Safety thermostatic sensor - 1/2 "M IVAR.AC 634

Product detailed description

The safety thermostatic sensor is a critical component in hydronic heating systems, ensuring system integrity and occupant safety. It is commonly used in residential and commercial buildings with underfloor heating, radiant panels and manifold-based distribution systems. Installers and technicians integrate this device into manifold systems to monitor and control temperature thresholds, preventing overheating and damage to system components. The sensor is particularly relevant in systems where precise temperature regulation is essential for both efficiency and safety.

Correct installation and selection of this sensor are vital for the long-term performance of the heating system. It is typically mounted in close proximity to the manifold or heat emitter to provide accurate temperature feedback. The sensor operates in conjunction with control systems to trigger shutdowns or alarms when the set temperature limit is exceeded, thereby preventing system failure or damage to surrounding materials.

Technical parameters

Weight	0.103 kg
Code	580009
Brand	IVAR

The sensor is designed for 230 V operation and has a fixed trip point at +60 °C. These parameters are essential for system designers to ensure compatibility with the electrical and thermal requirements of the manifold system. The 1/2 inch male thread connection allows for secure and leak-free integration into the system. The trip point ensures that the sensor activates at a defined temperature threshold, providing consistent and reliable protection.

Installation and connection

The installation process begins with selecting the appropriate location near the manifold or heat emitter. The sensor is connected using a 1/2 inch male thread, which must be properly sealed with a suitable thread sealant or PTFE tape. It is important to ensure that the electrical connections are made in accordance with local electrical codes and that the sensor is securely mounted to prevent vibration-induced loosening. Common installation errors include incorrect thread sealing, which can lead to leaks, and improper electrical connections, which may cause malfunction or safety hazards. Installers should verify the alignment of the sensor with the system's control logic to ensure correct operation.

Compatibility and accessories

This sensor is specifically designed for use with IVAR DUAL, DUAL-MIX, COMBITOP and UNIMIX manifolds. It is not intended for use with other manifold types or systems unless confirmed by the manufacturer. No additional accessories are required for standard installation, but it is recommended to have sealing materials and electrical connectors on hand. When replacing or upgrading a system, it is important to ensure that the existing manifold and control system are compatible with the sensor's specifications.

Technical background for designers

The sensor operates using a bimetallic or electronic thermostatic mechanism that responds to temperature changes. When the set threshold of +60 °C is reached, the sensor triggers a shutdown or alarm signal to the control system. The materials used in the sensor's construction are selected for their durability and resistance to thermal cycling. The integration of the sensor into the manifold system allows for real-time temperature monitoring and rapid response to abnormal conditions. The sensor's performance is influenced by the thermal mass of the system, ambient conditions and the accuracy of the control system's response.

Service and operation

Routine service for this sensor is not required under normal operating conditions. However, periodic checks should be performed to ensure that the sensor is functioning correctly and that the electrical connections remain secure. Any signs of corrosion, mechanical damage or inconsistent temperature readings should be investigated. The sensor should be recalibrated or replaced if it fails to respond to temperature changes or if it triggers false alarms. No specific service intervals are provided in the technical data, but it is recommended to inspect the sensor during routine system maintenance.

Frequently asked questions

Can the sensor be used with manifolds other than DUAL, DUAL-MIX, COMBITOP and UNIMIX?
It is specifically designed for use with IVAR DUAL, DUAL-MIX, COMBITOP and UNIMIX manifolds. Use with other manifolds should be confirmed by the manufacturer.

Is the sensor suitable for use in high-temperature applications?
The sensor is designed to trigger at +60 °C and is not intended for use in systems that exceed this temperature threshold.

Can the sensor be adjusted to a different trip point?
The trip point is fixed at +60 °C and cannot be adjusted. It is not designed for user modification.

What type of electrical connection is required for the sensor?
The sensor operates on 230 V and requires a dedicated electrical connection in accordance with local electrical codes.
