Page 10: Correction Of The Heating Capacities
CORRECTION OF THE HEATING CAPACITIES in the heat pump operation (heating mode), the actual heating capacities of units may be lower than the values shown in the tech- nical data table, due to the different values of the relative humidity of the external air. To obtain the actual heating capacity, multiply the capacity values by the corrective coefficients given in graphic. -
