Itho Daalderop fault code S07
Fault code S07 on an Itho Daalderop heat pump (including HP-S) means: The flow temperature during heating / domestic hot water production is higher than permitted. The compressor is stopped if the flow temperature in heating or hot water mode is higher than 57 ℃. Reset the appliance once. If the code comes back, a part is usually faulty, often the compressor or inverter module.
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.
