I have a Vaillant V Smart controlling my 832 ecotec combi boiler.
Just recently, the CH flow temp has been stuck at 60 degrees as set on the front panel, ignoring the Vsmart flow temp from ebus D.009 which goes up and down as the compensator should.
The vsmart is working, recognised in the settings and the target values change in D.009. The house isn’t hitting the prediction targets as well as before because it seems to have lost the ability to alter the target temp.
Any ideas?
Thanks
