It seems that hydronic zone valves have been around forever. They are pretty bulletproof! But do you hear about end switches failing? What's going on? AND... what do I need to know before wiring a zone valve?
In this Episode, Greg and Dan discuss this common question from our Technical Support line: What's wrong with my actuator? Our Tech Support Gurus find that the culprit is typically a misapplication of the "end switch", a.k.a. the micro-switch. They explain the role of an actuator that contains a micro-switch and what kind of inrush thresholds are required to operate them successfully. They also talk about optimal installations including utilizing actuators with a ZVR relay control board that provides your customer with a top-notch product AND a top-notch warranty.
Thanks for tuning in!
