E01 Remote Controller Reception Error

(when indoor unit(s) are connected)

1. Error Detection Method

It is judged an error if no self-addressed communication is sent to the remote controller in a 3-minute period.

  • When a remote controller is set to sub remote controller.
  • When there are nine or more indoor units in a remote control group´s wiring.
  • When the CHK (check pin) and/or TEST (test pin) on the indoor unit control PC board are short circuited.
  • The nonvolatile memory (EEPROM) is not installed or faulty when turning on the power.
  • Indoor unit control PC board error
  • Remote controller check mode
  • Malfunctions of the remote controller itself (reception circuit error)

3-7  Is there a short, miswiring, disconnection, wrong contact or grounding in the remote control´s wiring?  Yes Correct the wiring
No Replace the indoor unit´s control board  

 

  • The ´/´ in the table indicates the DC motor´s indoor unit board/AC motor´s indoor unit board.
  • There is no TEST pin on the AC motor´s indoor unit board.
