Supervisory Control Wiring

An air conditioner can be used with the supervisory contacts
on either terminals A-A or B-B. Terminals A-A can only be
used with supervisory control. Large loads can only be used
with contactor control on terminals B-B. Examples of each
system are described below.
1. The terminal strip on control module in transfer switch
has four connections for customer use. There are two
sets of "Normally Closed" contacts available. They will
be activated when generator power is required. These
can be used for supervisory control of large connected
loads on generator. Loads will be allowed to operate if
there is enough generator power available.
NOTE: There are two wireways provided to keep the
supervisory loads separated from each other.
2. Terminals "A-A" on control module are rated for
24 VAC and air conditioner contactor control. Contacts
are connected in series with the air conditioner
contactor control circuit.
