Division 2 The determination of the seasonal energy consumption and efficiency for seasonal energy efficiency ratio (SEER) and seasonal coefficient of performance (SCOP) shall take into account:

European cooling and heating season(s), as defined in Table 1 below;

reference design conditions, as defined in Table 3 below;

electric energy consumption for all relevant modes of operation, using time periods as defined in Table 4 below;

effects of the degradation of the energy efficiency caused by on/off cycling (if applicable) depending on the type of control of the cooling and/or heating capacity;

corrections on the seasonal coefficients of performance in conditions where the heating load can not be met by the heating capacity;

the contribution of a back-up heater (if applicable) in the calculation of the seasonal efficiency of a unit in heating mode.
