All equipment leaves the factory wired on 40V tap. For 08V operation, reconnect from 40V to 08V tap. The acceptable operating voltage range for the 40V and 08V taps are: TABLE OPEATIN VOLTAE ANE TAP ANE 40V 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). An 8 gauge copper, color-coded thermostat cable is recommended. The connection points are shown in this Manual. See Table below. Low Voltage onnection These units use a 4-volt A low voltage circuit. The terminal is the hot terminal and the terminal is grounded. terminal is the fan input. Y terminal is the compressor input for cooling. 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. 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.
