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).

16. WIRING – LOW VOLTAGE WIRING
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
.
“Y” terminal is the
economizer input (where equipped)
.
“Y1” terminal is the
compressor input
.
“Y2” terminal is the
compressor staging solenoid input
.
“R” terminal is 24
VAC hot
.
“C” terminal is 24
VAC grounded
.
“F” terminal is the
ventilation input
. This terminal
energizes any factory or field installed vent option.
“2” terminal is the
alarm output
.
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.
