“Makes adding a wi-fi therm to your customers' homes easy and straightforward. Allows use of the lower-priced therms that require a "C" terminal. After all, not all can afford a Nest.”
“I have been using these relays for a while and they never disappointed me. Very good reliable relays. I highly recommend the Taco SR501 to anyone in need of a new relay for their heating system.”
“This was a perfect replacement for our old 1970's Burnham boiler that had a Flair Mfg relay. One of the original ones had failed. With a little change of the wiring, we were back in service in no time. Also, can't beat the price that was $30 less than the local distributor!!! Received quickly. Very satisfied!”
“This is a redesigned SR501 relay. There are no small fuses. Overall it appears to be higher quality. I hope that it proves to be more reliable than TACO's older version. The older ones were problematic on the low voltage side. (They seemed to overheat).”
