Hi, I live in a condo with water based heating and AC. I woke up to a loud ticking or panning noise coming from the AC unit. Unfortunately there is no model number on this unit as the painter sprayed over the tag. I believe its called a Climetec fan coil unit.
I removed the cover and the noise is coming from a Honeywell VC4011-12 valve actuator which is continuously cycling on and off. I can turn off the AC at the thermostat, or close the manual water valve but no relief.. it just keeps hammering away. It stops when I turn power off to the whole AC unit.
Is the valve defective? Or could this be a symptom of some other problem?
Thanks
Bob
