Key Compatibility Notes
- UTB-TWC: Required for wireless control on the listed ducted indoor units.
- UTY-LRHYB1: Required for wireless control on the listed Cassette models.
- UTY-LBHXD: Required for wireless control on Circular Flow Cassette models.
- Polar 3-wire controllers: Cannot be connected to Circular Flow Cassette or Compact Floor models where specifically noted.
- AS*****GTAH wall-mounted units: Wired remote restrictions apply; check the exact model before selecting the controller.
Technician tip: Confirm the complete indoor model number before ordering or connecting a controller. Similar-looking indoor units can use different controller interfaces.
