If the DIP switches are set when the power is still ON, the new set-
ting will not be enabled immediately. The change only is enabled
when the power is cycled, or if the Reset button is pressed.
•
When executing the test operation, check the operating condition
of the indoor unit and only execute the test when all indoor units
have stopped operation.
•
Auto test operation will not work where only one indoor unit is
connected to the Space II unit.
•
Heat Pump model functions do not work on Cooling Only models.
