Anti-freeze Module Heiztechnik HT CVA212

The Anti-freeze Module Heiztechnik HT CVA212 is a temperature-control device designed to prevent freezing in heating systems and related components. It continuously monitors system temperature and activates built-in heating or circulation outputs when temperatures approach the set threshold, helping to protect pipes, heat exchangers, boilers and pumps from cold-induced damage. Intended for residential and light-commercial heating circuits, the module offers automatic frost protection and straightforward integration into existing installations.

Advantages

The module provides automated frost protection by responding to low-temperature conditions without the need for manual intervention. Compact and focused on function, it reduces the risk of burst pipes and component failure by initiating heating or circulation when required. Its design allows compatibility with common heating circuits and control architectures, enabling reliable, consistent operation in seasonal cold conditions.

Suitable for

• Residential central heating systems requiring frost protection
• Light-commercial heating circuits in small offices or shops
• Protection of boilers, circulation pumps and exposed piping
• Integration into systems where automatic temperature-triggered control is needed

Key specifications

• Function: temperature monitoring with automatic activation of heating or circulation
• Application: frost protection for heating circuits and components
• Installation: in-line mounting within heating circuit electrical/control panels or nearby junctions
• Outputs: control signals for heating elements or circulation pumps (electrical switching)
• Operating environment: designed for indoor heating system installations in residential and light-commercial settings

How to use

Install the anti-freeze module in accordance with local electrical codes and the system manufacturer’s wiring practices, positioning it where it can accurately sense circuit temperature. Connect the module’s temperature sensor or sensing input to the pipe or ambient location specified for reliable detection. Wire the control outputs to the designated heating element or pump circuit so that the module will switch them on when the measured temperature falls below the configured threshold. Commission the unit by verifying sensor placement, setting the activation temperature if adjustable, and testing the switching action under controlled conditions.

Usage recommendations

For reliable protection, place the sensor on a representative section of pipework or in the area most exposed to cold drafts. Verify electrical connections and protections (fuses, contactors) match the controlled device ratings. Periodically test the module before and during the cold season to confirm proper activation and replace any components showing wear or corrosion.
