So I bought a Herpstat 2 Redline. Set it up yesterday and it was running fine - temps were steady where I set them when I went to bed. It ran for probably 8 hours before I went to bed. I checked it once sometime over night, still good.

I had a Zoomed UTH set up on one output, an infrared bulb set up on another output. Both were set on dimming.

I got up this morning with the display reading “Error detected - 120v A.C. signal”.

I can’t find anything anywhere that tells me what this means. Anyone know?
