I now have the helix probe taped on second shelf about 1 inch away from the flexwatt... with the helix set at 102 degrees it has the warm side of tub at about 90 degrees... so as long as that holds I guess I am good.

Good to hear.. I hate setting up a new rack.. Took me like 2 weeks of trial and error to get mine.. But now that its set its golden... So fricken pleases with my herpstat.. Un comparable to the dial type zoomed i had before running 6 tubs

I have His previous model with 3 inch belly heat (he use now 4 inch) and herpstat connected..
During summer and with temps around 80-83 degrees in room I had it set on 95 that give me 89 hot spot (top of 1-1.5 inch sani chips substrate) and around 84 cool side... Now temps drop outside so in my room as well...
With 73-75 degree in room now I run it on 102.5-105 degree and that give me 86 hot spot 78-79 cool side... I know that my supper sometimes is late with heating building so from my last winter experience i was running it few days on 115 degree...
Hope that will help...:gj::gj::gj:

P.S You are in FL so if You have Your snake room on constant 77-78 degree... 97-99 on thermostat should do :gj:

Ok i am a little confused. Why are you putting the probe directlly on the heat tape. If im reading this correct you put it on the tape, set the helix at 110 to achieve 91 in the tub? I have vision racks and freedom breeders and every rack has one tub dedicated for the probe so i know exactly what to set it up at. I have the probe sitting over the heat side and my hot side of the tubs stay at 90 and cool side stays at 85.
