Installation

Important: Before installation, make sure that the product is only used for fan coil systems with 100-240V and meets the maximum current requirements (resistive 4A, inductive 3A, capacitive not support).

Installation Locations

It is necessary to select the installation locations for data source to collect the correct temperature and humidity data, and achieve the accurate control. The section will take internal data source as example to describe the best installation locations.

When using built-in sensors, it is suggested to install the thermostat about 5 ft. (1.5m) above the floor in an area with good air circulation at average temperature.
Note: If installation in an appropriate location is not possible, please select other data sources. For more info, click Data Source Selection.


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 interfaces;
  • The place where strong vibration may happen or easy to be subjected to physical shock.
