An RV with multiple Furrion Chill air-conditioning zones uses an electronic ceiling controller for each rooftop unit and a shared multi-zone wall thermostat. Furrion's wiring diagram shows the separate rooftop supplies, the low-voltage communication cables and the DIP-switch assignments that distinguish the zones.

Confirm the correct system or model
The FACC12ESHA2-BL-AM enhanced multi-zone controller matches the FACW12ESZA2-BL-AM multi-zone thermostat for the documented R32 system. Each zone still requires an electronic air distribution box and appropriate rooftop unit. A single-zone controller is not automatically equivalent to the enhanced multi-zone control.
Furrion uses DIP 1 and DIP 2 to choose zone 1, 2, 3 or 4; DIP 4 addresses the furnace, and the system requires separate 12V and 115V supplies as shown. Only the appropriate furnace-control zone should be enabled. Keep the analog integration wires separate from the normal digital thermostat communication path. The stocked C-FACR15SA-A02 heat strip is described by Furrion for a manual ADB, so it is not recommended here as a general electronic upgrade.
