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.

(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.

TRUEZONE ARD, EARD, AND ZD SERIES DAMPERS WIRING Wiring a Motor See Fig. 6 for motor wiring hookups for ARD and ZD Dampers. 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 M1 and M6 to power the damper closed. The damper then returns to its normal open position once power is removed.
