
Setpoint
ramp up
Setpoint
ramp down
This parameter specifies the max-
imum rate of change of the Setpoint
in digit/min. When the parameter is
Off
, this function is disabled.
