Wiring shown with dashed lines is to be furnished and
installed by the customer. All customer supplied wiring
must be copper only and must conform to NEC and
local electrical codes. Codes may require line of sight
between disconnect switch and unit.

C. Cooling only (or Cooling with Heat) thermostat: 4 to
7 wires depending on stages of cooling and electric
heat
C. Heat Pump thermostat: 6 to 9 wires depending on
T’stat options and stages of cooling and heating
D. Wiring between indoor and outdoor unit: 5 to 11
wires depending on unit control options*
E. Zone Sensor: 4 to 7 wires depending on zone sensor
model*
*Communication signal wires require twisted pairs.
Refer to unit schematics for identification of twisted
pairs.
NNootteess::
1. When electric heater accessory is used,
single point power entry or dual point power
entry is field optional. Single point power
entry option is through electric heater only.
2. ***Choose only one of the following;
Thermostat, Mechanical Zone Sensor,
Programmable Zone Sensor Panel or BAS
Zone Sensor.
IImmppoorrttaanntt:: For the EDC switch to be functional and
thereby facilitate reliable unit operation,
make the EDC connections from the indoor
to the outdoor control boxes.

Complete this checklist once the unit is installed to
verify that all recommended procedures have been
accomplished before the system is started. Operational
checks cannot be performed until the outdoor unit is
installed and system interconnection is complete.
☐ Verify that the unit electrical power is disconnected.
