Remote control
The remote control will work at a distance of approximately 3 metres to 600 metres, however this can be greatly reduced by obstacles (buildings, etc.). Hold the aerial -4- upright and do not cover the aerial with your hand.
The LED -3- indicates if the auxiliary heating/ventilation cannot be switched on/off.
- If the LED flashes slowly in red, the remote control is out of range.
- If the LED flashes rapidly in red, the conditions for operation have not been met or a fault has occurred.
- If the LED does not flash, the remote control battery is flat.
Timer
Three timers are available; only one can be activated at a time. When the time set on one of the timers elapses, the date automatically changes to the next day. The desired timer must be activated again the next time you wish to use the auxiliary heating/ventilation. This prevents the system from switching on unintentionally.
Note
The auxiliary heating/ventilation is NOT switched off when you press the OFF button on the air conditioner console. The OFF button just switches the blower on/off.
