4 – 3
[3] FUNCTION
1. Cool Operation
In the "COOL" mode, the thermostat circuit is controlled by 3 thermo-
stat lines(C1~C3).
When the difference between Room Temperature and Preset Temper-
ature is in [2]~[4] area, compressor is driving or starts driving. If [1]
area is detected, compressor will stop. And indoor fan speed is set as
following speed.
Room Temperature—Preset Temperature
Indoor fan speed
2. Dehumidification Operation
In the "Dehumidification" Mode, compressor is controlled by room tem-
perature. If it goes over D1 line and gets into the area [3], or if it lowers
than D2 line and gets into the area [1], compressor will stop.
If the evaporator temperature is lower than D3 line, indoor fan speed
will be DH and if the evaporator temperature is higher than D3 line,
indoor fan speed will be DL when the room temperature is in area [2].

3. Fan Operation
In the "Fan" mode, compressor and outdoor fan doesn’t operate.
Indoor fan motor operates as follows.
Indoor fan speed
4. Ventilating Operation
In the "Ventilation" mode, compressor and indoor fan doesn’t operate.
Outdoor fan motor operates as follows.
Indoor fan speed
5. Indoor Fan Speed
Fan speeds are given by the indoor fan motor, "DL"~"AH" which are
available in the following operation mode.
In the "COOL" or "DRY" mode, indoor fan speed is different by con-
denser temperature.
6. Overheating protection system
If the condenser temperature goes over 136.4
°
F during the cooling or
dry operation, outdoor fan speed will rise to prevent the overloading of
the compressor and restrain the rise in high pressure, and If it lowers
than 134.6
°
F, outdoor fan speed will return.
If the condenser temperature goes over 158.0
°
F during the cooling or
dry operation, compressor will stop and if it lowers than 149.0
°
F, com-
pressor will restart after 3 minutes.
