Installing a Universal Comm. Kit
2. Enthalpy sensor control
1) 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
2) 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.
‐ Can set in the 05 series installation option SEG12 (reference enthalpy default: 50 kJ/kg (21.5 Btu/lb).
3) Comparison of cooling operations depending on the enthalpy sensor availability
