Rather than measuring temperature at the radiator itself, the ETRV works in a system with the ENGO E25 room thermostat, which measures true air temperature in the room from its wall-mounted position. The E25 thermostat sends commands to the ETRV heads to modulate the valve opening, achieving the setpoint temperature with a precision that a traditional manual TRV cannot match.\u003c\/p\u003e\n\n\u003cdiv class=\"engo-callout-blue\"\u003e\n  \u003cstrong\u003e⚠️ E25 Thermostat Required\u003c\/strong\u003e\u003cbr\u003e\n  The ETRV-M30+RA does NOT operate as a standalone device. It must be paired with an ENGO E25 room thermostat (sold separately) to function. One E25 can control up to 6 ETRV heads within the same room. The E25 may be wall-mounted (230V) or battery-powered, and can be used standalone (offline) or connected to the EGATE-PRO gateway for full app and voice control.\n\u003c\/div\u003e\n\n\u003cp\u003eThe head ships with both an M30×1.5 direct-fit adaptor and a Danfoss RA adaptor, making it suitable for the two most common UK TRV valve configurations without any additional accessories. Installation is straightforward: remove the old manual TRV head, screw on the ETRV, insert batteries, and follow the E25 pairing procedure. The ETRV then automatically calibrates to the valve insert pin height.\u003c\/p\u003e\n\n\u003cdiv class=\"engo-callout\"\u003e\n  \u003cstrong\u003e🪟 Open Window Detection — How It Works\u003c\/strong\u003e\u003cbr\u003e\n  The ETRV head's thermistor continuously monitors the local temperature at the radiator. If a sudden drop of 1.5°C is detected — typically caused by a window being opened — the head automatically closes the valve to avoid wasteful heating. After 15 minutes, the system assumes the window is closed and returns to normal temperature control. No manual reset required.\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eM30×1.5 thread — fits most UK and EU radiator TRV valve bodies\u003c\/li\u003e\n  \u003cli\u003eDanfoss RA adapter included — fits RA-type valve inserts\u003c\/li\u003e\n  \u003cli\u003eZigBee 3.0 and 868 MHz dual wireless communication\u003c\/li\u003e\n  \u003cli\u003eWorks with ENGO E25 thermostat controller (required — sold separately)\u003c\/li\u003e\n  \u003cli\u003eUp to 6 ETRV heads per E25 thermostat in a single room\u003c\/li\u003e\n  \u003cli\u003eBattery powered: 2×AA (not included)\u003c\/li\u003e\n  \u003cli\u003eAuto-calibration on first installation\u003c\/li\u003e\n  \u003cli\u003eOpen window detection — closes valve on 1.5°C drop, reopens after 15 minutes\u003c\/li\u003e\n  \u003cli\u003eFrost protection — activates automatically when valve is closed\u003c\/li\u003e\n  \u003cli\u003eVery quiet motorised operation\u003c\/li\u003e\n  \u003cli\u003eIP30 protection class\u003c\/li\u003e\n  \u003cli\u003eApp control and scheduling via ENGO Smart (requires EGATE-PRO gateway)\u003c\/li\u003e\n  \u003cli\u003eVoice control via Alexa and Google Assistant (with gateway)\u003c\/li\u003e\n  \u003cli\u003eTwo-way communication with E25 every few minutes\u003c\/li\u003e\n  \u003cli\u003eDimensions: Φ50 × 81 mm\u003c\/li\u003e\n  \u003cli\u003e5-year manufacturer's warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable class=\"engo-spec-table\"\u003e\n  \u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eETRV-M30+RA\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eThread Size\u003c\/td\u003e\n\u003ctd\u003eM30 × 1.5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eIncluded Adapter\u003c\/td\u003e\n\u003ctd\u003eDanfoss RA adapter\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003ePower Supply\u003c\/td\u003e\n\u003ctd\u003e2×AA 1.5V batteries (not included)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eCommunication\u003c\/td\u003e\n\u003ctd\u003eZigBee 3.0 (2.4 GHz) + 868 MHz RF\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eCompatible Controller\u003c\/td\u003e\n\u003ctd\u003eENGO E25 (required)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eMax Heads per E25\u003c\/td\u003e\n\u003ctd\u003e6 (per room)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eOpen Window Detection\u003c\/td\u003e\n\u003ctd\u003eYes — 1.5°C drop threshold, 15-min restore\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eFrost Protection\u003c\/td\u003e\n\u003ctd\u003eYes — automatic when valve closed\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eIP Class\u003c\/td\u003e\n\u003ctd\u003eIP30\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003eΦ50 × 81 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eColour\u003c\/td\u003e\n\u003ctd\u003eWhite\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eCompliance\u003c\/td\u003e\n\u003ctd\u003e2014\/53\/EU, 2011\/65\/EU\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e5 years\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eBefore fitting, check the valve type — use the M30 direct fit for standard M30×1.5 valves;
