Description
The ClimateMaster 23B0012N11 Normally Closed Actuator with End Switch is an electrically operated damper that is used to position HVAC systems in geothermal, air handling, and ventilation. It maintains the damper in the closed position when de-energized and closes in response to a 24-volt control signal and has built-in end switches to give feedback to the control system. This is installed on round or rectangular dampers in ductwork or loop controls in a heat pump system and it assists in coordinated system response and adequate control of airflow in compatible systems.
