The system of the Lossnay unit and Dx-coil unit is designed to maintain the return air temperature close to the setting
temperature.
[SA (Supply Air) temperature control]
The system of the Lossnay unit and Dx-coil unit is designed to maintain the supply air temperature close to the setting
temperature.
GUG-01SL-E cannot be used for SA temperature control.
The setting temperature is recommended to be the same as or close to the setting temperature of the air conditioning unit.
