8.“SLEEP” mode
When the SLEEP button is pressed, the SLEEP mode is selected as following:
The indoor fan speed is set at the low speed, the power lamp and the sleep lamp is on, the temperature off after 5 minutes.
When selecting COOLING/DRY operation with SLEEP mode, the set temperature will be raised by 1.8℉ 1 hour later and by 3.6℉ 2 hour later.
When selecting HEATING operation with SLEEP mode, the set temperature will be dropped by 1.8℉ 1 hour later and 3.6℉ 2 hour later.
After the System operates in SLEEP mode for 8 hours, it will stop automatically.
9.Fan motor control
(1)Rotational frequency feedback control
The indoor fan motor is equipped with a rotational frequency sensor, and outputs signal to the microprocessor to feedback the rotational frequency. Comparing the current rotational frequency with the target rotational frequency, the microprocessor adjusts fan motor electric to make the current rotational frequency close to the target rotational frequency. With this control, when the fan speed is switched, the rotational frequency changes smoothly.
(2)When the rotational frequency feedback signal has not output for 5 seconds (or when the microprocessor can’t detect the signal for 5 seconds), the fan motor is regarded
