When the air conditioner is operated in this mode the microprocessor will give priority to reducing the humidity level rather than the room temperature. (Please note that there may still be some reduction in room temperature depending on ambient conditions).
\nWhen the air conditioner is operated in the FAN MODE only the indoor fan is energised. The outdoor unit will not operate and therefore heating or cooling will not be provided. This mode is useful for circulating the air within the building.
\nThe air conditioner can be programmed to automatically turn on or off in 1 hour increments up to 72 hours in advance. It may also be programmed to turn on for a determined time then off again or vice versa provided that the last operation (ie. switch on or off) is within 72 hours.
\nIt is possible to set both the start and stop time so that the air conditioner either starts after a predetermined time and then stops after a further predetermined time or stops after a predetermined time and then starts again after a further predetermined time. This is achieved by setting both the on and off time as described above. For example if you require the air conditioner to stop in 3 hours time and then start up again 6 hours later you would program a stop time of 3 hours and a start time of 9 hours (ie. 3 + 6 hours).
\nIf you change your mind and do not want the air conditioner to automatically start or stop simply press the PROGRAM TIMER ON/OFF BUTTON (14) and the START or STOP TIME INDICATOR will extinguish.
\n| Malfunction | Measure |
|---|---|
| A ringing sound in the outdoor unit after it is started. | This sound is generated by the temperature regulator working. It will quieten down after about a minute. |
| A continuous low "shuh" sound is heard when the system is in COOLING or DEFROST OPERATION. | This is the sound of refrigerant gas flowing through both indoor and outdoor units. |
| A "shuh" sound which is heard at the start or immediately after the stop of operation or which is heard at the start or immediately after the stop of DEFROST OPERATION. | This is the noise of refrigerant stopping or changing direction. |
| Dust may blow out from the unit after starting operation from long resting time. Dust that has settled in the unit is blown out. | N/A |
| The unit absorbs the smell of rooms, furniture, cigarettes, etc., and then emits them. | N/A |
| The liquid crystal of the remote controller shows "88" | Happens immediately after the main power supply switch is turned on. Shows that the remote controller is in normal condition. Continues temporarily. |
| If a safety device such as a fuse, a circuit breaker, or an earth leakage circuit breaker frequently actuates, or ON/OFF switch does not properly work. | Measure: Turn off the main power switch. |
| If water leaks from unit. | Measure: Stop the operation. |
| If the display “ \" (INSPECTION), “UNIT No.", and the OPERATION lamp flash (2) and the "MALFUNCTION CODE" appears. | Measure: Notify your Daikin dealer and inform him/her of the display. |
| If the system does not operate at all. | • Check if there is a power failure. Wait until power is restored. If power failure occurs during operation, the system automatically restarts immediately after the power supply recovers. • Check if the fuse has blown or circuit breaker has tripped. Change the fuse or re-set the circuit breaker. |
| If the system stops operating after operating for a while. | • Check if the air inlet or outlet of outdoor or indoor unit is blocked by obstacles. Remove the obstacle and make it well-ventilated. • Check if the air filter is clogged. Clean the air filter(s). (Refer to MAINTENANCE) |
| The system operates but it does not sufficiently cool or heat. | • Check if the air inlet or outlet of the indoor or the outdoor unit is blocked with obstacles. Remove the obstacle and make it well-ventilated. • Check if the air filter is clogged. Clean the air filter(s). (Refer to MAINTENANCE) • Check if the set temperature is not proper. (Refer to OPERATION PROCEDURE) • Check if the FAN SPEED CONTROL button is set to LOW SPEED. (Refer to OPERATION PROCEDURE) • Check if the doors or the windows are open. Shut doors or windows to prevent wind from coming in. • Check if direct sunlight enters the room. (when cooling) Use curtains or blinds. • When there are too many occupants in the room. (when cooling) Cooling effect decreases if heat gain of the room is too large. • Check if the heat source of the room is excessive. (when cooling) Cooling effect decreases if heat gain of the room is too large. |
