2.1 RA Indoor Unit Wireless Remote Controller
In the ARC433 series remote controller, the temperature display sections on the main unit
indicate corresponding codes.
Check Method 1 1. When the timer cancel button is held down for 5 seconds, a “00” indication flashes on the
temperature display section.
2. Press the timer cancel button repeatedly until a continuous beep is produced.
The code indication changes in the sequence shown below, and notifies with a long beep.
<In case of ARC433A46, 47>
Note: 1. A short beep and two consecutive beeps indicate non-corresponding codes.
2. To cancel the code display, hold the timer cancel button down for 5 seconds. The code
display also cancels itself if the button is not pressed for 1 minute.
