Whenever there is a problem with the system, an error code will be dis- played on the front cover of the indoor unit. If more than one error has occurred, the codes will alternate so that all codes are shown. Make note of the code (E4, F6, H4, etc.), then reset the display by pressing the ON/OFF button on the wireless remote. Press the ON/OFF button a second time to reapply power to system. If code is still displayed, dis- connect and restore power at the unit disconnect switch or circuit breaker. If the problem was temporary, the code will not reappear. If the error code reappears after power has been restored, contact your HVAC contractor.
