The IVAR TE 3061 electrothermal head is commonly used in hydronic heating systems to regulate the flow of heated water through radiators or distribution units. It is typically installed in residential and commercial buildings where precise temperature control is required. Installers working with central heating systems will find this head suitable for integration with existing control circuits, particularly in systems that use 0-10V control signals. The head is designed for use in systems where the actuator or controller can provide a variable voltage signal to modulate the valve position, ensuring accurate and stable room temperature regulation.

As a normally closed (NC) device, the TE 3061 ensures that the valve remains shut in the absence of a control signal. This makes it ideal for applications where safety and energy efficiency are priorities. The head is often used in conjunction with thermostats, building management systems, or other control units that can generate a 0-10V output. The M30 x 1.5 thread allows for secure and leak-free connection to compatible valves and distributors.

The 0-10V control range allows for precise modulation of the valve position in response to temperature changes. The 24V supply voltage ensures compatibility with standard low-voltage heating system circuits. The normally closed configuration means the valve remains shut when no control signal is present, which is important for system safety and energy efficiency. These parameters are essential for proper sizing and selection to match the control system and valve type in use.

Installation and connection

Installation of the TE 3061 begins with verifying that the valve or distributor body is compatible with the M30 x 1.5 thread. The head is screwed onto the valve body and tightened to the manufacturer's recommended torque. Electrical connections must be made to the control system using the appropriate wiring, ensuring that the 24V supply and 0-10V control signals are correctly routed. It is important to confirm that the control system is configured to output the correct voltage range and that the polarity is correct to avoid damage to the head.

Common installation mistakes include incorrect thread alignment, which can lead to leaks, and incorrect wiring that may prevent the head from functioning. Installers should also ensure that the system is depressurised before fitting the head and that all electrical connections are made in accordance with local electrical codes and standards. A continuity check and voltage test should be performed after installation to confirm correct operation.

Compatibility and accessories

The TE 3061 is specifically designed for use with IVAR radiator valves and distributors of the following types: IVAR.CS 553, CI 557, UNIMIX, KS IVAR, and MULTIMIX-C. These valves must have an M30 x 1.5 thread to accept the head. No additional accessories are required for basic operation, but installers should ensure that the control system is compatible with 0-10V input signals. Related products include the listed IVAR valves and distributors, which must be ordered separately for system integration.

Technical background for designers

The TE 3061 operates by converting the 0-10V control signal into a mechanical movement that adjusts the valve position. The internal mechanism is designed to respond linearly to the voltage input, allowing for proportional control of the flow rate. The head is constructed from durable materials suitable for long-term exposure to heating system conditions. The normally closed configuration ensures that the valve remains shut in the absence of a control signal, which is important for system safety and energy efficiency. The integration of the head into the system depends on the control system's ability to provide a stable and accurate voltage signal, which affects the overall performance and efficiency of the heating system.

Service and operation

Regular visual inspections should be performed to check for signs of wear, corrosion, or leakage at the thread connection. The electrical connections should also be inspected for looseness or damage. No specific service intervals are provided in the technical data, but any malfunctioning or erratic operation should be investigated immediately. If the head fails to respond to control signals, the wiring and power supply should be checked. In the event of a leak, the system should be depressurised and the head re-tightened or replaced if necessary.

Frequently asked questions

Can the TE 3061 be connected to a 0-10V thermostat?
Yes, the TE 3061 is designed to accept a 0-10V control signal from compatible thermostats or control units. Ensure that the thermostat is configured to output within the 0-10V range and that the polarity is correct.

Is the TE 3061 compatible with all IVAR valves?
No, the TE 3061 is specifically compatible with IVAR.CS 553, CI 557, UNIMIX, KS IVAR, and MULTIMIX-C valves. It requires an M30 x 1.5 thread for installation.

Can the TE 3061 be used in a normally open configuration?
No, the TE 3061 is a normally closed (NC) device. It remains shut when no control signal is present. For a normally open configuration, a different model would be required.

What voltage is required to operate the TE 3061?
The TE 3061 requires a 24V supply voltage for operation. The control signal is a separate 0-10V input used to modulate the valve position.
