Works well and looks good
I bought the switching relay to replace the old 20 year old relay, since it did not seem to work anymore. Installing the Taco SR501 was a breeze. I ran new wire (T-Stat, to Boiler, and new power supply) and installed everything in about an hour. Works like it's supposed to!

I have a sr504 relay control. I need to add 1 more zone. Can I use a sr501 and add it to the sr504? Thanks for your answer.

Only -EXP Taco switching relay models are expandable. Regular models, including this one cannot be expanded. Also note that in order to expand an existing -EXP control, your second controls also has to be the -EXP model.
