  • First panel heater with PID control heating technology. When desired temperature is reached, the heater will maintain this temperature by lowering the power level, resulting in a more stable heating with less fluctuation in temperature.
  • Predictive heating – the panel heater will heat the room so that the desired temperature is reached at a specific time. The heater learns how fast/slow the room goes up/down in temperature over time. That way, it will know when to start heating to achieve your desired temperature at the time you have scheduled in the app.
  • Seamless and easy connection with Bluetooth that automatically connects the device to your WiFi-network, regardless of the type of router you have
  • Silent operation due to silicon control – no clicking sound when the temperature goes up and down.
  • Child safety lock – for safe usage
  • Commercial lock for landlords
  • Open window function that switches off the heater automatically when a window is opened
  • Possibility to let Mill Sense override the heater´s temperature sensor – allowing more precise temperature control
  • OTA (Over the Air) updates allowing new exciting features to be added to the software
