TRANSFORMER TAPS
230/208V, 1 phase and 3 phase equipment employ dual
primary voltage transformers. All equipment leaves the
factory wired on 240V tap. For 208V operation, reconnect
from 240V to 208V tap. The acceptable operating voltage
range for the 240 and 208V taps are:
TAP RANGE
240 253 – 216
208 220 – 187
NOTE: The voltage should be measured at the field power
connection point in the unit and while the unit is
operating at full load (maximum amperage
operating condition).
WIRING – MAIN POWER
Refer to the unit rating plate for wire sizing information and
maximum fuse size. Each outdoor unit is marked with a
“Minimum Circuit Ampacity”. This means that the field
wiring used must be sized to carry that amount of current. If
field installed heaters are added to the basic unit, a second
separate power supply circuit will be required. The heater
rating plate located adjacent to the basic unit rating plate
will show the appropriate circuit ampacity fuse size, etc.
(Also see “Electrical Data” on pages 2 and 3.) All models
are suitable for connection with copper wire only. These
instructions must be adhered to. Refer to the National
Electrical Code for complete current carrying capacity data
on the various insulation grades of wiring material.
The electrical specifications on page 2 and 3 lists fuse and
wire sizes (75°F copper) for all models including the most
commonly used heater sizes.
The unit rating plate lists a “Maximum Time Delay Fuse” or
“HACR” type circuit breaker that is to be used with the
equipment. The correct size must be used for proper circuit
protection and also to assure that there will be no nuisance
tripping due to the momentary high starting current of the
compressor.
WIRING – 24V LOW VOLTAGE CONTROL
CIRCUIT
Five (5) wires should be run from thermostat subbase to the
24V terminal board in the unit. A five conductor, 18 gauge
copper, color-coded thermostat cable is recommended. The
connection points are shown in Figure 8.
THERMOSTATS
See specific wiring information for the different models, heater KWs, and voltages on pages 14 through 18.
TABLE 7
WALL THERMOSTAT and SUBBASE COMBINATIONS
IMPORTANT NOTE: Only the thermostat and subbase combinations as shown above will work with this equipment. The
thermostat and subbase MUST be matched, and correct operation can be assured only by proper selection and
application of these parts.
Q
R
No automatic changeover position – must be manually placed in heat or cool. Reversing valve
remains energized at all times system switch is in heat position (except during defrost cycle). No
pressure equalization noise when thermostat is satisfied on either heating or cooling.
Allows thermostat to control both heating and cooling operation when set in “AUTO” position.
Reversing valve de-energizes at end of each “ON” heating cycle.
