Hello, you probably have them wired incorrectly.... tell me how many wires are attached to each damper please, and the model number of the damper.
The 2 wire dampers are spring open, and 24voltAC to close... it is also possible to adjust the damper blades on the damper motor shaft incorrectly, tell me if you done any of those adjustments or if you used the damper as it came (best way)
We can go from there.
Thanks, ***** ***** the model number of each damper then I will pull the manual on it and mark it up showing you the correct wiring.
Phone calls are $25 extra, lets just stay in this dialog box for now,
That is an example of various models of dampers and the blade adjustments etc that can be made.
this is why I need each dampers model number
Yes it is, I am looking it up now
See wiring on page 4
Let me know how that works, we can go from there if needed.
When you have what you need, please locate the 'finish and rate' link and click on it, that is the only way the company pays me for my time.
Thanks, next read the instructions in that damper manual on how to set the blade adjustments. page 3
The dampers need to be set for *spring closed... right now they are set for 'spring open'... and that is the problem.
Sometimes you have to rotate the damper disc on the damper motor shaft 90 degrees to reverse the 'spring open' so that it is 'spring closed'... that can be tricky but working with it for a bit solves that
