To prevent the heating coil from freezing, a QAF65.6AR-J frost monitoring switch is installed, which in the cooling mode in the hot seasons of the year, its tube is exposed to water spraying. Is there any problem with it? Attachment 1700640693236.jpg (563 Downloads)

The IP (ingress protection) class provides this information. The QAF65.6AR IP is 65 rated. The meaning of the second number “5” is: “water projected by a nozzle (6.3 mm (0.25 in)) against enclosure from any direction shall have no harmful effects”. This means that the sensor is suitable for your application. For more information about IP protection code you may look under: https://en.wikipedia.org/wiki/IP_code Best regards, Albis
