Everything fine here ...

I thought that might be the problem, but where would I put
high portA.0

If I put it before the mainloop it displays the temperature all the time,
if I put it at the end of mainloop then it still displays the * and stays on set temperature.

I can't figure out where to put it, must be easy but I just cant see it.
