In the field of smart home and building automation, the demand for wireless and intelligent terminal temperature control is growing. With 19 years of accumulation of industrial communication technology, E-TOP has launched a multi-protocol wireless thermostatic radiator valve head (TRV) series, covering three mainstream wireless technologies: radio frequency (RF), Zigbee, and Bluetooth. With low power design, strong compatibility and precise temperature control capabilities, it provides wiring-free and easy-to-deploy intelligent temperature control solutions for residential, commercial, hotel and other scenarios, helping to achieve the green building goal of energy saving of 30%+.

Introduction to wireless thermostatic radiator valve head (TRV) product categories

Three core categories, accurately matching different wireless networking needs:
Radio frequency TRV (RF TRV)
Technical features: Control accuracy: ±0.5℃, built-in adaptive temperature compensation algorithm;
Power supply: 2 AA batteries, battery life ≥5 years (typical working conditions).
Application scenarios: Single-room temperature control in single-family houses and small apartments, suitable for wiring-free renovation of old buildings;
Form a point-to-point system with wireless thermostats (such as WT-25) to achieve low-cost intelligent heating.
Functional advantages: Plug and play, no gateway required, compatible with traditional radiators (G1/2″ threaded interface);
Supports manual override mode to meet temporary temperature adjustment needs;
Built-in anti-leakage protection mechanism, valve closing force ≥300N (EN 12186 standard).
Zigbee TRV
Power consumption management: sleep current <10μA, battery life ≥3 years (frequent communication scenario);
Extended functions: support linkage with door and window sensors, automatic valve closing when detecting window opening
Application scenarios: multi-zone networking control of large residential and hotel guest rooms, support centralized management of BA system;
Link with smart speakers (such as Amazon Alexa) to achieve voice control.
Functional advantages: support 7-day 4-time programming, automatically lower night temperature in energy-saving mode;
OTA firmware upgrade, remotely repair vulnerabilities or add new functions;
Comply with EU ErP directive, standby power consumption <0.3W.
Bluetooth TRV
Communication standard: Bluetooth 5.2, transmission distance 20 meters, support direct connection to mobile phones APP (no gateway required);
Interactive design: built-in LCD display, real-time display of room temperature, set temperature and battery status;
Security encryption: AES-128 data encryption to prevent illegal access.
Communication protocol: Bluetooth SIG Mesh (optional), compatible with Apple HomeKit and Google Home ecosystem.
Application scenarios: ready-to-use smart temperature control for rental apartments and short-term homestays, users can control it independently through mobile phones;
Temporary temperature control solutions for small offices and conference rooms, quick deployment without IT support.
Functional advantages: real-time monitoring by mobile phone APP, support for historical temperature curve query;
Geofence function: automatically switch to energy-saving mode when detecting users leaving home;
Support multi-user authority management, landlords can remotely set the upper temperature limit.

Core technical advantages – wireless interconnection, energy saving and efficiency improvement, safe and reliable
