2. Route the previously run AC power supply line through the Romex Connector and into relay control junction box.
3. Connect the white to white; black to black; and green to green or bare copper wire using appropriate sized twist wire
connectors. Tape the twist wire connectors to the supply wiring to assure they do not vibrate off.
4. Tighten screws on Romex connector being careful not to pinch and cut into the insulation on power supply leads.
5. Push excess wires into junction box. Install junction box cover. See FIG. 11 and 15B.
B. CONNECTION OF LOW VOLTAGE WIRES
1. Connect the previously run +12VDC to the red wire labeled +12V protruding from the air conditioner (Do not connect
wires if using the 3308120.XXX Genesis Air Filtration System).
2. Connect the previously run -12VDC to the black wire labeled -12V protruding from the air conditioner (Do not connect
wires if using the 3308120.XXX Genesis Air Filtration System).
3. Connect the two (2) blue wires from the air conditioner to the furnace leads (if applicable). Polarity does not need to be
observed on the furnace leads.
4. Connect the air conditioner yellow wire to the EMS wires (if applicable). Do not allow the yellow wires to short out or
touch, because the compressor will fail to run.
5. Connect the Comfort Control Center
the control cable leads out of the air conditioner. Either one of the two (2) control cables can be used.
6. Connect the remote temperature sensor lead into the remote sensor extension from the air conditioner (if applicable).

cable leads out of the air conditioner for the next zone (if applicable).

Check the alignment to ensure level installation.
3. Install the previously terminated 4-conductor control cable RJ-11 connector into the back of the CCC. Gently press the
CCC onto the base plate.
