(1) Compressor control
1
3-minute time delay
To prevent overload, the compressor will not start within 3 minutes after stop.
2
The compressor runs when the room temperature is lower than the set temperature.
The compressor stops when the room temperature is equal to or higher than the set temperature.
3
The compressor stops in check mode or during protective functions.
4
Overheat protection
<Start condition>
When the indoor coil thermistor reads 158°F or above, the overheat protection will start.
<Overheat protection>
The compressor stops for 6 minutes, and then restarts.
If the start condition is satisfied again within 10 minutes of compressor operation, both the indoor and outdoor units stop,
displaying a check code of “P6” on the remote controller.
<Termination conditions>
Overheat protection is terminated when the start condition is not satisfied again during the allowance (10-minute compres-
sor operation), when operation mode changes to other mode, or when thermostat turns OFF.
(2) Indoor fan control
(a) Normal control
( i )The indoor fan runs on LOW speed during the thermostat OFF.
LOW speed can be changed to HIGH speed by setting the dip switch SW1-6.
If the indoor coil temperature becomes more than 5 degrees below the room temperature during the thermostat
OFF, the indoor fan will stop. After, when the indoor coil temperature becomes within 5 degrees of room tempera-
ture, the indoor fan will run on LOW speed.
( ii )Hot adjustment
Hot adjustment is a warm-up for HEAT operation
<Start conditions>
The hot adjustment works under any of the following conditions.
●
HEAT operation starts.
●
Defrosting ends.
●
Thermostat turns ON.
[Hot adjustment]
Initially, the indoor fan runs on LOW speed. When 5 minutes have passed or the indoor coil temperature exceeds
95°F, the fan speed will not be changed. 2 minutes later, the hot adjustment ends. Then, the fan speed depends on
the remote controller setting.
(iii)The indoor fan stops when the indoor coil temperature is within 9 degrees either way of room temperature.
(iv)To eliminate the remaining heat, the indoor fan runs for the first 1 minute after the booster heater is turned OFF.
