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.

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.
