“Needed to control a Taco circulating pump for a small radiant floor system. I have 1 zone for heating the North-facing roof for snow removal, and the other zone for heating the Master bathroom floor. I needed to control only the floor heat and this single zone relay works great.”
“I was using this unit as a way to tidy up some wiring while providing a 24 Vac source for a controller. If zone 1 is not being used, you MUST remove the jumper powering the zone1 area of the board or the unit will not provide reliable 24 Vac upon power loss & recovery.”
“The Taco SR501 has and is a very reliable product. I have utilized this product on hydronic systems for fan coils and single zone use for the past 15 years. No issues have been encountered to date with this product.”
“Taco switching relays are easy to use and install. Very versatile and expandable. I am using one for the main heating loops and DHW, and a second to control a glycol-based, slab radiant system. Up and running with ease.”
“I like this switching relay instead of the ARGO or Honeywell models because of the LED indicators. Customers like to see visual status of system operation.”
