4 - Operations

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.
