Error clearing in indoor unit
Error in the indoor unit is cleared by
ON / OFF
button on the
remote controller. (Only error of the indoor unit connected
with operating remote controller is cleared.)
Clearing Error by Using Switches on the Interface P.C. Board of the Header Unit
Using the switches on the interface P.C. board of the header unit, this function is to clear the currently detected
error for each refrigerant circuit system without resetting the power supply.
Errors in both outdoor and indoor units are once cleared, and error detection is performed again.
Clearing Error by Resetting Power
This function is provided to clear error in a system by resetting the power of all the outdoor and the indoor units.
As same as the clearing method by the interface P.C. board, errors of both the outdoor and the indoor units are
once cleared, and error detection is performed again.
<Method>
(1) Be sure to reset power of both the outdoor and the indoor units.
(2) Turn on the power of the indoor unit prior to the power of the outdoor unit.
(If the power is turned on in reverse order, a check code [E19] (No. of header unit error) is output.)
NOTE
After power reset, it requires usually 3 minutes to power-on due to the initial communication of the system.
In some cases, it requires max. 10 minutes.
