For 08V operation, reconnect from 0V to 08V tap. The acceptable operating voltage range for the 0V and 08V taps are: n 8 gauge copper, color-coded thermostat cable is recommended. The connection points are shown in this Manual. See Table below. TBLE OPETIN VOLTE NE TP NE 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 low voltage circuit. The terminal is the hot terminal and the terminal is grounded. terminal is the fan input.

W terminal is the nd stage heat (if equipped). terminal is the ventilation input. This terminal energizes any factory installed ventilation option. terminal is the dehumidification input. If installed, this terminal energizes any factory installed dehumidification option. NOTE: On models with J or M ontrol Module, terminal is used along with and for the alarm relay. J or M modules are not used in conjunction with dehumidification units.
