Engo ETRV-M30 Wireless Electronic Radiator Head

Basic Information:

• Temperature measurement away from the radiator ensures comfort and resource savings.
• Very quiet operation.
• Simple, intuitive, and quick installation.
• Special algorithm ensures optimal temperature maintenance.
• Control via the ENGO Smart app through Gateway.
• Can operate offline without an internet gateway in 24-hour mode (without programming).
• Can operate in a group of up to 6 units in one room.
• Open window function: The ETRV automatically shuts off the flow to the radiator when it detects a sudden temperature drop of 1.5°C, indicating an open window. After 15 minutes, the system automatically restores normal heating control.

Features of Engo ETRV-M30:

The wireless ETRV radiator head for heating control requires connection to the main E25 controller. One controller can operate up to 6 ETRV heads in one room. Using an internet gateway, it is possible to control the set (valve + controller) via the ENGO Smart app.

The TRV head features a thermistor that detects sudden temperature drops (1.5°C), allowing automatic interruption of water flow when a window is opened, reducing heat losses. After 15 minutes, the system restores normal heating control, but if the window is closed earlier, the valve operation resumes immediately, increasing energy efficiency.

The E25 and ETRV set also works offline, allowing basic 24-hour control without the need for an internet connection, which is useful where programming is not required and operational reliability is a priority.
