Thermostatic sensor Danfoss REGUS M30 015G3630 — M30 thread, room temperature control

Danfoss REGUS M30 015G3630 thermostatic sensor with M30 thread is designed to measure room temperature and provide reliable feedback to compatible thermostatic valves in heating systems. The compact sensor detects ambient conditions and transmits a proportional signal through the valve mechanism to regulate radiator or manifold flow. Its construction suits residential and light commercial installations where accurate room temperature control is required.

Advantages

The sensor offers precise temperature sensing with a mechanical design that integrates directly into M30-threaded thermostatic valve bodies. It supports stable room climate management without electronic components, which reduces complexity and maintenance. The device's compact form factor allows installation in confined spaces and on a variety of radiator and manifold fittings. Materials and build quality are intended for long-term operation in heating circuits.

Suitable for

• Room temperature control on radiator thermostatic valves with M30 thread
• Hydronic underfloor heating manifolds requiring manual thermostatic sensing
• Residential apartments, single-family homes and small commercial premises

Key specifications

• Thread type: M30 mounting thread compatible with standard thermostatic valve bodies
• Function: Ambient room temperature sensing for hydraulic valve actuation
• Construction: Compact mechanical sensor element designed for heating system environments
• Compatibility: Intended for use with thermostatic radiator valves and manifold valves accepting M30 sensors
• Application: Suitable for radiators and underfloor heating manifolds in closed heating circuits

How to use

Install the thermostatic sensor by screwing it into the M30-threaded valve body until secure, ensuring the sensor bulb or sensing element is exposed to ambient air rather than directly in contact with heated surfaces. After mechanical installation, set the paired thermostatic valve according to system balancing and desired room temperature. The sensor operates passively, converting ambient temperature changes into valve position adjustments; no additional wiring or power supply is required. Verify correct operation by observing valve response while changing the room thermostat setting or by manually adjusting the valve.

Usage recommendations

Mount the sensor at representative room height, away from direct sunlight, drafts, or heat sources, to ensure accurate ambient temperature measurement. Periodically inspect for mechanical damage or corrosion and ensure the valve body threads are clean before installation. When replacing an existing sensor, confirm compatibility with the valve body thread and design to maintain system performance.
