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.Want to hear YOUR QUESTION on Ask Caleffi?  Take this quick 4 question survey for your chance to hear your question in a future episode.Survey:https://forms.gle/fRfnU8Px3B1Lq7K69Thanks for the sound effects!www.freesfx.co.uk
