(1) The function of main control
1. Time delay Safety Control
• 3min.; The compressor operation is delayed for 3 minutes to balance the pressure of cycle.
(Protection of compressor)
• 5sec.;
The indoor fan is delayed for 5 seconds, when operating initially, to prevent noises occurred by the vertical
louver and wind.
• 2min.; The reversing valve is delayed for 2 minutes to prevent the refrigerant-gas for abnormal noise when the
heating operation is OFF or switched to the other operation mode while compressor is off.
While compressor is running, it takes 3~5 seconds to switch.
2. Chaos Swing Mode
• By the Chaos Swing key input, the upper/lower vane automatically operates with the Chaos Swing or they are
fixed to the desired direction.
• While in Chaos Swing mode, the angles of cooling and heating cycle operations are different.

3. Cooling Operation Mode – 1st Stage
1) Initial start & indoor load decision stage
This stage is to decide load level of indoor and select operation compressor, which is operated according to
Table 1.
After initial start, 2nd and 3rd operating time of compressor are saved, for the purpose of selecting following
operation stage with the average value of before operated time.
- Using the average value(tm) of tm1 & tm2 and difference of outdoor temp. & desired temp., following(next)
operation stage of compressor is selected under the table 1.
- But, compressor would be restarted after 3 mins. of suspension, if it turns off.
2) If 100% compressor is selected, cooling operation-1st stage would be working.
3) If 40% compressor is selected, cooling operation-2nd stage would be working.

4. Cooling Operation - 2nd Stage
1) Condition to decide operation stage
- If Room Temp. reaches at [Desired Temp. + 0.5°C] for 2 consecutive mins. after suspension of 60% compressor operation
(<°C 3, , >), [Required time to restart 60% compressor] would be examined.
60% compressor would be restarted when [Required time to restart 60% compressor] is passed (<°C 3, >)..
The current condition would be maintained when it reaches at [Required time to restart 60% compressor], if [Required
time to restart 60% compressor] is not passed (<°C 3, >).
2) Condition to shift operation stage
1] It shifts to the Cooling Operation- 1st Stage when the operation such as of 1) is repeated in a series of 2 times.
2] 40% compressor operation would be suspended when the Room Temp. goes down to [Desired temp. – 1.0°C] after stop-
ping 60% compressor operation (<°C 3, >).
It shifts to the Cooling Operation-3rd Stage when the 40% compressor operation is suspended in a series of 2 times by
falling of room temperature after stopping 60% compressor operation.
3] It starts 60% compressor operation immediately and returns to the initial stage of Cooling Operation-2nd
Stage when the single operation time of 40% compressor pass more than 1 hour.

5. Cooling Operation - 3rd Stage
1) This operation works when the indoor load is small. The single operation of 40% compressor is performed as follows.
- The single operation of 40% compressor works when the Room Temp. reaches at [Desired Temp. + 0.5 °C].
- 40% compressor operation stops when the Room Temp. reaches at [Desired Temp. - 0.5 °C].
(But, the compressor can restart after 3 mins of compressor's off.)
2) Condition to shift operation stage
- It operates the Cooling Operation -2nd Stage when the desired temp. goes to "Desired Temp +1.0°C" more than 3 mins.
during its operation.
- It shifts to 100-40% operation after standby until 40% operation goes OFF, if the single operation of 40% compressor works
more than 1 hour.

6. Heating Operation - 1st Stage
1) Operation Condition : This stage means the 1st elapsed time which the room temperature reaches around at the desired
temperature after starting the heating operation.
- 60% & 40% compressor operations would be operated until the room temperature reaches at [Desired Temp. +0.5°C].
In other words, 100% operation would be performed.
- 60% & 40% compressor operations would be all suspended when the room temperature goes to [Desired Temp. +0.5°C].
2) Condition to decide load
: This stage performs the 100% compressor On/Off 2 times.
- 100% compressor operation would be performed when 3-minutes pass after suspension of the previous stage and
the room temperature reaches at [ Desired Temp. -0.5°C].
- 60% & 40% compressor operations would be suspended when the room temperature goes to [Desired Temp. +0.5°C].
- Criteria to decide following operation stage
a. when the average time during 2 times compressor operations is more than 360 seconds,
b. when the temperature falls more than – 3°C within 3 minutes after OFF of compressor,
c. when the outdoor temperature is under 7°C.
- It operates the heating operation -2nd stage if any condition among the above criteria would be satisfied.
