        Comments about Honeywell Switching relay with internal transformer, Dpst line voltage relays:

        Purchased this relay for my boiler to replace an ancient relay that had no provision for a zone control connection to the aquastat. Used the mounting space that the old relay occupied, and wired it up using shielded cable from a local supplier. Easy to read install instructions. Worked on the first try.

        • Primary use:
        • Personal

        Bottom Line Yes, I would recommend this to a friend

              I had the same product as part of my home heating system and it failed. So I wanted to purchase a new one and went to the local distributors and found their price was $50 more than your cost...It was a no brainer. If needed I will use your site and products again. I highly recommend you to anyone.
