setting.
The cooling settings are as shown in Table 1. Compare the settings
on the screen with the options on the unit. Jumpers control all
the settings on the first screen. If there is a discrepancy between
what was ordered and the first screen, compare the wiring on the
controller to the wiring diagram on page 7 or on the unit’s control
