This listing is for a new old stock alpha ocean PCB to fit the 240e and 280e (please note not suitable for the 240p or 280p see my other listing for a new PCB for 1 of those) This is untested but has been dry stored and is still in box and packaging, if you’re looking for 1 you probably realise they’ve been obsolete for some time and when available were the best part of £300 so get a bargain to keep your trusty old boiler going a bit longer!!
