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

Product detailed description

Replacement actuators for three-way zone shutters are essential components in hydronic heating systems, particularly in multi-zone configurations where precise flow control is required. These actuators are typically installed in residential, commercial and industrial buildings with central heating systems. They are used to modulate the flow of heated water to individual zones, ensuring balanced thermal distribution and energy efficiency. Installers working on such systems must ensure compatibility with existing shutters and control systems to maintain system integrity and performance.

The actuator is commonly used in conjunction with thermostats and room controllers to automate zone-specific temperature regulation. It is installed in close proximity to the three-way zone shutter, with electrical and mechanical connections made according to the manufacturer's specifications. The actuator's response time and torque are critical for ensuring smooth and reliable operation under varying load conditions.

Technical parameters

Supply voltage	230 V
Code	I01420044
Brand	IVAR

The supply voltage of 230 V is standard for electrical actuators in central heating systems. The power consumption of 4 VA indicates a low-energy design, suitable for integration into standard electrical circuits. The rotation angle (90° or 180°) determines the actuator's range of motion and is selected based on the shutter's design and the system's flow requirements. The torque values (8 Nm or 28 Nm) define the actuator's ability to overcome resistance in the system, which is important for maintaining accurate flow control under different pressure conditions. The IP50 and IP55 ratings indicate the level of protection against dust and water ingress, depending on the installation orientation.

Installation and connection

The actuator is mounted directly onto the three-way zone shutter using the manufacturer's specified mounting points. The electrical connection is made via a standard 230 V supply line, with the actuator's wiring typically connected to a thermostat or control unit. The actuator's position must be aligned with the shutter's mechanical axis to ensure smooth operation. During installation, the actuator's orientation should be checked to ensure the correct IP rating is achieved. Common installation errors include misalignment of the actuator, incorrect wiring and failure to secure the mounting brackets properly. These can lead to reduced performance or mechanical failure over time.

Compatibility and accessories

This replacement actuator is compatible with MODULO 2 and MODULO 3 zone shutters. For older systems, the COMPACT 2 M and 3 M variants are recommended. No additional accessories are required for standard installation. The actuator is designed to integrate seamlessly with existing control systems, including thermostats and room controllers. It is important to verify the model number of the existing shutter to ensure correct compatibility before installation.

Technical background for designers

The actuator operates using an electric motor that converts electrical energy into rotational motion. This motion is transferred to the zone shutter via a mechanical linkage, allowing it to modulate the flow of heated water. The actuator is constructed from durable materials to withstand the operating conditions of central heating systems. The torque and rotation angle are key design parameters that influence the actuator's performance. The IP rating is determined by the installation position, with vertical mounting offering higher protection against water ingress. The actuator's response time and torque are critical for maintaining system stability and ensuring accurate temperature control.

Service and operation

The actuator requires minimal maintenance, with regular visual inspections recommended to check for signs of wear or damage. The electrical connections should be inspected for looseness or corrosion. The mechanical linkage should be checked for smooth operation and proper alignment. No specific service intervals are provided in the technical data, but any irregularities in operation should be addressed promptly to prevent system inefficiencies or failures.
