4.1 Diagnostics Mode
Enter the diagnostics mode by pressing and holding the “Warmer” keypad while pressing the “Colder”
keypad four (4) times within five (5) seconds. The display will flash both the software and firmware ver-
sion.
At this time depress the “Set” keypad once more. This will enter the Service Mode where individual
components can be tested individually.
Continue to press the “Set” keypad one time to access the test mode for each specific component. The
status of each component can then be tested by pressing either the “Warmer” or “Colder” button to cycle
each component. The “Warmer” keypad will turn each component on and the “Colder” keypad will turn
them off.
When testing the status of each thermistor the display will only show the status of the current condition.
When testing the status of the door reed switch a magnet held between the “On/Off” keypad and display
will show the status. The “Warmer” / “Colder” keypad serve no purpose for this test.
The Service Mode will time out and return to the main display mode after five (5) minutes if keypad is
left idle.
