SLEEP TIMER FUNCTION
Sleep mode, which can be used in Cool and Heat modes is a program
in the control which is designed to give a comfortable room environ-
ment during sleeping hours. At the start of sleep mode the unit will
operate in cooling or heating mode continuously until the temperature
set point is reached. It will then run for a further 1 hour period at this
setting. After this, the temperature set point will automatically be raised
+ 1° C every hour (cooling) or lowered -1°C every hour (heating) until
the sleep (shut off) time is reached. At this time the unit will shut off.
Sleep mode is set by pressing the sleep button which will set the shut
off time in 30 minute increments, starting from the time shown on the
clock when the sleep button is first pressed.
In sleep mode the unit will follow the settings that were entered at the
time that Sleep mode was started. Sleep mode can be canceled by
pressing the cancel button at any time.
DIAGNOSTIC INFORMATION FUNCTION
The control is equipped with a diagnostic information system to report
operation of the unit as well as operational failures. If your remote
control does not operate properly first check the polarity of the batteries
and that they are in good working condition. Also make sure that the
control is pointed directly at the air conditioning unit when you are using
it, that the distance is a maximum of 10 meters, and that there are no
obstacles between the remote control and the air conditioning unit.
The Diagnostic Information is reported via different flashing patterns
of the 3 indicator lights on the unit. The chart below shows the light
patterns for the various operational, protection and failure modes.
This feature is intended to provide information to the consumer as well
as for service of the units.
