I have managed to figure this out myself, even the suggestion from Vaillant technical didn’t solve it! The boiler front panel CH flow temp value (which was set to 60 originally) has to be set HIGHER and acts as a max flow temp when using Vsmart through the ebus. Even though there is a Max CH...

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...

Just to report back, the settings recommended earlier have the house getting up to temperature quicker, maintaining a stable temp with less cycling thanks to changing the thermostats cycle rate. So thanks to all. I haven't adjusted the bypass as I wasn't sure where I stand on invalidating...

Will give it a look thanks

Ok thanks. Think I have been reading too many posts on here and getting obsessed with flow / return temps. Whatever happens, it's got to be more efficient than the circa 1994 boiler I left behind! Your are correct, as long as I am warm and temp is stable, job done. I think having the loud...

Ok thanks Bunnyman & The831Bunny for the settings info, will give them a try. Whilst appreciate what the boiler is trying to do, coupled with an room stat on/off control. I can't understand why there is alway this 5 minute delay, even if the heating circuit hasn't been used for a couple of...

Ok thanks the831Bunny. Is the 5 minute delay before burner modulation increases a software 'feature'. Do other users of ecotec plus models notice a similar delay when partial load has been set instead of being at 'auto'? I will try changing the setting you suggest and I am leaning towards...

Hello all, I have moved into my new house which has a Vaillant Ecotec Plus 832. DHW is fine but I just need to confirm the CH is behaving correctly as I couldn't see any other posts with this issue. The Honeywell CM907 wired room stat calls for heat, Boiler fires up, burner at full 2 seconds...
