Furrion Chill Cube Wall Thermostat Wiring Diagram & Furnace Control

Use the wiring diagram for the exact thermostat, adapter and rooftop unit on their labels. For the identified aftermarket Chill Cube thermostat kit 2024047199, Lippert's CCD-0009478, revision 10.21.25, page 6 shows the thermostat terminals, and page 9 shows the adapter-to-thermostat harness. The four harness conductors carry DC power, ground and two communication signals; they are not four interchangeable furnace-control wires. The thermostat diagram labels the furnace return and ground separately.

The same kit manual's page 18 describes enabling supported heating equipment, including an available gas furnace. The ducted rooftop manual CCD-0009327, revision 08.25.26, page 9 also distinguishes wall-controller wiring from its model-specific furnace-switch connection. A harness label or a working AC connection alone does not confirm the furnace wiring, control type or configuration.

The question reports FACW13VSDA-BL but does not establish the full kit number, adapter revision or furnace interface. Our 2024047199 thermostat-kit listing is an identification reference, not proof that its wiring applies to that installation. Have a qualified RV technician match all component labels and the furnace documentation before connecting or changing wiring. Follow the matching manual's power-disconnection instructions; do not connect by wire color alone or assume that these references guarantee heating and cooling operation.
