How to switch comfort mode off on a Valliant ecoTec pro28.
only found instructions on how to do it on different models and not this one.
Please see attachment. I have the following buttons: turn off flame, Info, - (minus), and +(plus).
Thanks you.

Turn hot water temp right down to min until light goes off then back to set temp.
To turn on again go right to max and then set desired temp
