Used this relay to stage 2 boilers from outdoor reset. Easy to install & set up. Very pleased with the selection, price, and quick delivery

I replaced the electric boiler in my basement due to some heating issues. It only ran off off-peak power (10pm to 6:30am), and it would start running and then shut off after about 45 minutes. The old Taco unit LOOKED okay and had no visible blown fuses or relays, but I replaced it at the advice of the boiler company, and SURE ENOUGH, that was it!

Included bus jumper eliminates one wire, making for a neater wire bundle.
