Thermostat rant

[Eric Alan]

Ok I am new to owning a herpstat. Actually got it on a deal with four snakes, so it was used when I got it but works great. Eventually I will buy another one when I build a hatchling rack, but that's down the road. If I understand correctly if the herpstat were to fail it will do so in an off position? Also, what if the probe becomes unattached to the heat tape. Will the herpstat one shut off or run a lot of power to the tape?

All Herpstats are programmed to fail in the off position if the sensor goes bad. Most (4 of 6) Herpstats also have a built-in safety relay to cause them to fail in the off position in the event of a mechanical failure.

If the probe becomes detached from the heat tape, it will sense the lower temperature of the open air and increase power to compensate (probably wide open). That would be a user error - do everything you can to ensure this doesn't happen.
