“Same part number, but completely different physical size/layout. It works, but I had to re-route wires. I do mostly repairs, so it's a bit of a pain. They should use a different part number. But can't complain it's a mfg issue.”
“This worked great for my application. I have a 1 zone in-floor radiant heat system from the 60's. All I needed to control is a 12vac gas valve for the boiler and the 120vac circulation pump. The Taco relay did the job.”
“Added another zone for heat and rather than buying the single zone controller and adding it to the existing controller for a few dollars more, I just replaced the entire unit-works well, just as expected.”
