WIRING – LOW VOLTAGE WIRING
230/208V, 1 phase and 3 phase equipment 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 240V and 208V taps are:
TABLE 2
OPERATING VOLTAGE RANGE
TAP
RANGE
240V
253 – 216
208V
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).
An 18 gauge copper, color-coded thermostat cable is
recommended. The connection points are shown in this
Manual. See Table above.
Low Voltage Connection
These units use a grounded 24-volt AC low voltage
circuit.
“L” terminal is compressor lockout output. This
terminal is activated on a high or low pressure trip by the
electronic heat pump control. This is a 24 VAC output.
“W2” terminal is second stage heat (if equipped).
“O1” terminal is the ventilation input. This terminal
energizes any factory installed ventilation option.
“E” terminal is the emergency heat input. This terminal
energizes the emergency heat relay.
“W3” terminal is the dehumidification input. This
terminal energizes compressor, blower and three-way
valve.
