Testing, Wiring, Taco Sentry Zone Valve! How it Works, Comparison, Explained!

This HVAC Training Video goes over the High-Efficiency Taco Sentry Zone Valve. I go over installation practices, head removal, wiring, amp draw, connection to a zone control relay system, operation, and comparison with the older taco 3 wire 571 zone valve. Proper knowledge of applications and operations leads to better troubleshooting procedures.
