What you can check
On the Alféa Excellia / Excellia Duo (R410A split, 11-16, pre-A.I.)
- Check the heat pump isolator and consumer-unit breakers are on (do not open any casing).
- Note the error number/LED pattern shown and give it to your installer.
- If breakers trip repeatedly, leave the unit off and call an engineer.
