Application:
The NSPRD-12  Normally open or Normally closed  Damper is perfect for direct control from a thermostat or switch, since a one wire call on a thermostat’s Y or W outputs will cause the damper to open.
(If you would prefer a non spring return damper that will still operate with just one wire control from a thermostat, check out our SD super duty dampers at our store “DamperDirect” ).
On Zone control systems, you may set this damper to spring open, and power to close. This two wire damper is compatible with any 24vac zone control system.
DamperDirect  offers all types of dampers and old fashioned service.  If you have any technical questions, please message us via Ebay.
other notes:
Multiple dampers will be combined in one box as practical.
Order either our 24vac plug in or hard wired transformer for power, and any of our Robertshaw RS series thermostats will control this damper.  Looking for 3 wire and commercial grade dampers? See our store DamperDirect.
