Honeywell YTH8321R1002

Outstanding Performance:
This damper was specifically designed with R8 insulation specification in mind to contribute to energy savings and help the system pass efficiency audits. Best of all, it helps eliminate hot and cold spots, the biggest cause of callbacks. The improved internal design creates a slower return that ensures a quiet operation.
Installation Made Easy
For fast, accurate installation with no callbacks, the TrueZONE Damper has you covered with a range of features that simplify installation in most applications:

Adjustable Range Stops  Easy to understand and set by utilizing a pushin lever. Theyre used to bleed air into the zones which helps lower pressure and reduce noise.

Push-In Terminals  The same easy wiring design used on TrueZONE Panels. No tools needed, has space for two wires.

Taping Flange  Lets you position insulation under it before sealing with foil tape.

Mechanical Position Indicator  Easy viewing through a clear window.

LED Indicator Lights  Red indicates the damper is closed and green indicates open (used in 3-wire applications)
