Auber pid with timer

[gotbags-10]

So I'm wondering about this pid from auber. It has a built in timer. What I'm looking to do is get my HLT set up with water before hand like in the morning before work or a Friday night before I go to bed. Then have the pid kick on the element later on in the day or the middle of the night and come home or wake up to pre heated mash water.
