Hi All,
I recently just completed my first installation of a Vaillant AroTherm Plus 7kw ASHP and just noticed that there is an F70 fault on the VWZ AI controller unit?
This is a common issue for Vaillant boilers that need to have a Designated System Number setup. Is this also the case for the AroTherm plus 7kw?
Where in the installers menu does this get configured?
I hope someone can assist?
