NOTE − Do not bundle any excess 24VAC control wires inside
control box.
NOTE − Wire tie provides low voltage wire strain relief and to maintain
separation of field installed low and high voltage circuits.
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.
