LOW VOLTAGE CONNECTIONS
The “R” terminal is the 24 VAC hot terminal and is supplied through Pin #10 of Plug P2.
The “C” terminal is the 24 VAC common/grounded terminal and feeds through Pin #11 of Plug P2.
The “G” terminal is the indoor blower input signal and feeds through Pin #6 of Plug P2.
The “Y1” terminal is the compressor starting signal and feeds through Pin #7 of Plug P2.
The “Y2” terminal is the compressor staging solenoid signal and feeds through Pin #4 of Plug P2.
The “O” terminal is the reversing valve signal and feeds through Pin #8 of Plug P2.
The “A” terminal is the ventilation demand signal and outputs a signal for ventilation during occupied programming conditions, and feeds through Pin #5 of Plug P2.
The “W2” terminal is the electric heat signal and feeds through Pin #9 of Plug P2.
The “W1/E” terminal is the emergency heat signal and feeds through Pin #3 of Plug P2.
The “L” terminal is used as an input terminal when a CS2000 infrared occupancy device is used. It feeds through Pin #12 of Plug P2.
The “D” terminal is used only of dehumidification models and feeds through Pin #1 of Plug P2.
