USING THE REMOTE CONTROL UNIT

HOW TO INSTALL BATTERIES

l Remove the lid in the rear part of the remote control

unit and check the settings of the dipswitch as shown below:

TEMPERATURE SENSOR SELECTOR

Under normal conditions the room temperature is detected and checked by the temperature sensor placed in the remote controller (I FEEL icon displayed ).This function is designed to provide a comfortable room temperature by transmitting the temperature control command from the location next to you. When using this function, the remote, control should always be pointed at the air conditioner, therefore it should be placed in a position in which it is visible by the indoor unit (for

example, do not put it in a drawer).

It is possible to disable the remote controller room

sensor pressing the I FEEL button. In this case the I FEEL icon on the remote controller display lights off and the sensor placed in the air conditioner becomes active.

NOTE

The remote control unit transmits signals to the indoor unit each time you press a key and at any temperature change detected by the IFEEL sensor. In case of troubles (low batteries, remote control placed in a position not visible by the indoor unit,...) room temperature control is automatically switched to the sensor of the indoor unit. In this case, the temperature around the remote control unit may differ from the temperature detected in the air conditioner position.
