Description
The ZD is a power close and spring open damper
It has a 24 V motor used to control circulating air in HV systems and used when a normally open damper is required
The ZD is typically used with the TrueZONE® and other electronic zoning systems
Mechanical visual position indicator for damper status
Solid construction using extruded aluminum frame and blades
Parallel blade design for low leakage performance
Simple, easy to wire, two-wire installation
Reliable, strong, 24 V spring return motor
Fail safe, normally open operation
Damper can be installed in any orientation
Taping flange and non-interfering setscrew
High temperature outer plastic for hot environments
Redesigned all metal drive train gears
Front facing display with LED indication light for open and close
Adjustable damper position range stops
90 deg motor nominal angular rotation
Less than 1% at 1/2 in-WC leakage
Clockwise, when energized and viewed from the base or shaft end motor shaft rotation direction
Direct connection to damper shaft
Terminals M1-power, M6 common, M4 (optional) LED indication wires to motor
