Installing a Universal Comm. Kit
2. Enthalpy sensor control
ߣ࣒
Operate the product after comparison between the intake enthapy of indoor unit and reference
enthalpy.
ࣞ
Reference enthalpy (installation option code; selectable according to the site)
ࣞ
Cooling Thermo OFF & (enthalpy > reference enthalpy): Cooling T-ON
ߤ࣒
The reference enthalpy for cooling T-ON can be set depending on the site.
ࣞ
If it is required to keep a lower humidity, decrease the reference enthapy. For a higher humidity,
increase the reference enthalpy.
