“I replaced 3 Honeywell relays with this product. The wiring for this Taco is much simpler and it does have one relay with priority. Very happy with this purchase.”
“Easy to install. really delivered, quick shipping and they even included resistors for "power sharing" thermostats (Nest, Ecobee, etc)! Would definitely buy again!”
“This single-zone relay is exactly what was needed to install a WiFi thermostat to my hydronic radiant floor. Previously the radiant floor ran off a timer, but now this interface with WiFi lets me see and control the temperature of my basement from my cellphone, wherever I go. Yup that's what it did and it destroyed my indirect hot water tank. I just had to replace my indirect hot water tank because the priority DHW zone would not cut off once the priority was satisfied. I was wondering wtf would cause the top of the indirect water tank to rupture but initially chalked it up to a nearly 15 year old water tank. Nope - once the new tank was installed and everything else was checked out/maintained/replaced we had the same exact problem the priority DHW zone circulator pump stayed on rather than cut off when the priority was satisfied (all that pressure that had the old Tank's relief valve singing now makes sense too). That's when we realized that this unit actually caused the issue”
“After 37 years in the heating profession, wiring relay after relay after relay is finished!! You run one power line in, loop to each circulator, hook up thermostats and boiler TT all in one place!”
