(5) Dehumidification 

※

If reheat coil and humidity sensor (Optional) is equipped:

The unit have dehumidification control by a reheat coil, which is under the evaporator coil.  To execute
dehumidification, controller setting is required.  (Refer to Page 3-12)
In dehumidification, the Reheat Solenoid Valve (RSV) opens to give high pressurized refrigerant to
reheat coil.  The "DEHUMID" LED lamp will light up.
The following setting can be made:
1) Non bumidification control
2) Humidification control (OPTION)

Dehumidification range: 30%RH–95%RH
