Remote Control

The remote controller is not presetted as Cooling Only Air Conditioner or Heat Pump by manufacturer. Each time after the remote controller replace batteries or is energized, the arrowhead will flashes on the front of

Heat or Cool on LCD of the remote controller. User can preset the remote controller type depending on the air conditioner type you have purchased as follows: Press any button when the arrowhead flashes on the front of Cool , Cooling Only is set. Press any button when the arrowhead flashes on the front of Heat , Heat Pump is set. If you don t press any button within 10 seconds, the remote controller is preset as Heat Pump automatically.

Note :

If the air conditioner you purchased is a Cooling Only one, but you preset the remote controller as Heat Pump, it doesn t bring any matter. But if the air conditioner you purchased is a Heat Pump one, and you preset the remote controller as Cooling Only, then you CAN NOT preset the Heating operation with the remote controller.

Electronic Controller

1. Safety Protection

(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.

z In the “I Feel” mode, when the controller receives the up or down signal of temperature,

the set temperature can adjust by 1℃ upper or lower. The biggest you can adjust by

2℃ upper or lower.

3. “COOLING” Mode Operation

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:

RT-ST

δt come down

δt come up

4. “DRY” Mode Operation

(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)

(1) Frequency control

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

operation starts or when defrosting.
