The upper limit of the fan speed in AUTO is the speed decided by indoor fan speed control. When the temperature of RT has been 37 C or more, or when the set speed has been changed, this control is released and the fan speed is the set speed. (4) Flow soft control When the thermostat (compressor) is off, the indoor fan operates as follows. Compressor OFF ON Fan VLo Set speed NOTE : When the thermostat(compressor) turns on, the fan will operate at set speed. But until cold air prevention and warm air control is released, the fan speed follow them.. High pressure protection In HEAT mode and manually-operated HEAT mode, the indoor coil thermistor detects the temperature at the indoor heat exchanger and controls the compressor rotational frequency to prevent the condensing pressure from increasing excessively. 3. Overload starting When the room temperature thermistor reads 8 C or above, the compressor runs with its maximum frequency regulated for 3 minutes after the start-up. 4. Defrosting () Starting conditions of defrosting a) The defrost thermistor attached to the outdoor heat exchanger read -3 C or below. b) The cumulative operation time of the compressor has reached any of the set values: 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 00, 05 minutes. c) More than 5 minutes have passed since the start-up of the compressor. When the above three conditions, a), b), and c), are satisfied, the defrosting starts. w Set value of compressor operation time(hereinafter referred to as defrost interval) The first defrost interval is 3 minutes long, and the second 35 minutes long.the third and subsequent intervals are set to be longer, and less frequent, depending on defrosting time. The third and subsequent defrost intervals follow any of the three patterns 5 or 0 minutes longer, the same, or 5 or 0 minutes shorter compared with the previous defrost interval with the longest 5 minutes and the shortest 30 minutes. () Releasing conditions of defrosting Defrosting is released when any of the following condition is satisfied: a) The defrost thermistor reads 3 C or above. b) Defrosting time has exceeded 0 minutes. c) Some other mode than HEAT mode is set during defrosting. 7

(4) Indoor fan speed control, high pressure protection, defrosting, 4-way valve control are the same as HEAT mode of I FEEL CONTROL 8-5. FAN MOTOR CONTROL. 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 (Hi,Me,Lo) the microprocessor controls SR4 and adjusts fan motor electric current 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.. Fan motor lock-up protection When the rotational frequency feedback signal is not output for seconds, (or when the microprocessor cannot detect the signal for seconds) the fan motor is regarded locked-up. Then the electric current to the fan motor is shut off. 3 minutes later, the electric current is applied to the fan motor again. During the fan motor lock-up, the OPERATION INDI- CATOR lamp flashes on and off to show the fan motor abnormality. (See page 4.) 8-6. AUTO VANE OPERATION () Vane motor drive These models are equipped with a stepping motor for the horizontal vane. The rotating direction, speed, and angle of the motor are controlled by pulse signals (approx. V) transmitted from indoor microprocessor. VANE () The horizontal vane angle and mode changes as follows by pressing the VANE CONTROL ( ) button. (3) Positioning The vane is once pressed to the vane stopper below to confirm the standard position and then set to the desired angle. Confirming of standard position is performed in case of follows. (a) When the OPERATE/STOP(ON/OFF) button is pressed. (b) When the vane control is changed AUTO to MANUAL. (c) When the SWING is finished. (d) When the test run starts. (e) When the power supply turns ON. (4) VANE AUTO ( ) mode In VANE AUTO mode, the microprocessor automatically determines the vane angle and operation to make the optimum room-temperature distribution. () In COOL and DRY operation Vane angle is fixed to Angle. () In HEAT operation Vane angle is fixed to Angle 4. 9
