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.
NOTE: All units have one stage of heating and either one or
two stages of mechanical cooling. If the unit has two stages of
mechanical cooling, the thermostat must also be two stage. Refer
to figures later in this section for wiring.
TO AVOID PERSONAL INJURY, ELECTRICAL SHOCK OR DEATH,
DISCONNECT ELECTRICAL POWER BEFORE SERVICING OR
CHANGING ANY ELECTRICAL 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.

24 Volt Dehumidistat Wiring (For DP16UM* Only)
The optional usage of a dehumidistat allows the unit's circulator
blower to operate at a slightly lower speed (approximately 80%
of desired cooling speed) during a combined thermostat call for
cooling and dehumidistat call for dehumidification. This can be
done through an independent dehumidistat. This lower blower
speed enhances dehumidification of the conditioned air as it
passes through the air conditioning coil. For proper function, a
dehumidistat applied to this package unit must operate on 24 VAC
and utilize a switch which opens on humidity rise. Refer to the unit
wiring diagram for additional wiring details.
To install/connect a dehumidistat:
1. Turn OFF power to unit.
HIGH VOLTAGE
DISCONNECT ALL POWER BEFORE SERVICING
OR INSTALLING THIS UNIT. MULTIPLE POWER
SOURCES MAY BE PRESENT. FAILURE TO DO SO
MAY CAUSE PROPERTY DAMAGE, PERSONAL
INJURY OR DEATH.
2. To enable the dehumidify function, locate the ECM blower
motor interface module in the unit's blower section. Locate
the jumper labeled "HUM" on the interface module. Cut the
jumper to enable dehumidification (see ECM Blower Motor
Interface Module).
3. Connect "R" to the common side of the Dehumidistat (close
on humidity rise).

4. Connect the N/O (normally open) side of the Dehumidistat to
the HUM terminal on PCBEM103 ECM control board.
5. Turn ON power to unit.

Once the HUM jumper is cut at the ECM motor interface module,
the dehumidify function is enabled during a combination call for
cooling (T-Stat) and dehumidification (DEHUMStat).
