That's a new one on me - my Dad had a pellet stove installed in his last place, but the controller looked like some dead simple 1980s design. Is this so it can be controlled over the network?I repaired our boiler today, albeit temporarily. Vailant fault code "F75 Pump/water shortage"
It's happened a couple of times, a power cycle usually fixes it. But today when I was 60 miles away at a funeral, it didn't when my wife power cycled it.
I managed to get hold of our heating engineer when driving back from the funeral and he said that there's a pressure switch that gets gummed up and increasing the water pressure can help. There's sufficient pressure in the system to meet normal operation.
So topped the system up and it works, it's due a service so will get it sorted then. This is the back-up boiler, the primary boiler is a pellet boiler and the controller runs Linux and doesn't get past POST, so that's a job for later this week. I'll probably video the boot sequence as it's pretty quick and send it to the manufacturer in Austria.
