Review on 🔀 Efficiently Control Zones with the SR501-4 Switching Relay by Jose Moran

I wanted the original (metal case) Taco SR501 single zone changeover relay (part 9300-822). Basically the same as in the picture. But I have a newer (plastic body) SR501-4. I'm sure it worked fine but it has different dimensions so it didn't fit my space and looked different than all my other relays. So returned. I should have paid more attention to the description that says "SR501-4" but I was fooled by the wrong picture. I give 2 stars because the return and refund process was quick and easy. But the picture is still wrong!
