IMI thermostatic installation set BASE simple version, female 1/2" / male 1/2", BASE thermostatic head M30x1.5

The IMI thermostatic installation set BASE simple version combines a compact thermostatic head with M30x1.5 thread and matching female 1/2" and male 1/2" valve connections to provide automatic temperature control for radiator and convector circuits. Designed for both retrofit and new installations, this screw‑mounted set enables stable room temperature regulation by modulating flow through the radiator valve according to the thermostat setting. The construction is intended for straightforward mechanical installation where a small-profile thermostatic head is required.

Advantages

The set provides automatic, proportional control of radiator flow with a compact thermostatic head that suits confined installation spaces. The use of standard 1/2" female and male valve connections and an M30x1.5 threaded head ensures compatibility with many radiator valves and accessory heads. Installation is simple and quick when replacing existing thermostatic heads or fitting new valves, and the integrated design reduces the need for separate components.

Suitable for

• Temperature control of radiators and convectors in residential and small commercial heating systems
• Retrofit replacement of existing screw-mounted thermostatic heads
• New installations where a compact M30x1.5 thermostatic head is required
• Applications requiring standard 1/2" valve connections

When it may not be suitable

This simple version is intended for basic thermostatic control and may not include advanced features found in electronic or programmable thermostatic heads, such as timed temperature programs or remote connectivity. It may also be unsuitable where non-standard valve sizes or different thread types are required.

Key specifications

• Thermostatic head thread: M30x1.5
• Valve connections: female 1/2" and male 1/2"
• Application: radiator and convector temperature control
• Mounting type: screw-mounted thermostatic head

How to use

Mount the valve connections to the radiator or convector supply and return according to the installation instructions of the heating system. Screw the BASE thermostatic head onto the valve spindle with the M30x1.5 thread until secure. Adjust the thermostatic head to the desired room temperature setting; the head will automatically modulate valve flow to maintain that temperature. Follow standard commissioning procedures for balancing and bleed the radiator if necessary.

What to consider before purchase

• Ensure the radiator valve spindle accepts an M30x1.5 threaded thermostatic head
• Confirm that 1/2" female and male valve connections match your system plumbing
• Decide if a simple mechanical thermostatic head meets your control needs versus an electronic or programmable head

Usage recommendations

For reliable operation, install the set in accordance with local plumbing and heating codes, perform proper system flushing and balancing before commissioning, and avoid fitting the thermostatic head where it is exposed to direct drafts or heat sources that can affect temperature sensing.
