Hello all (my apologies for doing this in English),
We moved into a house where the former owner left a Toon 1 on the wall. We're not with Eneco but it worked perfectly fine as a thermostaat last winter, letting us set up a 7 day program. But recently it reset itself and now hangs on the Eneco loading screen. I've tried several hard resets, including at adapter and boiler level, but it always freezes (usually on the third of the three squares). Interestingly, the central heating still works and seems to be following the last program (fallback memory in the boiler? Toon still communicating in the background?). Eneco tells me it's broken and I need a new thermostat. As a (mechanical) engineer, I find it difficult to believe it can't be fixed by re-installing a new software update (via the JTAG interface?). I'm not a programmer but would find it a shame to put it in the bin!
Any help/ideas would be most welcome. Thank you
