▶FAQ:
Q：Does it work with North American HVAC systems?
A：Yes, it supports North American 24VAC systems: 2H/2C conventional (gas/electric/oil) and 4H/2C heat pumps, plus dual-fuel setups .
Q：Need a C-Wire? What if my building doesn’t have one?
A：If you have R, Y, and G wires, you can use the C wire adapter (SWB511) to supply power to the thermostat when there is no C wire.
Q：Can we manage multiple units (e.g., hotel) from one platform?
A：Yes. The Tuya APP lets you group, bulk-adjust, and monitor all thermostats centrally .
Q：Is there API integration for our BMS/property software?
A：It supports Tuya’s MQTT/cloud API for seamless integration with North American BMS tools
Q：Supports remote zone sensors? How many?
A：Up to 16 remote zone sensors to balance hot/cold spots across large spaces (e.g., offices, hotels) .
