TRV

ETRV-M28
Thermostatic Radiator Valve, M28x1,5, battery powered, white

Works in a set with the Internet temperature thermostat E25

  • • Measuring the temperature away from the heater provides comfort and savings
  • • Very quiet operation
  • • Simple, intuitive, fast installation
  • • Dedicated algorithm ensures optimal temperature maintenance
  • • Control from the ENGO Smart app via Gateway
  • • Can work in a group of up to 6pcs in 1 room
  • • 5 year warranty
  • • Open window function: ETRV automatically closes flow to the radiator when a sudden temperature drop of 1.5°C is detected, which indicates an open window. After 15 minutes, the system independently restores normal heating control.

    Wireless head for controlling radiator heating. In order for it to work properly, it is necessary to pair it with the E25 master controller. Up to 6 ETRV heads can be paired with a single thermostat in the same room. Using an Internet gateway, it is possible to control the set (head + thermostat) using the ENGO Smart app.

    The TRV head is equipped with a dedicated thermistor, which allows detection of sudden temperature drops, often associated with the opening of a window. If the sensor registers a temperature drop of 1.5°C, the system automatically closes the water flow to the radiator, preventing unnecessary energy consumption. After 15 minutes, which is considered a typical time of ventilation in winter, the head takes control of the heating again. However, if the window is closed earlier and the temperature difference decreases decreases, the TRV immediately returns to normal operation, minimizing heat loss and increasing the energy efficiency of the heating system. Thanks to this solution you can significantly save on heating costs, while at the same time taking care of the comfort of the user.

    E25 combined with ETRV offers offline operation without the need to connect to a web gateway, providing basic control on a daily cycle. Ideal for locations where schedules are not necessary and reliability of operation without internet access is crucial.
