TrueZone Direct Drive

Damper Actuator

APPLICATION

The M847D is a two position, 24 Vac spring return damper

actuator designed to operate directly driven zone dampers,

used to control air flow in ducts. The synchronous motor

actuator can be driven open (or closed) using any 24 volt

rated two position switch - e.g. a wall switch or a thermostat

subbase switch.

The M847D replaces the RDMH and RDMZ damper actuators

for use on ARD, EARD and ZD dampers.
