SERVICE MODE Menu (Local Human Interface only)
The SERVICE MODE menu is used to input operating parameters for unit operation
during a service test. Depending on the particular test being conducted, the user will
cycle through all unit outputs (compressors, fans, dampers, heaters, etc.) and
selectively turn them On or Off for the test. After designating the operating status for
each unit component, the operator will designate the “TEST START” delay time.
When a service mode screen is displayed for 30 minutes without a key being pressed,
the LCD screen will revert to the general operating status display. If this happens, press
the SERVICE MODE key again to return to the service menu.
Note: Many of the screens displayed in this section are applicable only for the options
that are installed in the unit and may not be visible on your unit.
To operate the system in the TEST MODE, press the SERVICE MODE key to enter into
the service mode menu and scroll through all of the system outputs and selectively turn
them “On” or “Off”.
