1.5 Fan Speed Control for Indoor Units
Control Mode Phase control and fan speed control contains 9 steps: LLL, LL, SL, L, ML, M, MH, H, and HH.
The airflow rate can be automatically controlled depending on the difference between the room
thermistor temperature and the target temperature. This is done through phase control and Hall
IC control.
For more information about Hall IC, refer to the troubleshooting for fan motor on page 177.
Fan Speed Steps In automatic fan speed operation, the step “SL” is not available.
= The airflow rate is automatically controlled within this range when the FAN setting
button is set to automatic
.
Note: 1. Fan stops during defrost operation.
2. In time of thermostat OFF, the fan rotates at the following speed.
Cooling : The fan keeps rotating at the set tap.
Heating :
The fan keeps rotating at LLL tap (FTXS, ATXS and FVXS series) or stops (the other
models).
In case of ATX20-35G
= The airflow rate is automatically controlled within this range when the FAN setting
button is set to automatic
.
Note: 1. During POWERFUL operation, fan operate H tap + 80 rpm.
2. Fan stops during defrost operation.
3. The airconditioner does not operate with MH tap from a start of the auto fan speed operation
for about 30 minutes.

- Check no 4 conduct the followings to check the electronic expansion valve ev 1 check to see if the ev connector is correctly inserted in the pcb match the ev unit number and the connector number 2 turn the power off and on again and check to see if all the evs generate latching sound 3 if any of the evs does not generate latching sound in the above step 2 disconnect that connector and check the continuity using a tester check the continuity between the pins 1 6 and 3 6 and between the pins 2 5 and 4 5 if there is no continuity between the pins the ev coil is faulty 4 if no ev generates latching sound in the above step 2 the outdoor unit pcb is faulty 5 if the continuity is confirmed in the above step 3 mount a good coil which generated latching sound in the ev unit that did not generate latching sound and check to see if that ev generates latching sound 223
- Electronic expansion valve check 223
- If latching sound is generated the outdoor unit pcb is faulty 223
- If latching sound is not generated the ev unit is faulty 223
- If the system keeps operating with a defective electronic expansion valve the following problem may occur 223
- Note please note that the latching sound varies depending on the valve type 223
