Control Options on Mark IV/AC Units
Figure 12: Auxiliary Relay
Note: The auxiliary relay is designed to interface external equipment with the Mark
IV/AC board. The auxiliary relay has been provided with the components
necessary to protect from electrical damage that may occur to the Mark IV/
AC board when using standard off-the-self relays. The auxiliary relay can be
used to provide fault signals, unit operation signals, or to provide a means
for remote equipment to control the Mark IV/AC board. The orange, yellow,
and white connections are short flying leads pre-attached to the board. The
diagrams shown are some connection examples.

Operation:
In this example
the auxiliary relay contacts
can be used to indicate a
fault condition. With the
auxiliary relay connected
as shown, the normally
open contacts will close
during a fault condition.
Operation: In this example
the auxiliary relay contacts
can be used to signal
WSHP fan operation to
another device. In this
example when the
thermostat energizes the
“G” terminal the auxiliary
relay normally open
contacts will close.
