Information Display
  • 3.5” TFT color LCD divided into two sections for better information display
  • The default screen displays the current temperature/humidity, temperature set-points, system mode, and schedule period
  • Display time, date and day of the week in a separate screen
  • The system working status and fan status are indicated in different backlit colors (Red for heat-on, Blue for cool-on, Green for fan-on)

 

Unique User Experience
  • Screen lights up for 20 seconds when motion is detected
  • Interactive wizard guides you through the quick setup without hassles
  • Intuitive and simple UI to ease the operation even without user’s manual
  • Smart rotary control wheel + 3 side-buttons for easy operation while adjusting temperature or navigating menus

 

Wireless Remote Control
  • Remote control using mobile APP by connecting to cloud server via Wi-Fi connection, allowing multiple thermostats to be accessed from single APP.
  • Complete technical document available to facilitate the integration with 3rd party platform
  • Over-the-Air firmware upgradable

 

Future Upgrades
  • Shows you the temperature/humidity outside or other indoor locations using remote temperature/humidity sensors
  • You could choose the onboard sensor temperature,any remote sensor temperature or the average temperature to be compared with set points temperature
  • Sends you notifications if the temperature gets too cold or too hot
  • Auto heat cut-off at or higher than 99°F (37°C); Auto heat cut-in at or lower than 39°F (4°C)
  • Equipped with both ZigBee Smart Energy and WiFi modules to interface with Smart Meter and Cloud Server at the same time
