(17) Heating operation overload protection (40 type only)
During heating operation in overload condition (room outside air temperature is considerably high), in order to protect the unit, the
outdoor fan is controlled by the pressure switch (63H).
(a) Outdoor fan control
High pressures are prevented and extreme heat absorption controlled by turning the outdoor fan ON and OFF with the pressure switch.
(18) High power operation (Remote controller "HI POWER" button on)
The indoor unit fan rotates at speed 4 for 15 minutes, and carries out continuous cooling and heating.
(19) Economy operation (Remote controller "ECONO" button on)
(a) Cooling economy operation
The indoor unit fan operates 2°C higher than the set temperature at speed 1.
(b) Thermal dry economy operation
Thermal dry operation carried out at 2°C higher than the set temperature.
(c) Heating economy operation
The indoor unit fan operates 2°C lower than the set temperature at speed 2.
(20) Self diagnosis function
When something abnormal happens on the outdoor unit, indoor unit fan motor and each thermistor (heat exchanger, room tempera-
ture,) it will be indicated by flashing lamps.
(a) Abnormality of outdoor unit: TIMER lamp will flashing when 5 minutes after it has been operated with the compres-
(b) Abnormality of indoor fan motor: When the indoor fan motor goes ON during air conditioner operation, if the fan
(c) Abnormality of heat exchanger thermistor: RUN lamp will flashing when the input temperature of the heat exchanger
(d) Abnormality room temperature thermistor: RUN lamp will flashing when the input temperature of the room tem-
Note (1) If the above abnormalities happen concurrently, the lamp will flashing in the order of item number (a) through (d) above.
