I think "froling" is a swear word, and a P4 is a Pentium 4?

It's apparently a wood pellet fired boiler. It comes with a microprocessor control system which can be externally controlled over serial or bus, presumably by some proprietary protocol. Would likely need some reverse engineering to figure it out. It looks though as there are already plenty of options from the manufacturer for remote control - where does the arduino come in?
