TrueZONE ARD, EARD, and ZD

Series Dampers

APPLICATION

ARD Series Damper

The ARD is a round damper with a 24 Vac, spring-Open return

damper motor used to control circulating air in heating,

cooling, and ventilating systems.

EARD Series Damper

The EARD is a round damper with a 24 Vac powered-open/

spring-closed motor. It is used for fresh air intake for

Ventilation or for combustion makeup air.

ZD Series Damper

The ZD is a power close and spring open damper. It has a 24-

volt motor used to control circulating air in HVAC systems and

used when a normally-open damper is required. The ZD is

typically used with the TrueZONE and other electronic zoning

systems.

FEATURES

• Taping Flange and non-interfering set screw

• High Temperature outer plastic for hot environments

• Redesigned all Metal Drive Train Gears

• Front facing display with LED Indication light for Open

and Close.

ARD Features

• Adjustable close position range stops

• Shipped as power closed/spring return open damper.

• Available in 5 to 10” inch, 12, 14, 16, 18, and 20 inch

diameter sizes.

• Male (crimped) and female (uncrimped) ends to connect to

any rigid or flexible round duct.

• Rated to operate up to 1 in. wc

• Blade closes off tightly against gasket for minimal leakage.

• Fail-safe, normally open operation

• Simple, easy-to-wire, two-wire installation with a third wire

option M4 for LED open only light

EARD Features

• Adjustable open position range stops

• Shipped as power open/spring return closed damper.

• Blade closes off tightly against gasket for minimal leakage.

• Galvanized steel

• Rated to operate up to 1 in. wc

• Simple, easy-to-wire, two-wire installation

• Male (crimped) and female (uncrimped) ends to connect to

any rigid or flexible round duct.

ZD Features

• Adjustable closed position range stops

• Rated to operate up to 1 in. wc

• Solid construction using extruded aluminum frame and

blades

• Parallel blade design for low leakage performance

• Simple, easy-to-wire, two-wire installation with a third wire

option M4 for LED open light

• Fail-safe, normally open operation

• Ordering Instructions: Order ZD (dimension 1) x

(dimension 2). (Motor is always mounted on dimension 2

side.) For example, ZD10x8TZ is a 10 in. x 8 in. damper

with the motor on the 8 in. side; but a ZD8x10TZ 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).

TRUEZONE ARD, EARD, AND ZD SERIES DAMPERS Installing the Round (ARD and EARD) Dampers 1. 2. 3. Planning the Installation Selecting a Location Insert the crimped end of the ARD or EARD into the uncrimped end of the rigid round duct and secure with sheet metal screws (not provided). When using flexible duct, slip the duct over the end of the ARD or EARD and secure it with duct straps (not provided).

TRUEZONE ARD, EARD, AND ZD SERIES DAMPERS WIRING Wiring a Single ARD (Power Closed) to a Control Panel CAUTION Personal Electrical Shock Hazard. Can cause electrical shock or equipment damage. Disconnect power before beginning installation. The damper motor has a 24 Vac, 50/60 cycle, 8 VA rating. The spring-return ARD and ZD damper requires 24 Vac to the two motor leads to power the damper closed. The damper then returns to its normal open position once power is removed.

TRUEZONE ARD, EARD, AND ZD SERIES DAMPERS CHECKOUT To check out the EARD: 1. With 24 Vac applied to the motor leads, observe the motor powering the damper to the open position. 2. When energized, verify that the actuator connection coupling rotates in a clockwise direction (as viewed from the operator base end) and that the damper shaft turns with the coupling. 3. With power removed, observe the damper returning to the normally-closed position.
