Replacement actuator for three-way zone shutter MODULO IVAR.MODULO PLUS 3

Product detailed description

Replacement actuators for three-way zone shutters are essential components in central heating systems, particularly in multi-zone installations where individual room temperature control is required. These actuators are commonly used in residential and commercial buildings, including apartment blocks and office complexes. Installers typically work with these devices in conjunction with thermostats and control systems to regulate the flow of heating media through the system. The actuator must be correctly matched to the zone shutter model and system requirements to ensure accurate and reliable operation.

When replacing an actuator, it is important to consider the mechanical and electrical specifications of the existing system. The actuator must be compatible with the zone shutter model and the control system in use. This ensures that the actuator can respond correctly to control signals and maintain the desired level of system performance. The installation process typically involves disconnecting the old actuator, connecting the new one, and verifying the operation of the system.

Technical parameters

Supply voltage	230 V
Code	I01420172
Brand	IVAR

The supply voltage of 230 V is standard for many electrical systems in Europe. The power consumption of 4 VA is relatively low, indicating that the actuator is energy-efficient. The IP50 and IP55 ratings refer to the protection against dust and water, depending on the mounting orientation. These ratings are important for determining the suitability of the actuator for different installation environments. The torque values of 8 Nm and 28 Nm indicate the force available to operate the zone shutter, which is essential for ensuring proper flow control.

Installation and connection

Installation of the replacement actuator requires careful attention to the mechanical and electrical connections. The actuator is typically connected to the zone shutter using a mechanical linkage or direct coupling. The electrical connections must be made to the control system, ensuring that the wiring is correct and secure. It is important to verify the mounting orientation to determine the appropriate IP rating for the installation location. Common installation mistakes include incorrect wiring, improper mechanical alignment, and failure to check the operating angle of the actuator. These errors can lead to reduced system performance or complete failure of the actuator to function correctly.

Compatibility and accessories

This replacement actuator is compatible with MODULO COMPACT 2, PLUS 2, COMPACT 3, and PLUS 3 zone shutters. For older MODULO 2 and MODULO 3 models, the COMPACT 2 M and 3 M variants are recommended. When replacing the actuator, it is important to ensure that the new model is compatible with the existing control system and wiring configuration. No additional accessories are required for standard installations, but it is always advisable to verify the compatibility of the actuator with the specific system in use.

Technical background for designers

The actuator operates by converting electrical energy into mechanical motion, which is used to control the position of the zone shutter. The motor is designed to provide a specific torque output, which is essential for ensuring that the shutter can be opened and closed with the required force. The materials used in the construction of the actuator are selected to provide durability and resistance to environmental factors such as dust and moisture. The integration of the actuator into the system depends on the control signals it receives, which determine the position of the shutter. The service life and efficiency of the actuator are influenced by factors such as the operating environment, the frequency of use, and the quality of the installation.

Service and operation

Regular inspection of the actuator is recommended to ensure that it continues to operate correctly. This includes checking the mechanical connections for wear or damage and verifying the electrical connections for continuity. The actuator should be tested periodically to confirm that it responds correctly to control signals. No specific service intervals are provided in the technical data, but it is advisable to perform routine checks as part of the overall system maintenance.

Frequently asked questions

Can the actuator be used with older MODULO 2 and MODULO 3 models?
Yes, the COMPACT 2 M and 3 M variants are compatible with older MODULO 2 and MODULO 3 models. These variants provide the same functionality as the standard COMPACT and PLUS models.

What is the difference between the COMPACT and PLUS variants?
The COMPACT variants have a rotation angle of 90° and a time constant of 60 s, while the PLUS variants have a rotation angle of 180° and a time constant of 120 s. The PLUS variants are suitable for applications where a larger range of motion is required.

How does the IP rating affect the installation?
The IP rating depends on the mounting orientation of the actuator. IP50 provides protection against dust, while IP55 provides additional protection against water jets. This means that the actuator can be installed in different environments depending on the level of protection required.

What should be checked during installation?
During installation, it is important to check the mechanical alignment of the actuator with the zone shutter, verify the electrical connections, and confirm the mounting orientation to determine the appropriate IP rating. These checks help to ensure that the actuator operates correctly and safely.
