What causes this fault?

This fault occurs when the electrical connection to your outdoor temperature sensor is interrupted by a short circuit. The most common reasons are water getting into the sensor housing or the external wiring being accidentally damaged or pinched against the wall.

This issue is more frequent during periods of heavy rain or driving wind, which can force moisture into electrical connections that aren't perfectly sealed.
