CONFIGURATION DIP SWITCHES S1-1 & S1-2
Open-Loop -- Fan filter unit is controlled by a controller, i.e. on-board potentiometer or
network controller.
Closed-Loop -- A sensor is used to maintain airflow, i.e. room pressure, roomtemp, or a
particle counter.
Analog Setpoint -- Unit is controlled with an analog contoller, i.e. on-board potentiometer or individual wall mounted
controller (must be determined before ordering)
Network Setpoint -- Unit is controlled with a networked controller, i.e. ACC1 or ACM7052 touchscreen controller
*Leave shunt out if using
a 0-20mA or 4-20mA sensor.
