Note
• If HEAT PUMP (2WAY) type is being
used, it will beep twice and the
operating lamp will light up on the
display; if the timer and standby lamps
blink alternately, a conflict between the
heating and cooling exists, so the unit
cannot operate in the desired mode.
(On models that do not have an Auto
function, even if Auto is selected, it
works in the same way.)
• When the local operation is disabled
by centralized control or similar cause,
and if the Start/Stop
Temperature setting button
is pressed, the unit will beep five times
and the change will not be made.
