Taco Relays Editorial Review

The Taco SR503-4 3 Zone Switching Relay is a useful unit for controlling circulating pumps with room thermostats. It is not designed to replace an aquastat for measuring water temperature nor to work with zone valves. The unit has LED indicators for activated zones but reviews note that they are hard to read. Customers have found the installation process to be easy, especially those who have replaced older, more confusing models. However, there are reports of some faulty circuits in the unit. The manufacturer's warranty covers this, but some customers report difficulty in getting replacements.
