FILTER CARE AND FILTER ALARM
To keep your air conditioning unit in peak condition, the filters should be cleaned regularly, i.e. once a month, or more
frequently depending on conditions. To do this;
- Remove the filters from the unit
- Wash them in soapy water (do not use detergent)
- Dry the filters and put them back in place on the unit.
To clean the unit casing, use a damp cloth.
The control is equipped with a filter Alarm; based on the hours of operation, and indicated by all of the lights flashing
(see the Diagnostic Chart for details), to remind you to change the filter. To reset the alarm press the Filter button on
the remote control. If you fail to press the reset button the alarm will automatically reset after 6 hours of operation.
CLOCK AND TIMER FUNCTIONS
To set the clock press the Clock button for at least 5 seconds, until the Clock symbol flashes. Then use the timer
buttons to set the desired time. Finally, press the Clock button again to enter the time that has been set.
The control is equipped with a timer that can set both start and stop times for the unit. The operational settings that
have been entered on the control will be the ones that the control follows when it starts.
To use the timer function follow these steps;
START
1. Turn the unit on.
2. Press the start button
3. Adjust the clock display to the desired start time
4. Press Enter
The START symbol will be shown on the display,
indicating that a start time has been programmed.
Lights will indicate that the unit timer has been set.
After the unit has either been started or stopped by the timer, the set time will remain in the program, however the
start or stop button must be pressed again to reset the timer function.
To cancel either the Start or Stop Timer setting press the Cancel button. To check the time that has been entered
either for starting or stopping the unit, press the appropriate start - stop button and the time will be displayed. Press
the button again to go back to the clock display.
SLEEP TIMER FUNCTION
Sleep mode, which can be used in Cool and Heat modes is a program in the control which is designed to give a
comfortable room environment during sleeping hours. At the start of sleep mode the unit will operate in cooling or
heating mode continuously until the temperature set point is reached. It will then run for a further 1 hour period at
this setting. After this, the temperature set point will automatically be raised + 1° C every hour (cooling) or lowered
-1°C every hour (heating) until the sleep (shut off) time is reached. At this time the unit will shut off.
Sleep mode is set by pressing the sleep button which will set the shut off time in 30 minute increments, starting from
the time shown on the clock when the sleep button is first pressed.
In sleep mode the unit will follow the settings that were entered at the time that Sleep mode was started. Sleep mode
can be canceled by pressing the cancel button at any time.
DIAGNOSTIC INFORMATION FUNCTION
The control is equipped with a diagnostic information system to report operation of the unit as well as operational
failures. If your remote control does not operate properly first check the polarity of the batteries and that they are in
good working condition. Also make sure that the control is pointed directly at the air conditioning unit when you are
using it, that the distance is a maximum of 10 meters, and that there are no obstacles between the remote control
and the air conditioning unit.
The Diagnostic Information is reported via different flashing patterns of the 3 indicator lights on the unit. The chart
below shows the light patterns for the various operational, protection and failure modes.
