On the cold setting I think the bike is running too rich, it will almost idle off the mark in 1st gear with no throttle. I think I will just leave mine on the hot setting all year round.
No, it doesn't work like that, the target values are...
18F / 10C offset when switched to HOT (adds less fuel to map)
36F / 20C offset when switched to COLD (adds more fuel to map)
It doesn't matter if your display is set to show C or F these devices work the same, ie add the same percentage of fuel to the open loop map.
