All equipment leaves the factory wired on 0V tap. For 08V operation, reconnect from 0V to 08V tap. The acceptable operating voltage range for the 0V and 08V taps are: An 8 gauge copper, color-coded thermostat cable is recommended. The connection points are shown in this Manual. See Table below. TABLE OPERATING VOLTAGE RANGE TAP RANGE 0V V 0 87 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). Low Voltage onnection These units use a -volt A low voltage circuit. The R terminal is the hot terminal and the terminal is grounded. G terminal is the fan input. Y terminal is the compressor input for cooling -Stage units only or -Stage units with EONWM* Pink Wire is nd Stage cooling -Stage units only with EONWM* Y terminal is the st Stage compressor input for cooling -Stage units only No EONWM* Y terminal is the nd Stage compressor input for cooling -Stage units only No EONWM* W terminal is the st stage electric heat. W terminal is the nd stage heat (if equipped). A terminal is the ventilation input. This terminal energizes any factory installed ventilation option. D terminal is the dehumidification input. If installed, this terminal energizes any factory installed dehumidification option.
