The CT100 can handle up to 2 stages of Pump compression and 2 stages of AUX heat.
STEP 1 - Connect O wire to the O terminal or B wire to the B terminal. This connects the change-over valve.
If you have both O and B - connect only the O wire to the O terminal and DO NOT connect B to B
terminal (see wire reference under Trane for B wire terminal).
STEP 2 - Connect the AUX 1, AUX 2, to the AUX 1 and 2 respectively.
This connects the auxiliary heat.
STEP 3 - Connect the Y and Y2 wires to the Y terminals.
This connects the compressor.
STEP 4 - Connect the R wire to RH terminal. This connects the power.
STEP 5 - Connect the G wire to G terminal. This connects the fan.
STEP 6 - Optional - Connect the C wire to the C terminal.
Your HVAC system is now connected to the CT100.
