Essential Info

As energy costs rise, it is important to find different solutions that help conserve energy and keep your heating and cooling expenses to a minimum. Because heaters and air conditioners are the largest energy consumers in homes today, one way to start reducing the use of energy is to install electronic air duct dampers. The Suncourt Zonemaster is a 6-Inch Diameter Normally Closed Electronic HVAC Air Duct Damper with Power Supply that allows you to shut off airflow to unoccupied or unused rooms, which limits the flow of heated or cooled air to the areas that really need it. The airflow changes the temperature in the occupied areas faster than conventional air ducts, providing shorter run times for your heating and/or cooling system, allowing you to use less energy and save money. By adding one or more dampers you can create zones throughout your home that can be electronically controlled. A 24 Volt hardwired power supply is included that can be used to connect with an HVAC zone controller and a multi-zone thermostat.


What's Included

  • 1x - 6-Inch Diameter Normally Closed Electronic HVAC Air Duct Damper
  • 1x - 24 Volt Power Supply Transformer
  • More Info

    Multi-Zone Control
    Enjoy having complete electronic control of which rooms your HVAC system heats or cools by using dampers in conjunction with one of the following RCS HVAC air duct zone controllers and a multi-zone thermostat:
  • 2-Zone Controller
  • 4-Zone Controller

    Single Zone Control with INSTEON
    This electronic damper also offers the flexibility of being controlled from your INSTEON network by connecting a plug-in 24V AC power supply to the damper and plugging it into an ApplianceLinc. Once that connection has been made the damper can then be operated from any INSTEON controller, such as a KeypadLinc, SwitchLinc or RemoteLinc; all items sold separately.

    For wiring between the damper and zone controller, damper and power supply, or zone controller and power supply, simply run 2-conductor wire between them. 18-gauge or 22-gauge wire is recommended.

    Normally-Open or Normally-Closed Models
    When no power is supplied to the Normally Closed unit, the damper will be closed. When no power is supplied to the Normally Open unit, the damper will be open.

    8 inch diameter

    Excellent product. Excellent price. Fast reliable shipping.
    STANLEY -- rochester, NY   6/30/2014
    Damper opens and closes properly, albeit with a small (unimportant) air leak when completely closed. The motor runs very warm; therefore provide adequate cooling. The label indicates a 0.25A @ 24VAC. However, I measured around 0.44A. Again, keep it cool.

    Just what I need for an air diversion project
    JUSTIN -- spokane vly, WA   5/16/2014
    Works like a champ and a Great price.
    PAUL -- centreville, NS   4/24/2014
    The product was exactly what I needed. It operates very well and was easy to install following the installation and wiring instructions. Shipping was very fast and arrived undamaged. Thank you for everything.
    Dave -- Calgary   4/22/2014
    The one thing this does not solve is how to zone your home when you have a finished drywalled ceiling in your basement. Same for 2 story houses. You do not have easy access to ducts are faced with cutting holes in ceilings, running wires which usually means more holes and then matching the ceiling texture, paint, stipple or whatever once the holes are filled. I'm waiting for a creative idea.
    KENNETH A -- greeley, CO   3/27/2014
    Works well and just pushes into ductwork to install. It's being used as a fresh air intake control. Well made device.
    GORDON -- cincinnati, OH   2/8/2014
    Exactly what I was looking for. Use it to open combustion air duct when furnace is running. Tied transformer primary into combustion induction fan which comes on prior to gas ignition.
    MARK -- oakdale, CT   12/9/2013
    Exactly what I needed. Fast shipping. Free shipping. Excellent product. Excellent service.
    PAUL F -- silver spring, MD   11/30/2013
    A economical way to install a make up air or fresh air intake. Compared with other brands. Works great
    MATTHEW -- woods cross, UT   9/14/2013
    Worked just as it should, packing was great, no damage.
    STEPHEN -- marion, MA   1/26/2013
    Works excellent. very satisfied.Simple installation. Used it to bring in outside air to my furnace room. Opens when boiler comes on and closes when it shuts down.
    JACOB -- kingston, ON   4/19/2012
    As advertised. Readily installed if you have basic metal cutting and wiring skills (and tools). Instructions were clear.
    DOUG -- regina, SK   2/26/2012

    RONALD -- union, KY   2/13/2012
    This is the second damper I purchased.Works great and I am well satisfied. The price was right and I received the shipment much sooner than I expected. Many thanls
    CHUCK -- portland, OR   1/4/2012
    Worked as advertised.
    Chuck -- Oreogn   12/15/2011
    Suncort makes good stuff. I got one of these for my home automation zone system. Put it in and connected it to a Insteon appliance module. When the temperature of the guest room drops below a certain point it opens when the furnace is on and heats that room. Once the furnace goes off the damper closes. Totally seamless.
    DAVID -- chuckey, TN   11/23/2011
    I used this to open the bypass duct automatically whenever my whole house bypass humidifier kicks in. Saves me a lot of energy and fully automates the system. Very good seal when closed. Lets virtually no air through.
