Night Setback Calibration (see calibration section)
The night set back calibration is performed within the calibration mode after the inflow and downflow
calibration procedure is complete.
Exhaust Damper Set up
Exhaust Airflow Control
This parameter allows for the selection of time, programmable from 30 to 240 seconds
determining how often the exhaust controller updates the control signal to the automatic damper (i.e. NU-951-
012) if installed. Reducing the time will cause the damper to react quicker to change but may result in control
Overshoot and oscillations. Increasing the time will cause the damper to react slower to changes but may not keep
up with normal systems fluctuations. Depending upon the HVAC system, changing this parameter allows control
flexibility for exhaust system optimization.
