Actuators
Damper Actuators
The damper actuator used with the Unit Vent Controller—0 to 10V Output is a 0 to 10V spring
return electronic damper motor that positions an outside air damper. A 0 to 10V electronic
damper motor can be used to position a face-and-bypass damper.
Valve Actuators
The valve actuators used with the Unit Vent Controller—0 to 10V Output are modulating
spring return and non-spring return electronic valve motors that position the valves.
