Another Control Thermostat bites the dust

[Topperace]

On my 4th Aqua Hot Control Thermostat in less than two years… see other threads I’ve posted on the Forum regarding Aqua Hot 250P issues.
This time however, the control board indicator lights were not all lit as before, so
I went down a few rabbit holes to correct the problem. I will not tell about the bonehead troubleshooting gaff I did that took me down the wrong rabbit hole, but needless to say, it ended up being a bad Control Thermostat… AGAIN!!

So this time, I decided to go ahead a replace the overflow tank that I had for spare as the old one had gunk in the bottom. I also, flushed the tank as the fluid was getting dark. Will clean up the dirt and grime in the bay, and the Aqua Hot
system…got a little dirty.

I will be on with Aqua Hot Customer Support tomorrow, getting another Control Thermostat for back up…the last one only lasted three months.
