Thermostat stuff
I know there's been a lot of things posted about our thermostats and how they can quit working. Ours decided to lock up for some reason or another - ambient temp read "00" and nothing worked. After seeing how expensive same - same replacements were, I decided to mess with it for a while. Tried finding the DC fuse for it, but couldn't (had all the 15 amp ones pulled & it still had a display). Pulled the little glass fuse inside it, replaced after a few minutes, and it still was locked up. Finally pulled all power to everything. Turned off the inverter, disconnected the solar panels, disconnected the battery bank and turned the AC breaker in our home off. Turned it all back on the right way and the little pea brain inside the thing woke up and started working again. Have to wait and see if it keeps going, but am beginning to think having little computers inside everything is not always a good thing.
