Using one PID control algorithm, the
controller can handle two different
outputs, one of these performs the
Heat action, the other one the Cool
action.
It is possible to overlap the
outputs.
The dead band parameter
d.bnd
is
the zone where it is possible to
separate or overlap the Heat and
Cool actions.
The Cool action can be adjusted
using the relative cool gain
parameter
r.C.G
¢
.
To limit the Heat and Cool outputs
the parameters Control Output High
Limit
OP. H
and Cool Control
Output High Limit
0p.HC
can be
used.
When there is an overlap, the
displayed output
OU
t
shows the
sum of the Heat and Cool outputs.
