Step 5: Now, measure the average downflow velocity over the entire workzone using the recommended
downflow velocity test grid (see Table 7.0).
Step 6: Press +/- to change the calibrated downflow value to the average downflow velocity just found.
Press SAVE to enter both the supply duty cycle and the new calibrated downflow value.
Now, the downflow monitor sensor has been calibrated to the actual measured average
downflow velocity. The cabinet will now control to the downflow setpoint.
•
Now, the calibration procedure is complete. If desired, a spot check in the downflow
velocity may be performed if felt necessary.
• Press home icon to exit into run mode.
7.5.3.4 Night Setback Calibration (Optional)
The night set back calibration is performed within the calibration mode after the inflow and downflow
calibration procedure is complete.
NOTE: If night setback exhaust airflow is reduced by the Building Automation System (BAS) and not by
the Nuaire model NU-951-012 valve, this calibration procedure is not necessary. However, it
would still be recommended to use the contacts on the main control board to initiate the night
setback option to display night setback active, inhibit exhaust alarms, light, and internal blower.
Select Night Setback
Step 1: Determine how night setback is initiated. If using contacts on main control board, proceed to
step 2: If using the display icon, enable night setback option by performing the following:
Turn ON night setback option
When the Night Setback option ON the Night Setback icon will appear ON the display to turn night set
