SERVICE MODE
SERVICE MODE Menu
The SERVICE MODE key allows the user
to input operating parameters for unit
operation during a service test. Depend-
ing on the particular test being conducted,
the user will cycle through all unit outputs
(i.e.; compressors, fans, dampers,
heaters) and selectively turn them on or
off. After designating the operating status
for each unit component, the user will
designate the “TEST START” delay time.
When a service mode screen displays for

the HI screen will revert to the general
operating status display. If this happens,
