Decreasing

FAN MODE
When fan speed operation is activated, various levels are available for selection: high, medium, low, automatic
ADJUSTING THE AIRFLOW DIRECTION
Use the DIREC button (airflow direction) on the remote control to adjust the direction of airflow up or down (the right-
left direction is changed by moving the flaps by hand).
AUTOMATIC AIRFLOW DIRECTION ADJUSTMENT
PRESS AUTO button
The deflector oscillates automatically, between the minimum and maximum, opering to avoid stratification effects
in heating and cooling operation modes. To interrupt automatic positioning press DIREC.
PRESS DIREC BUTTON
Press DIREC repeatedly; the deflector moves each time the button is pressed though the five set positions. If the
DIREC button is pressed and held, the settings change continuously until the button is released.
After pressing DIREC there may be short pause before the deflectors are moved to the new direction.
- Always use the DIREC (airflow direction) button on the remote control to change the up and down position of the flaps. Do not
try to set the flaps by hand, since this could cause malfunction. In the event of malfunction, switch off the FAN COIL momentarily
and then switch on again to allow the flaps to return to the correct position.
- In the cooling and dehumidifying modes, condensate could form around the unit and drip from the air outlets if the flaps have
been set in an unsuitable position for such modes. It is recommended that this position only be used for a short time.
- When the fan coil functions are not activated, the up and down flaps automatically close the air outlets.
NOTES
DEHUMIDIFYING MODE
1 PRESS THE ON/OFF button.
Fancoil is switched on and green lamp illuminates.
2 PRESS THE MODE button
Press the MODE button several times until the word DRY is displayed.
3 ADJUST THE TEMPERATURE AS REQUIRED (16°C - 30°C)
- to increase the value;
- to decrease the value;
DEHUMIDIFYING CYCLE
When the fancoil is set to this operation mode, the control system checks operation of all components automatically
to reduce air humidity. On start-up the fancoil operates in cooling mode until the set temperature is reached after which
the ON/OFF cycles are activated.
- Don't introduce fingers or other objects into the flaps, since there is high-speed fan inside the unit, which could cause injury
to persons or damage to property.
- Don't start the fancoil with the flaps locked as this could lead to malfunction.
- Don't try to set the motorised flaps by hand.
