FILTER CALIBRATION

Filter Calibration
To properly track filter loading, the BFC must be calibrated with the clean filter pressure. Before proceeding, ensure the unit is
operating at the desired airflow. Any changes to the airflow will change the unit pressure and therefore require the filter status to be
reset. For further information on airflow balancing please refer to the FFU Manual. Filter calibration can be performed either directly
through the BFC interface or over BACnet. Each method is described below.
Using the BFC Interface
STEP 1: To calibrate clean filter pressure drop, scroll through the 'Service Menus' until reaching 'Filter'. Select this menu by
pressing the 'Enter/Menu' button (far right).
Note: To enter the Service Menu, hold down the 'Enter/Menu' button for 5 seconds. Display will show 'Passcode'. Use
the Up and Down arrow buttons to enter this sequence:
Down, Up, Up, Down.
STEP 2: Scroll through the 'Filter' menu until reaching 'Reset Filter', select by pressing the 'Enter/Menu'
the area directly beneath and around the unit is clear of any personnel or equipment as this can affect the reading of the
clean filter static pressure.
STEP 3: Press the 'Enter/Menu' button to confirm reset of filter; this will begin calibration. This will take approximately 2 minutes.
After filter calibration is complete, LCD will display:
'RESET COMPLETED'.
