torque values.

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 the transfer switch control board
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.
For installer convenience, there are two wireways provided to
help keep supervisory load wires organized.
2. Terminals "A-A" on transfer switch control board
are rated for 24VAC. Connect these contacts in
series between air conditioner thermostat and air
conditioner contactor.

24 VAC
rated for 1 Amp 125 VAC. When connected with an
installer supplied contactor, it can be used to control
a large load, such as an electric hot water heater.
Contacts are connected in series with the contactor
control circuit.
