P2 displayed; unit may limit operation or stop, especially in heating mode.

Steps:

• Check ambient conditions: Compare outdoor temperature with the minimum operating temperature in the Gorenje manual. If below spec, the unit may not operate reliably.
• Inspect outdoor sensor: Ensure the ambient sensor is correctly positioned and not influenced by direct sunlight or exhaust air.
• Wait and retry: When outdoor temperature rises, try operating again. If P2 appears even in normal temperatures, have the sensor and PCB checked by a technician.
