To correctly connect the touchpad to the Display Board, orient the ribbon connector so
the metallic side of the connector is away from the side of the Logic, as shown in Figure

Diagnostic Operations
There are three diagnostic tests that can be run: The Keypad, the optional airflow
sensor (standard on Type B2 Logics), and the optional canopy airflow sensor.
To access the diagnostic menu, press:
“Menu”
The Display will change to Menu mode. Press the
▲ or ▼ arrows until “Cabinet Set-up”
is selected then press “OK” and then use the ▲ or ▼ arrows to select “Diagnostic Test”
option and then press “OK.”
Keypad Testing
When keypad is selected, the LCD will show when each key is pressed, to
confirm the touch pad is working. In addition, when the Light and UV Light keys
are pressed, the associated relays are energized so the lamps should work. The
timer button energizes an auxiliary relay that closes when the blower is
energized. When “Mute/OK” is pressed, the audio alarm should work. When the
“
▲ ” key is pressed, the Airflow Alarm relay will be energized. When the “ ▼ ”
key is pressed, the Blower On relay will be energized. Finally, the sash position
switches can be checked in this mode as the LCD displays the sash position
information that the controller is receiving.
