ZD Series Dampers
NOTE: Pages 1-4 are for current ZD damper models. These models have "TZ" at the end of the model number.
Pages 5-8 are for legacy ZD series dampers.
APPLICATION
The ZD is a power close, and spring open damper. It has a
24-volt, spring-return, power-closed damper 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
Honeywell Home TrueZONE zone panels.
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.
Adjustable damper position range stops.
Can be mounted on the side or bottom of the duct, as
the application requires. (Actuator mounted on
second damper dimension listed.)
Quiet operation.
