Hi I’m new to this controller and all it came with is the simple manual. Can anybody explain the daily timer settings or have a link to the detailed manual?

I just need to set up the timer but on the settings under daily timer it has setting 1 & setting 2 which I have no idea how to set or the purpose of it?

Also does this controller have any nightly frost protection settings? All I can see is a night setting but the minimum temperature is +17.

Any help will be much appreciated.
Thanks
