vaillant vsmart

hi, i have a vsmart and ecotec 35watt boiler and now i have heating back on the heating curve has stayed at 0. the bungalow feels cold and i dont know if i have to reset the heating curve or if it'll do it itself. i try to let it sort itself out most of the time. it was new in a year ago

I doubt its a 35 watt more likely a 35 kilowatt. You will need to go into the menu system and change the heating curve yourself, it sets up how the heating will respond to the temperatures it measures and the demands made on it.

You should have made a note of the value, in case you needed to re-enter it.

that'll be the one i have - thank you.
i have always just let it do its own thing last byear but now noticed it is on 0 after summer switch off. if i reset it will it go to auto again or go through learning phase again

Vaillant details are scarce, but my impression is its a mix of you setting the heating curve value and tweaking it as you gain experience of how it responds and it seeming to do a little self teaching.

Its not even clear which bits of the kit, store what data.
