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.
All units have two stages of heating and two stages of mechanical
cooling. Units which will have economizers may use thermostats with
two or three stages of cooling. All units can use single stage or multi-
stage thermostats. Refer to figures later in this section for wiring.
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. The low voltage wiring must be connected between the unit
control panel and the room thermostat.
SINGLE STAGE THERMOSTAT
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.
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.
