Press the button on the right of the unit to activate automatic mode. The display is lit according to the settings.
Buttons on the remote control 1. Automatic mode In this mode the equipment is running in cooling mode. 2. Cooling mode In this mode the room air is cooled to the preset target temperature. 3. Heating mode Heating mode is not supported. 4. Circulation mode In this mode the room air is circulated. 5. Dehumidifying mode In this mode the room is mainly dehumidified, the set temperature is maintained. "FAN" Button Press this button to set the required fan speed.
REMKO ATY Button functions A symbol is shown on the display to indicate that the settings are being transferred. ON/OFF Button Press the ON / OFF button to activate or deactivate the unit. The programmed settings and parameters are shown on the display before the unit switches off. ON/OFF / Buttons ON/OFF The remote control has its own temperature display. Press the / buttons to change the display to . The button reduces the desired target temperature, the button increases it.
AUTOMATIC Mode This mode is not supported. COOLING Mode In cooling mode the room air is cooled to the preset target temperature. The desired room temperature is set in 1 °C steps using the / buttons. If the room temperature reaches 1 °C above the set target temperature, the indoor unit starts to cool the room air. If the actual temperature falls approx. 0.5 °C below the set room temperature, the controller switches the cooling off.
REMKO ATY DEHUMIDIFY Mode In dehumidifying mode, the room temperature can be set between 18 °C and 30 °C. The low refrigerant temperature causes the air temperature at the finned heat exchanger to fall below the dew point. Any excess humdity in the air condenses in the finned heat exchanger. As a result the room is dehumidified. The fan speed cannot be altered. MODE FAN Button Press this button to set the fan speed. One can choose between low, medium, high and automatic fan speed.
SLEEP Button (hidden) Press the buttons to activate a program which will raise the target temperature in cooling mode by 1 °C and 2 °C after 1 and 2 hours respectively. SLEEP SLEEP SLEEP Diagram of function 1 hr. 2 hrs. 6 hrs. Target temperature +2°C Operation Target temperature +1°C Stop Unit operational TIMER Button (covered) This button is used to program the switch-on and switch-off times.
