Hydrofarm Thermostat help.

It keeps flashing E3 and not letting me set it up. Anyone else have this issue?

This is what I found on the Hydrofarm website. Hope it helps.

Q: What do the error codes mean on my Heat Mat Thermostat?
A: E1: temperature is below the low limit. Or the temperature sensor has an open circuit. E2: the temperature sensor has a short circuit. E3: temperature is above the high limit. To reset the MTPRTC: Unplug the unit and then while pressing the set button, plug the unit back in.

Thank you; I managed to fix it. Your google-fu is stronger than mine!

Yes, I have strong fu but I don't think we're talking about the same thing.:D

Here's the web page I found that info. The few dealings I've had with Hydrofarm have been very good.
