system. This requirement is necessary to ensure the accuracy of measurement.
Antifreeze protection. When external supply air water heater is used, it is necessary to properly install antifreeze protection from possible
freezing of heat carrier. Antifreeze temperature sensor (TV) must be mounted in clamp on return pipe of the water heater. Capillary sensor of the
