Electrothermal head - 230V; no current open IVAR.TE 3050M

Product detailed description

Electrothermal heads are essential components in central heating systems, particularly in buildings with individual room temperature control. They are commonly used in residential, commercial, and industrial applications where precise regulation of heat distribution is required. Installers working with these systems typically deal with retrofitting or upgrading existing systems to improve efficiency and comfort. The IVAR TE 4040 is suited for integration into systems with radiator valves and distributors, where it can be used to automate temperature control based on electrical signals.

This model is particularly useful in systems where manual adjustment is impractical or where remote control is required. It is commonly found in systems with IVAR.CS 553, CI 557, UNIMIX, KS IVAR, MULTIMIX-C, BS EQUIMETER, and IVAR.SAT components. The electrothermal head ensures that the system can respond to temperature changes by opening or closing the valve as needed.

Technical parameters

Installation and connection

Installation of the IVAR TE 4040 requires careful attention to the connection thread, which is M30 x 1.5. This thread must be matched with the corresponding valve or distributor port. Before installation, verify that the valve or distributor is compatible with electrothermal heads. Common installation errors include incorrect thread engagement or failure to check the polarity of the electrical connection. Ensure the head is mounted in a position that allows free movement of the actuator and that the wiring is secured to avoid mechanical stress on the terminals.

Compatibility and accessories

The IVAR TE 4040 is compatible with a range of IVAR radiator valves and distributors, including the IVAR.CS 553, CI 557, UNIMIX, KS IVAR, MULTIMIX-C, BS EQUIMETER, and IVAR.SAT. When installing, ensure that the control system is capable of providing the required 230V signal. No additional accessories are required for basic operation, but installers should verify that the control wiring and terminal blocks are suitable for the intended application.

Technical background for designers

The electrothermal head operates by converting electrical energy into mechanical movement, which opens or closes the valve seat. The design uses a thermal actuator that responds to the presence or absence of electrical current. The materials used are selected for durability and resistance to thermal cycling. The integration into the system depends on the control logic—normally closed or normally open—determining the default state of the valve. The service life and efficiency are influenced by the quality of the electrical supply and the frequency of operation.

Service and operation

Regular inspection of the electrical connections and mechanical movement is recommended to ensure continued performance. No scheduled service intervals are specified in the technical data. Checkpoints include verifying that the head responds correctly to control signals and that there is no mechanical binding or corrosion affecting the actuator. If the head fails to respond, check the wiring and power supply before replacing the unit.

Frequently asked questions

Can the IVAR TE 4040 be used with a 24V control system?
No, the TE 4040 requires a 230V supply and is not compatible with 24V control systems.

Is the TE 4040 suitable for use with thermostatic radiator valves?
Yes, it is compatible with thermostatic and manual valves as long as the connection thread and control logic match.

Can the head be used in normally open configuration?
Yes, the TE 4040 is available in both normally closed and normally open configurations.

What is the maximum operating temperature for the TE 4040?
Refer to the manufacturer's technical data sheet for the full range of operating conditions.
