Atlantic fault code 10
Fault code 10 on an Atlantic heat pump (including Indoor unit ALFEA EXCELLIA M DUO and IDU ALFEA EXTENSA DUO AI 10 R32) means: Outdoor temperature sensor: Short circuit. Sensor disconnected or switched off. Sensor defective. Other fault. Reset the appliance once. If the code comes back, a part is usually faulty, often a temperature sensor. You can check the water pressure and settings yourself; leave work on gas-carrying parts to a certified gas engineer.
After a safety alert (gas, flue gas, combustion), reset no more than once and call in a certified gas engineer. If you smell gas, call your national gas emergency number or 112 immediately.
