By a sole PID control algorithm, the
controller handles two different out-
puts, one of these performs the
Heat action, the other one the Cool
action.
It is possible to overlap the out-
puts.
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 para-
meter #r.C.Ga.
To limit the Heat and Cool outputs
the parameters
#0p. H and #0p.HC
can be used.
When there is an overlap, the dis-
played output
# OUt shows the
algebric sum of the Heat and Cool
outputs.
