How to Respond
3 This is not a malfunction.
The blower is operating just for cooling down the
heated-up air conditioner. This will be done within
1 minute.
This control is conducted only when the HEAT
operation is stopped with the electric heater ON.
1 If the up/down vane is set to downward in COOL
operation, it will be automatically set to horizontal
blow by the microprocessor in order to prevent
water from dropping down.
"1 Hr." will be displayed on the remote controller
if the up/down vane is set to downward with the
fan speed set to be less than "LOW".
2 In HEAT operation, the up/down vane is auto-
matically controlled according to the temperature
of the indoor unit's heat exchanger.
In the following cases written below, the up/down
vane will be set to horizontal blow, and the set-
ting cannot be changed by remote controller.
1) At the beginning of the HEAT operation
2) While the outdoor unit is being stopped by
thermostat or when the outdoor unit gets start-
ed to operate.
3) During DEFROST operation
The airflow direction will be back to the setting
of remote controller when the above situations
are released.
3 1) Check if the vane is set to a fixed position.
(Check if the vane motor connector is removed.)
2) Check if the air conditioner has a function for
switching the air direction.
3) If the air conditioner does not have that func-
tion, "NOT AVAILABLE" will be displayed on
the remote controller when "AIR DIRECTION"
or "LOUVER" button is pressed.
1 Check if you set ON/OFF timer.
The air conditioner starts operating at the time
designated if ON timer has been set before.
2 Check if any operations are ordered by distant
control system or the central remote controller.
While "CENTRALLY CONTROLLED INDICATOR"
is displayed on the remote controller, the air con-
ditioner is under the control of external directive.
3 Check if power is recovered from power failure
(black out).
The units will automatically start operating when
power is recovered after power failure (black out)
occurs. This function is called "auto recovery fea-
ture from power ".
1 Check if you set ON/OFF timer.
The air conditioner stops operating at the time
designated if OFF timer has been set before.
2 Check if any operations are ordered by distant
control system or the central remote controller.
While "CENTRALLY CONTROLLED INDICATOR"
is displayed on the remote controller, the air con-
ditioner is under the control of external directive.
