CONTROL SYSTEM 11. CONTROL SYSTEM 11.1 SAFETY CONTROL 11.1.1 Time delay safety control a. 3 minutes delay for compressor—the compressor is ceased for 3 minutes to balance the pressure in the refrigenration cycle in order to protect the compressor. b. 2 minutes delay for 4-way valve—The 4-way valve is ceased for 2 minutes to prevent the refrigenrant-gas abnormal noise when the HEATING operation is OFF or switch to the other operation mode. 11.1.
PAGE 37
CONTROL SYSTEM 11.4 “DRY” Mode Operation 1.4.1 The system for DRY operation used the same refrigerant circle as the cooling circle. 12.4.2 When the system operates in DRY mode, at first it operates in cooling mode at 16OC or 18OC for 3 minutes. And then, the system operates in cooling mode with low speed that regards the temperature of the room temperature sensor reads decrease 2OC as the set temperature.

CONTROL SYSTEM 11.5.5 Defrost Defrosting of the outdoor heat exchange is controlled by the microprocessor with detection by the indoor pipe temperature sensor. Defrost control type is according to the JC on the PCB whether is connected. 1. When the JC is connect on the PCB When one of the conditions of A, Band C is satisfy, the defrosting operation stars. In the condition A, it must satisfy the condition a),b) and c) then into defrosting operation.
PAGE 39
CONTROL SYSTEM B. After the compressor cumulative operation time exceeds 120 minutes and the temperature of the IPT is less then 35OC for 2 minutes. When the defrosting operation time on this condition exceeds 8minutes, it will terminate. C. After the compressor operation continuously for 20 minutes and the IPT is less than 23OC or from the last time of defrosting operation is 50 minutes or more intervals. When the defrosting operation time on this condition exceeds 10 minutes, it will terminal. 2.

CONTROL SYSTEM 11.8 “SLEEP” mode When the SLEEP button is pressed, the SLEEP mode is selected as following: 1. 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. 2. When selecting COOLING/DRY operation with SLEEP mode, the set temperature will be raised by 1OC 1 hour later and 2OC 2 hour later. 3. When selecting HEATING operation with SLEEP mode, the set temperature will be dropped by 1OC 1 hour later and 2OC 2 hour later. 4.

CONTROL SYSTEM 11.11.2 Positioning The vane is once pressed to the cane stopper below to confirm the standard position and then set to the desired angle. The positioning is decided as follows: a. When the ON/OFF button is pressed. b. When the vane control is change from AUTO to MANUAL. c. When the SWING is finished. d. When the test run starts. e. When the power supply turns ON. 11.11.3 The auto vane changes as follows by pressing the VANE CONTROL button. 11.11.
PAGE 42
CONTROL SYSTEM The thermostat is ON and timer is reset to normal. After 30 minutes of test run operation the system shifts to AUTO COOLING/Heating mode, and the indoor fan runs in automatic speed. The operation continues unit the EMERGENCY operation switch is pressed or a button on the remote controller is pressed, the normal operation will start. Note: Do not press the EMERGEMCY operation switch during normal operation. 11.14 AUTO RESTART Function (Option) 11.14.

CONTROL SYSTEM 11.16.4 Display of the control In the display board the lamp from left is the POWER lamp (Red), the SLEEP lamp (Yellow), the TIMER lamp (Yellow), the RUN lamp (Green) 11.16.5 When gives the control electric, the buzzer voices a long for 0.3 second per cycle. 12.17 Control logic for the heater The control logic for the heater is as follows: Condition to Cut in: If all following conditions are satisfied, the heater can operate: 1. The running time for the compressor exceeds 10 seconds. 2.
