The “P1” code on your Leone Pro indicates that the unit has entered its auto-defrost mode, which can occur when the ambient room temperature drops.
This is a normal self-protection feature designed to prevent ice buildup on the coils.
The Leone Pro is designed to operate within a temperature range of 5°C to 35°C.
Even if the room temperature is not significantly below 18°C, the unit may still enter auto-defrost mode depending on the environmental conditions.
In this case, we recommend allowing the unit to complete the defrost cycle, after which it should automatically resume normal operation.
