      QAF21.6 | Landis & Gyr | Frost Protection Monitor / Temperature Sensor

      The Landis & Gyr QAF21.6 Frost Protection Monitor (Ref: 43540132123) is a temperature sensor designed to provide reliable frost protection for heating, ventilation, and air conditioning (HVAC) systems. It ensures system efficiency and safeguards against freezing conditions, making it ideal for use in industrial and commercial environments.

The QAF21.6 is a frost-protection / frost-monitor device designed to sense low air temperatures and trigger protective actions (e.g., heating, valve adjustments, shutting down systems) to prevent freezing or cold-related damage in HVAC, refrigeration, water-systems, and valve/actuator setups.

Frost/low-temperature detection using a 6 meter capillary-type sensing element for sensing air-side conditions. Adjustable flange and mounting options for ease of installation. Suitable for integration with HVAC systems, heating circuits, water or valve control systems that require frost protection Rugged build for industrial or marine-type environments (commonly used in marine & industrial thermostat/monitoring applications)
