1. How to check
The above malfunction codes do not indicate a malfunction of the product. All you have to do is change the temperature suitably for
the limits shown in the manual. When the product malfunctions, if the actual situation does not match the above diagnosis, measure
the temperature of incoming air with S-net to see if the measurement is the same as the actual outdoor temperature. If not, replace
the temperature sensor.
