So I just got my flexwatt/thermostat in the mail. I'm stoked. But I have a FEW questions that should be 100% commonsense...but I do not, under any circumstances, want to take ANY chances, so I'm asking them here.

1.) Flexwatt should be applied ribbed side up, correct(I can feel the grooves barely with my fingernails)?

2.) I bought foiltape to hold the Flexwatt in place. Should I just tape it down at the edges, or cover all of it?

3.) While reading the instructions for setting up the Thermostat, I admit I was having a few :|9 moments.

First, I set it to F, obviously. For the setpoint, I set it to 93degrees. I then set the differential to 1, for one degree more. Then, at step for, I set it to H1, for heating. Is all of this correct?
