CONTROLS

The fan filter unit can be controlled through various inputs:

1.  Local potentiometer control

-  Adjust airflow from the face

-  Adjust flow from back of unit (disabled if face control present)

2.  Individual unit wall mounted control (must be determined before ordering)

3.  0 - 10V/0 - 5V DC Control

4.  0 - 20mA/4 - 20mA Control

5.  Full range of network controls including connection to BAS/BMS through MODBUS RTU RS485 control

- BACNet IP, BACNet MS/TP, & LONWorks available with additional hardware

Additionally, monitoring and control of the FFU can be done through closed loop control from

sensors such as pressure transducers, thermostats, partical counters, etc.

This manual will give basic information on how to connect controls and sensors to the unit.  For

more details refer to the instructions included with the controller or sensors.

WALL MOUNT POTENTIOMETER CONTROL

Potentiometer and wall plate are provided with this option. It is factory hard wired and tested.

Signal is 0-10VDC. Potentiometer is 0-10K Ohms.

To relocate the potentiometer cut the wires leaving enough lead to make new connections. Run 3 conductor wire rated for the 

requirements of the installation and meeting all relevant codes. If possible use strain relief at the fan filter unit.

Connect wires like to like at each end of the extension leads. Retest unit to verify operation.
