3.3.11 Test Run by Wireless Controller (CIR01)
After all installations are completed, a test run should be performed.
(1) Perform the test run according to the Installation Manual of the wireless controller.
(2) The test run from the wireless controller switch takes two hours to complete.
NOTE:
For the wall mount indoor units, if the TIMER indicator (green) is ashing (0.5 second ON/0.5 second
OFF) after two hours, an alarm may occur. Operate the indoor unit ,and check for abnormality.
3.3.12 Alarm Indication
● If a malfunction occurs, such as safety device actuation, during the test run or the normal
operation, “RUN” (red light) ashes (0.5 second ON / 0.5 second OFF).
● The alarm codes are indicated by the number of LED ashes of “DEF” (green light) and “FILTER” (yellow
light).
The rst LED light is green. The number of times this LED ashes (0.5 second ON and
OFF) will tell you the “DEF” Alarm Code.
The second LED light is yellow. The number of times this LED ashes (0.5 second ON and
OFF) will tell you the “FILTER” Alarm Code.
Example
● ”RUN” (red light) ashing (1 second ON/1 second OFF) indicates an abnormal transmission (connector
loose, connector disconnection, broken wire, or incorrect wiring, or something similar) between the
indoor unit and the IR receiver kit.
● When the IR receiver kit is connected to multiple indoor units, the alarm code is indicated for each
indoor unit in order.
