WIRING – LOW VOLTAGE WIRING
“W2” terminal is second stage heat (if equipped).
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:
“O1” terminal is the ventilation input. This terminal energizes any factory installed ventilation option.
TABLE 2
“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. 1
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.
