NOTE − For proper voltages, select thermostat wire (control wires) gauge per table above.
NOTE − Do not bundle any excess 24VAC control wires inside control box.
ARun 24VAC control wires through cutout with grommet. B Run 24VAC control wires through wire tie.
C Make 24VAC control wire connections.
DTighten wire tie to security 24V control wiring.
NOTE − Wire tie provides low voltage wire strain relief and to maintain separation of field installed low and high voltage circuits.
DTIGHTEN WIRE TIE
Install low voltage wiring from outdoor to indoor unit and from thermostat to indoor unit as illustrated. See figures 14 and 15 for typical field connections when connecting unit to either a CBX32MV or CBX40UHV in non−communicating mode. For connections to other Lennox air handlers or furnaces, see the ComfortSense® 7000 installation instruction for further match component wiring illustrations.

NOTE − Any excess high voltage field wiring should be trimmed and secured away from any low voltage field wiring.
NOTE − To facilitate a conduit, a cutout is lo- cated in the bottom of the control box. Connect conduit to the control box using a proper con- duit fitting.
