What causes this fault?
This fault occurs when the boiler's internal computer is searching for a connection to a solar thermal system that it cannot find. The root cause is typically a settings error where the boiler has been told it is part of a solar setup, but the actual solar components are either missing, not yet switched on, or have lost their configuration data.
