3.3.3
Operational Modes - Turning The Unit On/Off
Button T1 is used to switch the unit off (stand-by mode) or to switch the unit back on. An EPROM contained in the unit’s control board
system settings are retained when the unit is shut off or de-energized.
NOTE: If the unit will not be used for an extended period of time it should be de-energized by turning off the main power supply or pulling
the plug from the wall socket.
3.3.4 Well being key (automatic operating)
Button T2 is used to allow the unit to obtain optimal comfort in the space being conditioned. Based on the temperature of the room, the unit will
automatically set the operating mode (cooling, ventilation or heating if available), the temperature setting and fan speed.
3.3.5 Cooling Mode
In this mode, the unit dehumidifies and cools the room. Activate this mode by pressing button T4 (Run mode selector) until the snowflake
symbol D3 is displayed. The desired temperature and fan speed can now be selected. After a maximum 3 minute delay (depending when
the compressor ran last) the compressor will start, providing cooling to the space. Startup of the compressor is indicated by LED B being lit
(green).
3.3.6 Dehumidification Mode
In this mode the unit lowers the humidity level in the space. This function is very useful during the temperate months between cooling and
heating seasons, particularly on rainy days when the temperature is moderate but the humidity in the space is high, causing occupant
discomfort. In this mode room temperature and fan speed settings are ignored and as such no temperature and fan speed indications are
displayed. Activate this mode by pressing button T4
(Run mode selector) until the droplet symbol D4 and automatic ventilation symbol D1
are displayed. In dehumidification mode it is normal for the unit to function intermittently.
3.3.7 Ventilation Mode
When used in this mode the air conditioner does not perform any action with regard to temperature and air humidity in the room. Activate
this mode by pressing button T4
(Run mode selector) until the fan symbol D1 is displayed. In ventilation mode you can select the fan speed.
3.3.8 Heating Mode
This mode is only available on heating pump (HP) models. To activate heating mode press button T4 (Run mode selector) until the sun
symbol D2 is displayed. The required temperature and fan speed can be selected. After a maximum of 3 minutes the compressor should
start, and unit provides heat to the space. The start of the compressor is indicated by LED B being lit (green).
3.3.9 Defrost Mode
The unit automatically enters defrost mode from time to time to remove frost that can form on the coil. When in defrost mode, the
compressor continues to run but no heat is provided to the space as the indoor fan is shut off. When the outdoor temperature is very
low, there may be a slight delay going from minimum to maximum speed. Similar delays may occur when activating the movable baffle.
After the unit is turned off the internal fan runs for an additional 60 seconds, then stops while both air flaps close.

3.3.11 Adjusting fan speed
Fan speed can be adjusted by pressing the T5 button. Pressing this button several times changes the speed in this order: low,
medium, high and automatic. The higher fan speed provides greater the output, which also results in a higher sound level. By selecting
automatic
mode, the microprocessor adjusts the fan speed as required using the following logic: As the difference between the actual room
temperature and the user setpoint increases, so does the fan speed. As the room temperature lowers toward the setpoint, fan speed is
reduced.
NOTE: When in dehumidification mode, fan speed cannot be adjusted as the control will only operate the fan at low speed.
3.3.12 Night Mode (cooling)
To activate Night Mode (cooling), first set the operational mode to cooling and set the desired room temperature. Now press the T4 button.
Ideally night mode is selected just as you go to bed. The cooling setpoint is maintained for one hour. During the next two hours the cooling
setpoint gradually increased while the fan is run low speed. At this point the cooling setpoint no longer changes.
Press the T9 button to activate or deactivate the continuous sweeping of the air baffle. Once activated, pressing the T9 button again will
lock the baffle in placed. The allows the user to select the airflow direction best suited for their personal comfort.
Note : Never attempt to move or force the baffle by hand. Doing so will cause irreparable damage.
