Line Voltage
• The line voltage to the unit should be supplied from a dedicated
branch circuit containing the correct fuse or circuit breaker
for the unit.
• An electrical disconnect must be located within sight
of and readily accessible to the unit . This switch shall be
capable of electrically de-energizing the outdoor unit. See unit
data label for proper incoming field wiring. Any other wiring
methods must be acceptable to authority having jurisdiction.
• Use only copper wire for the line voltage power supply to this
unit ( Table 3 (page 12) ). Use proper code agency listed
conduit and a conduit connector for connecting the supply
wires to the unit. Use of rain tight conduit is recommended.
• Provide power supply for the unit in accordance with Figure
13 (page 28) , Figure 14 (page 29) , and the units rating
plate.
• Overcurrent protection must be provided at the branch circuit
distribution panel and sized as shown on the unit rating label
and according to applicable local codes. See the unit rating
plate for maximum circuit ampacity and maximum overcurrent
protection limits.
• A wiring diagram is located on the inside cover of the control
access panel of the outdoor unit. The installer should become
familiar with the wiring diagram before making any electrical
connections to the outdoor unit. See
Figure 13
,
Figure 14
,
or the units rating plate.
• If any of the original wires supplied with the unit must be
replaced, they must be replaced with material of the same
gauge and temperature rating.
• Units are shipped from the factory wired for 240 volt
transformer operation. For 208V operation, remove the lead
from the transformer terminal marked 240V and connect it
to the terminal marked 208V.
• Connect the line-voltage leads to the terminals on the
contactor inside the control compartment.
Thermostat / Low Voltage Connections
• These Gas / Electric units are designed to operate with a
24 VAC Class II control circuit. The control circuit wiring
must comply with the current provisions of the NEC (ANSI/
NFPA 70) and with applicable local codes having jurisdiction.
Thermostat connections should be made in accordance with
the instructions supplied with the thermostat and the indoor
equipment.
• These units use a special 2 speed compressor to achieve a
high level of efficiency in a compact frame. A 2 stage cooling
/ 2 stage heating 24V thermostat should be used with this
unit. See
Figure 11 (page 27)
.
• The low voltage wires must be properly connected to the
units low voltage terminal block. Route 24V control wires
through the gas furnace side of the unit. Recommended wire
gauge and wire lengths for typical thermostat connections
are listed in
Table 4 (page 12)
.
• The thermostat should be mounted about 5 feet above the
floor on an inside wall. DO NOT install the thermostat on
an outside wall or any other location where its operation
may be adversely affected by radiant heat from fireplaces,
sunlight, or lighting fixtures, and convective heat from warm
air registers or electrical appliances. Refer to the thermostat
manufacturer’s instruction sheet for detailed mounting
information.
For 208Volt Operation Only:
• Units are shipped from the factory wired for 240 volt
transformer operation. For 208V operation, remove the lead
from the transformer terminal marked 240V and connect it
to the terminal marked 208V.
• The inducer motor low speed resistor must be by-passed
for 208 Volt operation. Remove the insulated quick connect
from one side of the resistor block and connect to piggyback
terminal on opposite side to complete motor circuit.
Heat / Cool Thermostat
2 Stage Heat / 2 Stage Cool Thermostat (Recommended):
For highest efficiency a 2 Stage Heating/Cooling thermostat
is recommended for this product. A 2 Stage Cool thermostat
is required for control of the special 2 speed compressor. A 2
Stage Heat thermostat will allow the gas heat to operate at a
more efficient low heat condition until there is a demand for
higher heat output to the conditioned space. See
Figure 11 .
Single Stage Heat / 2 Stage Cool Thermostat (Optional):
A 2 Stage Cool thermostat is required for control of the special
2 speed compressor. A single stage Heat thermostat can be
used in conjunction with the automatic heat staging jumper
on the ignition control board. The heat staging function will
automatically move the unit into high heat operation at the
time interval selected:
None = Low heat operation only, 5 = 5 minute delay from low
to high heat mode, and 10 = 10 minute delay from low to high
heat mode. See
Figure 12 (page 27)
.
Connect the Red, Yellow, Green, Blue, White, and Brown
(optional) low voltage thermostat wires to terminals R , Y1 (1st
Stage Cool), G , Y2 (2nd Stage Cool), W1 (1st Stage Heat), &
W2 (2nd Stage Heat-optional) on both the thermostat sub-base
and unit low voltage terminal board. The C terminal (Black wire),
is the 24V common wire required on some thermostat models.
See
Figure 13 , Figure 14 , or the units rating plate.
