Listed as a programmable touchscreen thermostat with a remote zone sensor. The original listing specifies a 24VAC system and requires a C-wire; confirm your system and the supplied wiring instructions before installation.
For systems without a C-wire, the original listing describes a power-module arrangement only with four wires W/W1, Y/Y1, G and R (or Rc/Rh), or three wires Y/Y1, G and R (or Rc/Rh). This does not establish support for every system without a C-wire.
The listing requires 2.4GHz Wi-Fi and states that 5GHz is not supported. It describes app scheduling and manual screen control; confirm the app and account requirements for the supplied version. Emergency heat is described only for heat-pump systems.
The zone sensor has a separate power supply. The original setup guidance specifies a distance of less than 3 metres for sensor data transfer; confirm placement and pairing in the supplied manual. This is distinct from the sensor motion-detection range.
