10-1.Basic Operation

(1) When I/O button is pushed, the relays RY01,
RY02 or RY03 and power relay RY07 start ac-
cording to the conditions set by FAN SPEED knob
selector switch. Thus, the indoor fan motor and
compressor are controlled. (Operations as de-
scribed in this paragraph are all programmed. And
following items are same as it.)
(2) When the I/O button is pushed again, the relays
are all disabled, and the air conditioner stops.
(3) When the I/O button is pushed with the timer set
at any desired time, the relays are all disabled
and the air conditioner stops when the timer
reaches the set time. However, if the operation
is started with the timer set to "CONTINUE", the
operation continues.
(4) To adjust the room temperature, set the knob
mounted on the control panel at desired tempera-
ture. The room temperature sensor detects and
controls the adequate temperature.
(5) When the FAN SPEED selector switch is set to
"AUTO", the volume of air is controlled to be felt
agreeable.
