Customer Question
I have a taco...

I have a taco zone sentry on my fan coil unit. when I turn on the power to the unit and the fan comes on the green lights do not blink indicating it is on. I took one of the taco zone sentrys office of the fan coil unit I am talking about and put it on another fan coil unit...it worked on that unit...the green light flashed and the valve turned. Any suggestions?

Contractor's Assistant: Did you double-check the thermostat? And what about the unit's filters?

The thermostat is working. How would the filter affect it?

Contractor's Assistant: Do you plan on doing the work yourself?

Yes

Contractor's Assistant: Anything else we should know to help you best?

Can't think of anything else

Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation.

If the unit works when you swap the head for one that you know works then you need to replace the head on the problem unit.

Not wat I thought you were saying. Sounds like the zone valve isn't getting a call to open from the fan coil. Need a brand and model of fan coil to advise you further re: troubleshooting why.

Can't find specs on this unit. Maybe one of my colleagues can help. Please don't respond (even to acknowledge this post)until you get a response from us. If you respond first it will only delay your answer.
