Disconnect ALL power before servicing.
Multiple power sources may be present.
Failure to do so may cause property damage,
personal injury or death.
Thermostat
Thermostat Location
Mount the thermostat approximately 5 ft (1.5 m) 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 the thermostat for
mounting instructions.
NOTE: WGGE4524, WGGE4530, WGGE4537 and WGGE4542
units have 1 stage of mechanical cooling and 2 stages of heating.
All other units have 2 stages of heating and 2 stages of
mechanical cooling. Units which will have economizers may use
thermostats with 2 or 3 stages of cooling. All units can use
single-stage or multistage thermostats. Refer to the following
thermostat illustrations for wiring.
All units have 1 stage of heating and one stage of mechanical
cooling. Units which will have economizers may use thermostats
with 1 or 2 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. Twenty-four volt wiring must be
connected between the unit control panel and the room
thermostat.

Single-Stage Thermostat
To use a single-stage thermostat, move the jumper located to the
left of the terminal strip labeled "Stage Delay" from "NONE" to
"5 MIN" or "10 MIN." This selection will cause the control to run
on low stage for the selected time (5 or 10 minutes), and 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.

IMPORTANT:
Electrical wiring, disconnect means and over-current
protection are to be supplied by the installer. Refer to the
rating plate for the maximum over-current protection,
minimum circuit ampacity and operating voltage. See the
wiring connection diagrams in "Troubleshooting."
Install an adequate sized branch circuit disconnect,
according to the NEC, within sight of and readily accessible
to the unit.
The cable or conduit and fittings connected from the
disconnect switch to the unit wiring connections shall be
rated for outdoor use.
Check the unit rating plate to determine whether the system
is rated single phase or three phase and follow the
appropriate instructions for connecting the pigtail leads.
Plug unused side entry holes with field-supplied plugs to
keep moisture from entering the unit.
Low voltage wiring must be separated from line voltage
wiring.
