My mistake I have DS18B20s. I basically drag and dropped your code in and it does seem to work very well, short of it is only pulling the first temp. The parasitic temps are not returning proper values.
My sketch is constantly displaying the current temps and the buttons change the pages of the menu. Previously the menu buttons would fail to do anything, assuming due to the conversion time, but now buttons work every time. So that is really good, just need to tweak it so that the other temps are displayed properly.
