Electronic Controller

(1) Time Delay for Safety protection z 3 minutes delay for compressor ---The compressor is ceased for 3minutes before restarting to balance the pressure in the refrigeration cycle in order to protect the compressor. z 2 minutes delay for 4-way valve---The 4-way valve will be ceased for 2 minutes late after compressor to prevent the refrigerant-gas abnormal noise when the HEATING operation is OFF or switch to the other operation mode.

(2) Discharge temperature protection

There is a temperature sensor on top of compressor, when temperature on top of compressor exceeded the limit, system control will shut down the compressor and the display board will show the error code.

(3) lower voltage protection

When AC voltage ≤158V and keep it for 10 seconds, unit will be shut down for protection.

(4) Over voltage protection

When AC voltage ≥260V, unit will be shut down and recover while AC≤255V.

(5) Over current protection

When the current of outdoor unit is overload, controller shut down the unit immediately and show error code.

(6) Compressor abnormity protection

When compressor start on or in the process of running, if there is no feedback to controller or load of compressor is abnormity, the air conditioner will shut down, and show error code.

(7) IPM module protection

IPM module has high temperature & over current protection itself, if there is signal feedback to IPM, the outdoor unit will shut down, LED on outdoor PCB will show the error code.

2. “I Feel” Mode Operation

(1) When the “I Feel” mode is selected, the operation mode and initial temperature set are determined by the initial room temperature at start-up of the operation except to turn off the air conditioner and operates it again.

(2) If the mode is change to “I Feel” from other mode, the “I Feel” mode doesn’t operate until compressor stop for more than 3 minutes.

TCL Air Conditioner Service Manual

(1) Compressor frequency control

According to difference room temperature and set temperature(δt = RT-ST), running frequency of compressor is controlled by electronic controller. When room temperature is much higher than set temperature, compressor will start at a high frequency, and as room temperature goes down, compressor running frequency will go down. When room temperature is lower than set temperature, compressor will run at very low frequency. In general, unit will change its running frequency according toδt to make room temperature closing to set temperature.

(2) Outdoor temperature affects running frequency of compressor

Outdoor temperature affect compressor’s running frequency. Difference inlet temperature of outdoor unit is adapted by difference compressor running frequency. While outdoor temperature is about 30℃, the compressor will run in high frequency.

If unit run in “cooling” mode and outdoor temperature is less than -1℃,controller will shut down compressor and show error code, while the ambient temperature is over 0℃, the compressor will run automatically.

(3) Auto fan control in cooling mode

In cooling mode (include cooling in “I feel” mode), fan speed is determined by δt, as the following diagram:

(1) The system for DRY operation used the same refrigerant circle as the cooling one.

(2)

When the system operates in DRY mode, at first it operates in cooling mode at 16℃ or

18℃ for 3 minutes. After that, the system will operate in cooling mode with lowest fan speed, meanwhile the set temperature (ST) is “RT-2℃” which means that the ST is room temperature at then minus 2. During the course of this mode, the fan speed set operation and room temperature set are restricted, except the vane motor adjusting.

5. “HEATING” Mode Operation (available for Heat Pump only)

The same as the frequency control in cooing mode, running frequency of compressor is controlled by controller. Unit change its running frequency according to δt to make room temperature closing to the set temperature.

(2) Indoor fan motor control

1. Cold Air Prevention Control z The function is intended to prevent cold air from being discharged when the heating operation starts or when defrosting. z The indoor fan speed will be controlled as following.

In heating mode, 4-way valve will power on ahead of compressor for 5 seconds, and cut off for 2 minutes later than compressor’s stop. 4-way valve will not power off unless the machine is switched off, mode changed or on the process of defrosting.

(4) Defrosting

Defrosting is controlled by the microprocessor.

When one of the following conditions is satisfied, unit will come into defrosting: a. Outdoor heat exchanger Temperature (OPT) is continuously less than 3℃ while the unit runs for more than 40 minutes, and OPT is keeping under -6℃ for more than 3 minutes. b. Outdoor heat exchanger Temperature (OPT) is continuously less than 3℃ meanwhile the unit runs for more than 80 minutes, and OPT is keeping under -4℃ for more than 3 minutes. c. Outdoor heat exchanger Temperature (OPT) is continuously less than 3℃ while the unit runs for more than 120 minutes, and OPT is keeping below -2℃ for more than 3 minutes.

Before the air con come into defrosting, compressor running frequency drop down to a lower frequency firstly, then the compressor shuts down.

In defrosting, the max. frequency of compressor is F9 (a little less than the highest frequency ). In this period all protection function are avaliable.

5) Indoor exchanger overheat protection

When Indoor exchanger Temperature(IPT) is higher than 55 ℃ , unit come into indoor exchanger overheat protection. Compressor drop its frequency toward to F1 level until IPT≤52

℃; If IPT≤52℃ and keep for 5 minutes , control system don’t limit running frequency.

If IPT>62℃, control system shut down compressor, and recover when IPT drop less than 50℃.

6. “SLEEP” mode

When the SLEEP button is pressed, the SLEEP mode is selected as following: z The indoor fan speed is set at low speed, the power lamp and the sleep lamp is on, the display of temperature will be close after 5 minutes.

z When selecting COOLING/DRY operation with SLEEP mode, the set temperature will be raised by 1℃ 1 hour later and by 2℃ 2 hour later. z When selecting HEATING operation with SLEEP mode, the set temperature will be dropped by 1℃ 1 hour later and 2℃ 2hour later. z After the System operates in SLEEP mode for 8 hours, it will stop automatically.

7. EMERGENCY Operation

When the EMERGENCY Operation switch is pressed once, COOLING mode is selected and if in 3 seconds the EMERGENCY Operation switch is pressed again, mode is selected. Then pressed once again, the unit is switch off.

When the remote controller is missing, has failed or the batteries run down, press the

EMERGENCY Operation switch on the front of the indoor unit. The unit will start.

The first 30 minutes of operation will be the test run operation. The operation is for servicing.

The indoor fan runs at high speed and the system is in continuous operation. The thermostat is

ON and the 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.

8. AUTO-RESTART Function (Option)

1. When air conditioner is operating in one mode, all of its operation data, such as working mode and temperature of setup would be memorized into IC by main PCB. If power cuts due to

8

TCL Air Conditioner Service Manual some reason, when power supply come back again, the AUTO-RESTART function will set synchronously and automatically to work. So the air conditioner would work at the same mode before.

Auto-restart Pre-setting (optional)
