viessmann pcb

A long story short, basically a house stood empty for 7 years, boiler installed in loft but never commissioned. Attempted to fire it up and its coming up with an error code suggesting to change the PCB. Dillemma's

  1. Purchase new board and hope that any long term storage is confined here.
  2. Purchase new boiler and just accept that it is not viable to replace parts on an uncertain boiler albeit it is unused. The boiler is a top of the range with weather compensater fitted and is a condensing boiler.
  3. Hope that Raden comes along and says put the PCB on a radiator and it will sort itself out.

Merry Xmas all and Happy Nre Year.

Any sign of a backup battery on the PCB (for programmer or similar)? That would be shot after 7 years off power.

Desperate circumstances. Try the reset? See if PCB has battery (which has now discharged?) to hold NV settings?
