5. FUNCTION
5-1 Cool mode operation
In cool mode, the operation of the compressor (COMP) and fan (FAN) are determined by the difference
between the room temperature (RT) and the set point temperature (SPT) as in the graph above.
notes:
1. In this graph, the FAN is operating in the "auto fan speed" setting. If the user has selected the low,
medium or high fan speed, the FAN will run constantly at that speed only.
2. In addition to the value of (RT-SPT), the operations of the relays are also controlled by protection
delays. For example, (a) the minimum On/Off time of the COMP is 5 min and 3 min respectively,
and (b) the FAN can change speed only after it has operated at the same speed for 30 sec.
9
5-2 Dry Mode Operation (Dehumidification)
In Dry Mode, the unit operates in a mild cool mode to lower the umidity of the room. In order to maintain a high efficiency
in the drying operation without over lowering the room temperature excessively, the dry mode is different
from the Cool Mode in two ways.
1. The FAN is forced to operate at low speed only and is turned off with the COMP.
2. The unit operates in either "dry-on" state or the "dry-off" state. If RT=SPT, the unit will operate in "dry-off" state.
The COMP is forced to operate for 6 min after it has stopped working for 15 min. If RT>SPT, the unit will operate
in "dry-on" state. The COMP is forced off for 3,5 min after it has been working for 15 min.
Note 1: COMP is forced off in "dry-on" state.
Note 2: COMP is forced to operate in "dry-off" state.
5-3 Fan Mode Operation
In Fan Mode, the fan is turned on to improve the air circulation in the room. COMP remain off all the time.
Note: If the user has selected the auto fan speed setting, the FAN speed would be selected by the unit automatically according
to the difference between RT and SPT, as in cool mode.
