Self-diagnosis function

This function memorizes the trouble diagnosis function (Flashing LED dis­play) when trouble occurs at an indoor unit PC board. (The memory con­tents are not erased even when the power cord is disconnected from the
power outlet.)
The self-diagnosis function (LED display) allows detailed diagnosis by al­lowing switching to large division indication and small division indication.

Self-diagnosis function [LED display] (How to call memory)

(1)When trouble occurs, it is displayed by [Operation lamp (red)], [Timer

lamp (green)], and temperature monitor (7 segments display) 2 digits.

(2)After the power plug is pulled, operation starts by remote control. [Nor-

mal operation display]

(3)When the [Test run] button on the back of the remote controller is

pressed, [Memory contents] display is performed.
*When there is no error memory memorization, the unit enters the

[Test run] state.

Memory erase method

(1)The memory contents can be erased by pressing the [Service end but-

ton-emergency operation] button on the body for 3 seconds or longer
during self-diagnosis function display. (The indoor unit buzzer buzzes
for 3 seconds.)
*For 1 minute after trouble reset, the temperature and humidity moni-

tor displays [--]. After 1 minute, the temperature and humidity monitor
is displayed.
