Hi, some help needed please.
I have a Vaillant system: VRC470/VR61/Ecotech plus 24 / Vaillant cylinder.
Configured for two heating circuits radiators upstairs and UFH downstairs.
All worked fine until yesterday, DHW temperature was around 45 oC, then for some reason water temp dropped to 36-38 oC, heating seems working fine though.
It still shows desired water temp. 45 but not heating and under status VRC470 shows Cylinder "not charg.". I tried to change from Auto to Day, also restarted boiler with on/off button - nothing helps. Also tried Cylinder boost setting - no results whatsoever.
Seems like for whatever reason it doesn't want to heat DHW in the cylinder
Any ideas what this may be? any suggestion appreciated
Thanks
