ELECTRICAL WIRING
Thermostat Location
Mount the thermostat approximately five feet above the floor,
in an area that has an inside, vibration-free wall and has good
air circulation.
Movement of air must not be obstructed by furniture, door,
draperies, etc. The thermostat must not be mounted where it
will be affected by drafts, hot or cold water pipes or air ducts
in walls, radiant heat from fireplace, lamps, the sun, television,
etc. Consult the Instruction Sheet packaged with thermostat
for mounting instructions.
Five ton models have two stages of heating and two stages of
mechanical cooling. Units which have economizers may use
thermostats with two or three stages of cooling.
All other units have one stage of heating and one stage of
mechanical cooling. Units which have economizers may use
thermostats with one or two stages of cooling.
The units are designed for operation on 60 hertz current and at
voltages as shown on the rating plate. All internal wiring in the
unit is complete. It is necessary to bring in the power supply
to the contactor as shown on the unit wiring diagram which
is supplied with each unit. 24 volt wiring must be connected
between the unit control panel and the room thermostat.

Single Stage Thermostat - Two-Stage Models
To use a single stage thermostat, move jumper located to the
left of the terminal strip labeled "Stage Delay" from NONE to
"5" or "10" minutes. This selection will cause the control to run
on low stage for the selected time (5 or 10 minutes) then shift
to HIGH STAGE. This option controls both cooling and heating
modes. If the jumper is not moved, only low-stage cool and
low-stage heat will operate.
Two-Stage Heating (timed) and Two-Stage Cooling (timed)
with Single Stage Thermostat Diagram
Refer to the unit wiring diagram for electrical connections. When
installed, the unit must be electrically grounded in accordance
with local codes or in the absence of local codes, with the
National Electrical Code, ANSI/NFPA No. 70, and/or the CSA
C22.1 Electrical Code. Ensure low voltage connections are
waterproof.
