Get dependable cooling with a complete AC system designed for multi zone control. Kits include the rooftop unit, distribution box, controller, and wall thermostat, so full replacements on ducted setups are straightforward. A smart pick when updating older gear that uses different refrigerants, and flexible enough to run a single zone now and add more zones later.
Yes, but plan on a full system replacement. New AC units use R32 refrigerant and are not backwards compatible with older AC systems. Verify your RV uses a typical ceiling distribution box and ducted layout. You'll install the new rooftop unit, controller, distribution box, and wall thermostat instead of reusing the old controls.
Room temperature is often sensed at the air distribution box intake, not the wall thermostat. This has worked well in ducted installs. If you notice short cycling in an unducted setup, consider a sensor relocation kit. If controlling a furnace, confirm the controller's DIP setting for heat and that the thermostat wiring is landed correctly.
Expect a heavy rooftop lift and have help or a lift tool ready. Directions are helpful, but take time to map wiring and zone settings. Pull the shipping foam divider and install it between the unit and distribution box. Mount the wall thermostat and route its wire as needed. Double-check DIP switches, including furnace enable if used.
Yes, Multi Zone can run a single zone. Confirm DIP switch settings in the controller per the manual when using fewer zones. Check thermostat wiring too—some systems use a four-wire connection, so if you're replacing a three-wire thermostat, make sure you have a spare conductor available.
