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 Connection
These units use a 24-volt AC low voltage circuit.
The “R” terminal is the hot terminal and the “C”
terminal is grounded.
“G” terminal is the fan input.
“Y1” terminal is the compressor input.
“R” terminal is 24 VAC hot.
“C” terminal is 24 VAC grounded.
“A” terminal is the ventilation input. This terminal
energizes any factory or field installed vent option.
“W1” terminal is the heat input.
230/208 VOLT UNITS
All models are equipped with 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:
460 VOLT UNITS
All models are equipped with single primary voltage
transformers and no rewiring is required.

Direct Digital Controls (DDC)
For total and proper control using DDC, a total of 5
controlled outputs are required (4 if no ventilation is
installed).
LOW VOLTAGE CONNECTIONS FOR DDC CONTROL
Fan Only Energize G
Cooling Mode Energize G, Y1
Heating Mode Energize W1
Ventilation Energize G, A
