than the accurite can't monitor the cold side temperature? i like to have both as for some reason the fuse in my house central heating keep on going out. the cold side is usually 2-3 degrees above room temp but not always. i do check with temp gun but I'm quite busy sometimes i pop into my room for under 10 second before i'm on my way again i want to do a visual scan to make sure everything is alright.

T stat probe is tape properly and the t stat i have secure to the top of the rack so thats not a problem.

Do everybody with rack just temp gun check?
