8.2 Calibration/Service Menu
8.2.1 General
As with the airflow calibration process, the service menu should only be accessed by a Service
Technician that is familiar with the product. Press MENU to access Calibration/Service parameter.
Entry into the Calibration/Service functions requires a service password for entry. After pressing the
Calibration/Service menu item, a password screen will appear. The default password is “9876”.
Once the service password is entered, the Calibration/Service menu will appear.
As a special feature for the service technician, by accessing the Calibration/Service menu, the service technician
can bypass the blower warm up time itself. This feature remains on for one hour from the time the
Calibration/Service menu was accessed. When bypassing the warm up time, it is not uncommon to experience a
brief alarm as the blower stabilizes at setpoint.
