LOW VOLTAGE CONNECTIONS

These units use a grounded 24 volt AC low voltage circuit.

The “R” terminal is the hot terminal and the “C” terminal is grounded.

“G” terminal or pins 6 and 1 of P2 are the fan inputs. Both must be energized for proper fan operation. This is done automatically in the factory installed climate control options. If the climate control option is abandoned and connections are made directly to P2 both pins 6 and 1 of P2 must be energized for proper operation.

“Y” terminal or pin 7 of P2 is the first stage cooling input.

“B” terminal or pin 8 of P2 is the first stage heating input.

“R” terminal or pin 10 of P2 is 24 VAC hot.

“C” terminal or pin 11 of P2 is 24 VAC grounded.

“L” terminal or pin 12 of P2 is the second stage cooling input.

“W2” terminal or pin 9 of P2 is second stage heating output.

“O1” terminal of pin 5 of P2 is the ventilation input. This terminal energizes any factory installed ventilation option.
