Resideo T301920W0 Thermostatic Head
The Resideo T301920W0 Thera-6 Thermostatic Head is a high-performance hydronic control designed for contractors who require precision in challenging radiator placements. This self-actuating controller features a liquid-filled German sensor and a 6.6 ft (2.0 m) capillary remote sensor, making it the primary choice for radiators obstructed by furniture, curtains, or enclosures where internal sensing would be inaccurate. Built with a standard M30 x 1.5 connection, this head is fully compatible with V2000 and V100 radiator valves and serves as a direct, high-accuracy replacement for the legacy T100F1395 model.
Engineering-grade ASA thermoplastic construction ensures the handle resists yellowing and dust accumulation, while the internal high-strength structural ring provides the durability needed for heavy-duty commercial or residential use. With a temperature range of 34°F to 82°F and integrated frost protection, the T301920W0 maintains strict control accuracy per EN 215 standards. This compact thermostatic radiator valve head also includes setpoint limiting and blocking functions, allowing technicians to lock in efficient operating parameters and prevent end-user tampering.
Key Benefits- Remote Sensor Accuracy: The 6.6-foot capillary allows for remote temperature sensing, eliminating the "heat pocket" effect common in enclosed or covered radiator installations.
- Universal Compatibility: Fits standard M30 x 1.5 valve bodies used by Resideo, Honeywell Home, Braukmann, and MNG since 1974.
- Rugged Durability: Engineered with a high-strength plastic structural ring and non-yellowing ASA handle for long-term field reliability.
- Optimized Regulation: Liquid-filled sensing element provides high setting force and minimal hysteresis for consistent hydronic flow control.
- Visual Accessibility: Features embossed numbers and high-contrast markings specifically designed to assist visually impaired users with easy adjustments.
Is the T301920W0 compatible with Danfoss valves?
This specific model uses a standard M30 x 1.5 threaded connection. While it fits most modern hydronic valves, it is not a direct fit for Danfoss RA clip-on style valves without a separate adapter.
Can I install this on a vertical valve body?
Yes. Because this model utilizes a remote sensor, the orientation of the thermostatic head on the valve body (horizontal or vertical) will not negatively impact the temperature reading accuracy like it would with an internal sensor model.
Does this unit support frost protection?
Yes, the Thera-6 includes a frost protection setting, typically marked by the snowflake icon, which ensures the valve opens if the ambient temperature drops near freezing to prevent pipe bursts.
