External NTC sensor 677200320

External temperature sensor for ventilation systems

This external NTC temperature sensor, manufactured by Zehnder, is a key component in controlling heat recovery ventilation systems, particularly in conjunction with ground heat exchangers (GHE). Its purpose is to precisely measure ambient temperature, enabling optimal operation of the heat recovery unit and efficient energy utilization.

This sensor is specifically designed for use with Zehnder ComfoAir 350/450/550 Luxe ventilation units. It allows the system’s operating parameters to adapt to current weather conditions, resulting in improved thermal comfort within the building and reduced operational costs.

• Precise measurement: Delivers accurate external temperature readings essential for correct ventilation system operation.
• Optimized GHE performance: Enables efficient use of heat stored in the ground, enhancing the overall efficiency of the ventilation system.
• Compatibility: Designed exclusively for integration with specific Zehnder heat recovery units (ComfoAir 350/450/550 Luxe), ensuring seamless system integration.
• Easy installation: Designed for outdoor mounting and connection via the Option Box module, simplifying integration with existing systems.

Note: This sensor requires connection through the Option Box module, which is not included in the package. Installers must ensure this component is available for proper system commissioning. The sensor guarantees reliable operation for a period of 2 years, backed by the manufacturer’s warranty.
