this control does not work in the indoor unit.
(9) ECONO COOL (
) operation (ECONOmical operation)
When ECONO COOL button is pressed in COOL mode, set temperature is automatically set 4°F (2°C) higher by the
microprocessor. However, the temperature on the LCD screen on the remote controller is not changed. Also the hori-
