Honeywell TrueZONE ZD12x24TZ 12in x 24in Parallel Blade Zone Damper

ZD12X24TZ - HONEYWELL PARALLEL BLADE ZONE DAMPER 12 X 24 (BOTTOM MOUNT)   The ZD is a power close and spring open damper. It has a 24-volt motor used to control circulating air in heating, cooling and ventilating systems. It is used when a normally-open damper is required. The ZD is typically used with the TrueZONE systems and other electronic zoning systems. Features Kevlar gearing reduces wear, more than doubling damper life. Adjustable range stops. Mechanical visual position indicator for damper status. Solid construction using extruded aluminum frame and blades. Parallel blade design for low leakage performance. Quieter operation with fewer blades. Simple, easy-to-wire, two-wire installation. Reliable, strong, 24-volt spring-return motor. Fail-safe, normally open operation. Compatible with conventional and networked zoning. Ordering Instructions: Order ZD (dimension 1) x (dimension 2). (Motor is always mounted on dimension 2 side.) For example, ZD10x8 is a 10 in. x 8 in. damper with the motor on the 8 in. side; but a ZD8x10 is a 8 in. x 10 in. damper that has the motor on the 10 in. side. Damper can be installed in any orientation (mounting side can be on either the bottom or the side of the duct).
