8-5-5. When wired remote controller or indoor unit micro computer troubles
1.When the wired remote control or the indoor unit microcomputer has failed,but all other compornents work
if you set the switch (SWE, SW6) on the indoor control board, the indoor unit will begin properly
Emergency Operation.
WNote on the wireless remote control: when the remote control does not function, it is possible to
activate Emergency Operation by using the indoor unit emergency operation switch (SW1,SW2 of the
wireless signal receiver board).
However,if the indoor unit microcomputer has failed,it is nesessary to proceed with points 2 and
3 below as in the case of the wired remote controller.
2.When you activate emergency operation of the cooling or heating, you have to set the switch (SWE) and
switch (SW6) on the indoor controller.
SWE : ON • Indoor fan is running at high speed. • Drain-up machine is working.
SW6-1 : ON • Emergency operation of cooling mode.
SW6-1,2 : ON • Emergency operation of heating mode.
3.Before you activate emergency operation, check the following points:
(1) Emergency operation cannot be activated when:
• the outdoor unit malfunctions. • the indoor fan malfunctions.
• when it has detected the malfunction of drain-up machine during self-diagnosing.
(2) Emergency operation becomes continuous only by switching the power source on/off. ON/OFF on the
remote control or temperature control etc,dose not function.
(3) Avoid operating for a long time when the outdoor unit begins defrosting while emergency operation of
the heating is activated, because it will start to blow cold air.
(4) Emergency cooling should be limited to 10 hours maximum (The indoor unit heat exchanger may freeze).
(5) After emergency operation has been deactivated, set the switches etc.to their original positions.
(6) Movement of the vanes does not work in emergency operation, therefore you have to slowly set them
manually to the appropriate position.
