  • Checking the power
    If nothing appears on the remote controller’s display, turn on the circuit breaker.

  • Setting the current time

DAIKIN-BRC944B2-Room-Air-Conditioner-fig- \(5\)

Notes
To use the unit efficiently

  • Avoid overcooling or overheating. Moderate room temperature setting contributes to power saving.
  • Recommended temperature setting
    • For cooling ·············· 26~28°C (79°F~82°F)
    • For heating ············· 20~22°C (68°F~72°F)
  • Hang a blind or a curtain on the window. This will enhance the cooling/heating effect by intercepting direct sunlight and drafts.
  • A clogged air filter reduces the cooling/heating effect and wastes energy. Clean the air filter monthly (every two weeks as required) or so.

Please take note of the following points

  • Electric power is consumed even when the air conditioner is not in operation.
  • When the unit is not used for a long period of time such as during off-season, turn off the breaker.

Operating conditions
If the operation is continued under any conditions other than the following, the safety device may work to stop the operation.

Also, dew may form on the indoor unit and drip from it. (Cooling/DRY)

Cooling| Outdoor temp. -10 to 46°C (14°F to 115°F) Room temp.        18 to 32°C (64°F to 90°F) Indoor humidity Less than 80%
---|---
DRY| Outdoor temp. -10 to 46°C (14°F to 115°F) Room temp.        18 to 32°C (64°F to 90°F) Indoor humidity Less than 80%
Heating| Outdoor temp.  -15 to 20°C (5°F to 68°F)
Room temp.       Less than 27°C

Operation limit differ according to the model.

Preparation before Operation

Setting Temperature Indication change
Temperature indication can be changed between Celsius and Fahrenheit before use.

To change from Celsius temperature indication to Fahrenheit one To change from Fahrenheit temperature indication to Celsius one

Notes
Temperature indication change between Celsius and Fahrenheit on the remote controller

  • Change the temperature indication in the modes other than the DRY mode.
  • In the DRY mode, temperature indication setting cannot be changed because the temperature is not indicated.
  • When the Fahrenheit temperature indication is changed to Celsius one, the temperature value (0.5°C) will be rounded up. Thus, the preset temperature may be changed.
  • Example: A preset temperature of 65°F (equivalent to 18.5°C) will be changed to 19°C (66°F) by changing the temperature indication. In this case, if you change the Celsius temperature indication again to the Fahrenheit one, the preset temperature is shown not as 65°F but as 66°F (equivalent to 19°C). If the preset temperature is 66°F (equivalent to 19°C) and is changed to the Celsius temperature indication, the indication becomes 19°C (66°F). In this case, no change by the temperature indication change is observed.
  • When the temperature indication change is set, the preset temperature is transmitted to the indoor unit so that the reception sound will be heard from the indoor unit.

Automatic · DRY · Cooling · Heating Operation

Once preset, the system can get restarted in the same operation mode.DAIKIN-
BRC944B2-Room-Air-Conditioner-fig- \(9\)

To stop the operation:

  • Press again.
  • The run indicator lamp goes out.

Automatic operation
In Automatic, the temperature setting and operation mode (DRY, Cooling or Heating) are automatically selected according to the room temperature and outdoor temperature at the time of starting operation.

DRY operation
In this mode, humidity is removed from the air.

Note
While running in the DRY mode, you may feel cool or warm air from the air outlet. In this case, readjust the airflow direction with the vertical airflow direction louvers. (except Duct Connected type)

To adjust the temperature and airflow rate:DAIKIN-BRC944B2-Room-Air-
Conditioner-fig- \(11\) When the unit runs in the cooling or heating mode at a low airflow rate, the cooling or heating effect may be insufficient.

To adjust the airflow direction:( page 9)

Heating operation

  • Since the heating operation is performed by taking the heat from outdoor into the room, the heating capacity decreases as the outdoor temperature lowers. If the room is not heated sufficiently, it is recommended to use other heating appliance at the same time.
  • Since the air conditioner heats the whole room by circulating hot air, it takes some time to heat the entire room completely.
  • If the outdoor unit gets frosted during heating operation, the heating capacity is decreased. In this case, the unit starts defrosting operation.
  • No hot air comes out of the indoor unit during defrosting operation.

Adjusting Airflow Direction

Adjust the airflow direction for maximum comfort.

To adjust the Airflow Direction

  1. Press during operation.
    Each time the button is pressed, the airflow direction louvers change their movement. DAIKIN-BRC944B2-Room-Air-Conditioner-fig-

Wall Mounted Types (without horizontal swing function)

  • The horizontal airflow direction louvers move up and down.
  • The louvers stop just when the button is pressed.

Adjustment of horizontal airflow direction
The automatic moving range of the horizontal airflow direction louvers varies depending on the operation mode.

Notes

  • In fixing the horizontal airflow direction, keep the horizontal airflow direction louvers tilted downward in the heating mode, and keep them nearly horizontal level in the cooling or DRY mode. This will enhance the cooling and heating effect.
  • On the air conditioners with vertical and horizontal swing function, be sure to adjust the airflow directions using the remote controller. Do not forcibly adjust louvers by hand or a malfunction may occur.

Wall Mounted Type (with horizontal swing function)

  • The horizontal airflow direction louvers move up and down.
  • The horizontal airflow direction louvers stop just when the button is pressed. Then the vertical ones start moving right and left.
  • The vertical airflow direction louvers stop just when the button is pressed.

The vertical and horizontal louvers cannot move at the same time.
