Room Temperature Sensor SettingsCommon to All ModelsThe indoor unit and the wireless remote controller are equipped withindoor temperature sensors. The sensing of indoor temperatureworks via one of them.When the unit is shipped, it is set to the indoor unit, but to switchto the remote controller, press the sensor button (diagram at right)inside the remote controller’s cover and then check to make sure thatMain Sensor on the LCD screen goes off.Even when the Sensor switch has been set to the remotecontroller, if the unit does not receive any room temperaturedata from the remote controller for ten minutes, it automaticallyswitches back to the indoor unit sensor, so be sure to installthe remote controller facing the receiver.NOTEFig. 8-108-20
