Owner’s Manual 4 Operating Instructions Regarding the Airflow of the Indoor Unit Filter The air that is pulled in by the fan (the “return air”) enters the grille and is passed through the filter. It is then cooled/dehumidified/heated through the heat exchanger. Heat The direction of the air output is manipulated up and down by the motorized louver, and left to right via manually controlled vertical deflectors.
4 COOLING Mode Cooling mode allows the air conditioner to cool the room while also reducing the humidity of the air in the room. To put the system into cooling mode, press the button until the symbol appears on the remote’s display. The and buttons can then be used to set a temperature lower than that of the room. HEATING Mode Heating mode allows the air conditioner to heat the room. To put the system into heating mode, press the button until the symbol appears on the remote’s display.
Owner’s Manual Operating Instructions DRY Mode Dry mode is a limited function that can help reduce the humidity/moisture of the room. To put the system into dry mode, press the button until the symbol appears on the remote’s display. An automatic preset of this mode is then activated. FAN-ONLY Mode Fan-only mode is used to set the system to use only air ventilation and no heating or cooling. To put the system into fan-only mode, press the button until the symbol appears on the remote’s display.
4 Turning the Display On or Off The LED display on the front panel of the system can be turned on or off as desired. To do so, press the button in order to switch off the LED display on the front panel. This button can be pressed again to turn the LED display back on. SLEEP Mode Sleep mode is generally meant for periods of lower cooling requirements, such as during typical sleeping hours. This mode will result in decreased energy use, and can only be activated via remote control.
Owner’s Manual Operating Instructions Energy Saver (ECO) Option In this mode, the appliance will automatically manage the operation in order to save energy. To turn the ECO feature on, press the button on the remote, and the icon will appear. The system is now running in ECO, and the process can be repeated to turn it off. NOTE The ECO feature is available in both COOLING and HEATING modes.
4 Using the Timer - TIMER ON The TIMER feature allows you to set a time delay for the system to turn itself on or off. To set a time delay for the system to turn itself on in X number of hours: 1. Begin by pressing the button while the system is powered off. The symbol will then display. You can then set the needed modes. 2. Set the desired mode (COOL, HEAT, AUTO, FAN, DRY) by pressing the button. 3. Set the desired fan speed with the button. 4.
Owner’s Manual Operating Instructions 46°F Freeze Protection Function This feature is meant to be used to prevent freezing while the user is away from home. When turned on, it sets the system to keep a temperature of 46°F. If the unit is in standby, then the setting will automatically start the heating mode when the room temperature is equal to or lower than 46°F. It will set the system back to standby when the room temperature reaches 48°F.
4 I FEEL - To Ensure Comfort The I FEEL feature enables the remote to act as the temperature sensor and relay the current air temperature of where the remote is physically placed within the room. In some cases, this can aid with reducing thermal drift between the set temperature and the actual room temperature. In order to activate this feature, press the button, and the icon will appear on the display. Note: The I FEEL feature will automatically de-activate itself 2 hours later.
Owner’s Manual 4 Operating Instructions An Important Note Regarding Operating Temperatures The system is designed to run within a certain range of temperatures, which are listed below.
