I recently had trouble with one of my Honeywell zone valves which I mistakenly diagnosed as a problem with an Argo AR861 Zone Relay. Long story short I replaced it with a Argo ARM-4P (I have 4 zone valves and 2 circulating pumps, main and DHW Super Stor indirect water heater). In the process of replacing it I realized that perhaps a less convoluted wiring/switching method would better serve diagnosing future problems.
I have though about replacing the ARM-4P with the Taco ZVC 404. Is it worth it? Is the switching relay a more reliable piece of equipment. Shouldn't the original set-up used a zone valve control instead of a jury-rigged switching relay?
