UVC Unit Modes
The UVC provides several “normal” modes of unit operation. These include: Off, Night Purge, Fan Only, Cool, Emergency Heat, Auto, Heat, and Cool.
Normal UVC modes can contain a single state or several states depending upon the functionality required for each particular mode. Each UVC state is assigned a number, which can be very helpful when trying to understand which state is currently active within the UVC. To view the current UVC state number, use the keypad/display.
