Sounds like a huge advantage over eberspacher that seem to have a 4 degree tolerance which is quite a big range for something that is supposed to be able to maintain a stable temperature, open source is an interesting twist too as it means it will only get better, downside of that is it can get overly complicated as too many nerds get involved.
With ebers a lot of folk say to run flat out and open windows accordingly to avoid coking of the burner, with the chinese ones it's probably cheaper to replace when coked anyway, that said I run my eber to the temp controller letting it idle and it's been fine for the last 4 years.
