NOTE: The unit must not be operating during the Quick Test function. Set HOA switch to OFF and follow the test pro- cedure. Set HOA switch to AUTO only as required during testing.

To reach a particular test, enter its subfunction number

and then scroll to the desired test by pressing

. A test

can be terminated by pressing

; pressing

after a test

has started terminates the current test and advances the sys- tem to the next test. Once in the next step, you may start

the test by pressing

, advance past it by pressing

, or

back up by pressing

 

. When testing is complete, exit the

Quick Test by pressing

and then

; this MUST

be done to restore the unit software to automatic control. If the keyboard is not used for 10 minutes, the display

returns to the rotating default display.

Press

and

to exit Quick Test and then press
