1) These errors will be automatically cleared, IF there is a COMM KIT active. Further error information can be found in the error log.
2) These errors has to be cleared by restarting the INDOOR UNIT. If the alarm reappears in the display after restarting, it means that the error is still active. Further error information can be found in
the error log.
3) These errors will probably occur due to hardware malfunction on either the COMM KIT or the EEPROM card in the OUTDOOR UNIT. It´s important to know that the EEPROM cards is different
depending on OUTDOOR UNIT size and model. For further support, please contact your installer.
4) These errors will NOT be shown in the INDOOR UNIT display, unless they happen more than 5 times during 120 minutes. Then they must be cleared in the COMM KIT display on the OUTDOOR
UNIT.
