How do you use the scheduler for different slider outputs

I have 2 Pocket Powerbox Advance Gen2 units both new within 6 months. Bye the way, both work great. One unit has firmware 2.8 and the other is at 2.6. How do I get the unit with 2.6 upto 2.8?

Can you add an option in the GUI to display temp in Deg F. Right now it only can be displayed in Deg C.
