☞
INDOOR FILTER CLOG, INDOOR FAN OVER LOAD, C/D WATER OVER FLOW, ROOM SENSOR TROUBLE,
HUMIDIFIER
FAULT ERROR happened, stop machine automatically. After error fixed, and then RUN switch pressed
error was reset, machine operated by one more run switch pressed.
☞ The following phenomena does not mean trouble:
(1) When room temperature is displayed LO℃ or HI℃ : This product displays room temperature between
0 40℃, and displays L℃ or HI℃ if room temperature exceeds this range.
(2) When room humidity is displayed LO%RH or HI%RH : This product displays room humidity between
30 80%RH, and displays LO%RH or HI%RH if room humidity exceeds this range.
(3) In principle the micro computer of this product is designed in the manner that two compressor
and humidifiers are installed, respectively(2 steps). For some models, however, it is designed
in the manner that one E.A of compressor and humidifier are installed, respectively(1 step).
In this case compressor and humidifier are displayed on LCD in 2 steps. For the models equipped
with each one E.A of compressor and humidifier, compressor or humidifier is operating in one
step if one of compressor 1 or 2, or one of humidifier 1 or 2 operates. If the machine used
three E.A of compressor, operation condition displayed on LCD in 3 steps. In case of used AHU
controller, displayer 4 step.
