F20
IGBT Power Device
Overheat Alarm
1. Check the fans are running or not.
2. Check the installation distance and space.
3. If they are OK, please replace a new compressor driver board.
4. Leave enough distance and space to make heat pump have a good transfer
heating condition.
5. Clean air to fin heat exchanger.
F22
AC input over current
protection alarm
Only in single phase unit. Restart the unit.
1. Check if there is electric leakage.
2. If still have the failure, replace a new drive board.
F23 EEPROM Fault Alarm
1. Check the connection;
2. Replace a new driver board;
F24
