Duration of stand-alone heating

Hi guys ! I’m still quite new here and have my V70 only since 6 weeks, but is really a great forum here. I know that you don’t need sand heating in this weather but you are curious. And try everything out. Now I was told that there are two different times of webosto 30min and 60min that you can see through the display lighting of the timer. green=30min red=60min runtime. Does one of you know if you can change this at the timer k ann (because in the description there is no hint) or whether you have to get a new watch with longer programming times ? Greeting Moods
