Problems with VE-300 historical low temps...

[cchardwick]

I bought a brand new VE-300 straight from Reptile Basics and when I got it the historical low temps were all over the place even though I had it set to 88F with a night drop of zero degrees. At one point it said the low temp was 45F! I put another temp probe at the same location on the heat strip that measured high and low temps and it said that the temps were not varying more than plus / minus two degrees. I complained about it and Reptile Basics sent me a different VE-300. But now my new VE-300 is doing the same thing, last night it showed a low temp of 75F but my other probe said the low was 86F. Anyone else have this problem?

My VE-300 or any VE thermostats have never had that problem.

Where is your thermostat probe?

Is it possible it is showing the low from when you first turned it on?

Do you have the high/low alarms set? If you do and it doesn't go off then there's no way it is getting that low unless you have it set lower than what it is getting to.

Also, is it possible the probe has come loose?

Actually I didn't think about the alarms, that should have went off! I do have the alarms turned on and the probe is taped to the ARS rack heat strip. I have another probe taped right next to it, the low temps are incorrect. I'm thinking it may be a bad probe? Reptile Basics thought it was a bad battery and sent me the replacement unit, hard to believe the same thing is wrong in both units.

I would test your alarms by taking off the probe and letting it drop temp to see if it goes off. Only other thing I could think is maybe there was something that caused a momentary temp drop but went back up immediately, seems unlikely but you never know since the probes are very sensitive. Maybe after testing alarm unplug probe, plug back in, clear history, and see if it shows another temp drop tomorrow morning.
