Herpstat 1 odd?

[AdamL8]

So when I first got my Herpstat 1 set up and running on the dimming proportional mode it would go around 50% to maintain the temperature I set then 0% if it exceeded it and that was fine for a few days. It would change based on the current temperature of the probe like it's supposed to do. Now I looked at it today and it is only going between 90-100% then to 0% after it hits the number as if it were running on/off. The second it goes under the temperature I set it is immediately at 90-100% instead of trying to match the temperature to the power like it previously did. I checked the settings and nothing has changed. The probe is attached directly to the 4 inch heat tape with aluminum tape. I also did a quick search online and didn't find anything useful. This doesn't seem normal since it didn't start off doing this. Is there something wrong with my Herpstat 1?

Contact Spyder Robotics and ask Dion. He answers questions very quickly.

Probes should not be attached with al. tape.

From your manual...
Do not use aluminum tape on the probe tip. This can cause false readings and poor regulation.

Herpstats will often sit at 0% mine often will run (I have 19) )% 20% 60% 80% then back to zero. The more it sits at zero the more efficient the set up is. The more time it sits at high % the less efficient it is.

Dion is fab his service is better than anyone else.

What do you use to hold your probes on? Aluminum tape was just what I had seen other people use before and made sense as I would think that it would take in more of the heat from the heat tape and not from the air temp.

I will use aluminum tape on the wire directly behind the probe when mounting it to a uth. The weight of the cages then keep the probe in contact with the uth.

It conducts and traps heat when over the probe. Thus your Tstat will read higher and regulate the enclosure at a lower rate.

I've always used regular scotch on the probe cord. Just tape the cord closest to the probe. You can even tape down the very tip of the probe as well. Just don't cover it.

I wish I had taken a picture of mine to show you. I secured my probe by taping down the wire and folding a piece of paper a couple times over and putting the paper over the probe and taping down the sides of the paper. That way it holds the probe tightly to the heat tape and allows ventilation around it so as not to give false readings or trap heat and cut off heat before reaching the right temp.

So the only thing that I had found when I searched this issue online had somebody say to do a master reset on the Herpstat but that didn't solve the problem for that person. I did it anyways and at least for the time being it is working correctly going between 40% and 0% when it hits the temperature. I haven't changed the tape yet but I will do that regardless of whether the problem comes back or not. I'll be keeping a close eye on this though because now I'm curious as to why it only got to that point over time but a quick reset was able to fix it instantly even though I changed all the settings back right after the reset.

[AdamL8]

It's right back to doing it so I'll change the tape right now and see what happens with it.

Edit: I'll change the tape after the BP on that row finishes eating because she is not a good eater.

Changing the tape out so that the probe is just pinned down but with the middle section completely open seems to have fixed it for the past few hours. I'm sure that must have been the problem and it will be just fine now. Thanks for all the help.
