Questions & Answers
Whether you use a 24V power source or transformer, these dampers will need 24V power. Our recommendation is that if you do not know anything about transformers, purchase a wall plug 110/120V primary model A-2 and a 24-volt secondary model A-21. It is easy to find many at a reasonable price. Typically a zone controller or thermostat will supply 24V power to the damper if you are using it to control the dam.
Yes, I agree. Power can be supplied by 24VDC or 24VAC to this damper.
Despite the fact that the damper itself (without the motor) can withstand outdoor exposure, the motor is designed exclusively for indoor use. This damper and motor assembly is suitable for use in a variety of enclosed dry spaces including attics, basements and the underside of homes with pier and beam construction.
Damper motors have the ability to modulate their speed between full open and full closed, but you need to use a controller in order to accomplish this. In order for the damper motor to operate, you need to apply 24 VAC to the open terminals for it to turn open until you stop those Volts, which could be anywhere between fully closed and fully It is the same with the drive close, so you will need a controller that can modulate the voltage to operate it.

The products work very well and withstand a lot of use. These types of dampers use power to open and close, in contrast with common dampers that use power to close and spring to In comparison to Honeywell or equivalent conventional drive mechanics, this one is much more effective. Be sure that your zoning system incorporates an electrical close, and you need three conductors for each damper as opposed to two as required for Honeywell and equivalent systems. As an added bonus, they sell the damper drive as a retrofit, so you can install it yourself. This type of damper will not use as much energy as a normal damper, since they do not use electricity once they are at the end of their movement. A good thing about the stops is that they can easily be adjusted to partially open or close.
I have a 3-zone system powered by an old DuroZone control board. It was easy to swap out the Ecojay dampers with the DuroZone board and the wiring was simple (1,4,6). The three systems have been silent and reliable so far. It's nice to have a warranty that lasts for 5 years. Also, the rubber seal around the blade of the damper is a nice touch, and should help my system operate more efficiently than it did with the old dampers. I give this a five-star rating!.
I liked how tough they are and how easy they are Having those openers open and close electronically as well as the stops being fully adjustable is a plus for me. Another thing I liked was that you could adjust the damper manually after disengaging the clutch, making it easy to calibrate the zones. As soon as I discovered that, all I had to do was connect the power and I was This system is now providing perfect temperature control to all rooms, which was previously a major problem. My personal recommendation for this product is that I highly recommend the company as well. Compared to Honeywell, these were a bit more expensive, but I think the extra cost was well worth the extra money.
I think that these stepper motors work more efficiently than the original spring tension systems. I like how it fits. Installing the product is easy. I like the appearance of the It would have been helpful if wiring instructions were more clear. However, it is a solid.
These plenums are excellent, as are the multi zone control boards. This product works quietly and the staff behind it are fine people who are always willing Be sure you have all the right questions prepared. I strongly recommend this product.
There are no problems with the damper, and I expect it to continue working for a very long time. The design is more reliable than the spring-loaded version. Units need to be returned.
With flex ducts, it is easy to install. There was no trouble with wiring, and setting the hard stops was a breeze. Feels like a high quality professional product The product is of a high quality.
The product works well and is nice to use.
