Moist-N-Aire temperature gauge question

[irratebass]

Thanks guys, I had it at 50 and was good at 64,65 & 67 (3 hygrometers top, middle and bottom) I turned it up to 60 and it was at 71, 74 & 77!!! so I put it back down to 50, will check tonight when I get off work.

I just wasn't sure if there was a scale out there that I needed to go by, I am thinking 50-55 is the ticket.
