ing.
b. Make sure that at least 15" of supply wire
extends into the roof opening.
c. In a multiple zone installation, this wiring is
required in only one of the 14-1/4" x 14-1/4"
(±1/8") openings.
3. If a Remote Temperature Sensor is used, the

feature) is to be used with the control, two wires
must be routed to the roof opening of the zone to
be managed. The signal required for this function is
a normally open relay contact. When the EMS calls
for the compressor to shut off, the relay contacts
should close. Make sure at least 15" of the EMS
wires extend into the roof opening.
