7 LOCKING/UNLOCKING THE REMOTE CONTROL UNIT

To lock the remote command unit, the HL parameter value must

be set as YES.

With the remote command unit locked, the following operations

are not allowed:

▶

setting the default parameters

▶

setting the remote command unit operating mode

▶

displaying the fan speed

▶

displaying the detected temperature and humidity

▶

Programming the setpoint

▶

programming the current time

▶

programming the ON/OFF periods

When the remote control is locked, display shows “loc” when

pressing any key.

To temporarily unlock the remote control unit, hold the

button pressed until the display shows "OFF". The remote control

unit returns automatically to locked status after 15 sec.
