DCH DCI 37 Version - 1

10.2

Trouble shooting

10.2.1 EEPROM parameter error diagnosis and solution(E0/F4)

Error Code

E0/F4

Malfunction decision

conditions

Indoor or outdoor PCB main chip does not receive feedback

from EEPROM chip.

Supposed causes

●

Installation mistake

●

PCB faulty

Trouble shooting:

Yes

Replace the indoor/outdoor

main PCB.

Power off, then restart the

unit 2 minutes later.

EEPROM: a read-only memory whose contents can be erased and reprogrammed using a pulsed

voltage. For the location of EEPROM chip, please refer to the below photos.

Note: The two photos above are only for reference, it
