Installation Location

This section describes the recommended installation locations for the device to achieve accurate control.

Location for Temperature and Humidity

WT401 supports receiving ambient temperature and humidity data from either internal sensors or external servers/devices. When using internal sensors, it is important to choose appropriate installation locations to collect accurate environmental data and ensure accurate environmental monitoring and reliable control-setting input.

It is recommended to install the thermostat about 4-5 ft. (1.2-1.5m) above the floor, in an area with good air circulation at average temperature. If installation in an optimal location is not feasible, consider using external data sources.



Do not install the device where:
  • Close to hot or cold sources like hot or cold air ducts;
  • The place in direct sunlight;
  • Dead spots or drafts (behind the doors and in corners);
  • In areas that do not require conditioning;
  • Close to concealed chimneys or pipes;
  • Close to metal objects and large obstacles which affect the wireless transmission;
  • The place with lots of electromagnetic interference;
  • The place where strong vibration may happen or easy to be subjected to physical shock.

Location for Occupancy Detection

WT401 is equipped with a PIR sensor to provide motion-based occupancy detection to enable energy-saving feature.
Suitable Detection Area
The following table lists the recommended areas for occupancy detection.
Model Optimal Area Available Area
WT401 20 m² (4.2*4.8m) 40-50 m²
WT401-Flat-FL 35 m² (5.4*6.5 m) 70-80 m²

WT401-Flat-FL Reference: occupancy detection success rate in different areas within the detection range.



Suitable Installation Location
To ensure accurate detection, it is recommended that the device be positioned towards the primary activity areas of occupants within the room, such as the bed or desk in a hotel room. Do not install the device where:
  • Close to hot or cold sources like hot or cold air ducts;
  • The detection area contains moving objects such as waving trees or fans;
  • The view is blocked by curtains or barriers;
  • Facing a transparent surface (such as glass) within 6m (WT401) or 7m (WT401-Flat-FL).
