(1) Compressor control
13-minute time delay
To prevent overload, the compressor will not start within 3 minutes after stop.
2The compressor runs when the room temperature displayed on remote controller
is higher than the set temperature.
The compressor stops when the room temperature displayed on remote controller
is equal to or lower than the set temperature.
3The compressor stops in check mode or during protective functions.
4The compressor will not start when the room temperature displayed on remote controller
is below 64°F.
The compressor starts intermittent operation when the power is turned ON with room temperature above 64°F. The com-
pressor ON/OFF time depends on the thermostat ON/OFF and the following room temperatures.After 3-minute compres-
sor operation,
● If the room temperature thermistor reads above 82°F with thermostat ON, the compressor will operate for 6 more min-
utes and then stop for 3 minutes.
● If the room temperature thermistor reads 79°F—82°F with thermostat ON, the compressor will operate for 4 more min-
utes and then stop for 3 minutes.
● If the room temperature thermistor reads 75°F—79°F with thermostat ON, the compressor will operate for 2 more min-
utes and then stop for 3 minutes.
● If the room temperature thermistor reads below 75°F with thermostat ON, the compressor will stop for 3 minutes.
● If the thermostat is OFF regardless of room temperature, the compressor will stop for 10 minutes.
5Coil frost protection in DRY operation is the same as in COOL operation.
6Coil frost prevention does not operate in DRY operation.
(2) Indoor fan control
The indoor fan runs on LOW speed during compressor operation. The fan speed cannot be changed with the remote con-
troller. Also, the indoor fan does not run during compressor OFF.
(3) Auto vane & drain pump controls
Same as in COOL operation
(4) Detecting abnormalities in the outdoor unit
