31  Calculating the star rating
Products other than unitary single duct air conditioners
 (1) For section 7 of Schedule 3 and section 7 of Schedule 4, for a product other than a unitary single duct air conditioner:
 (a) the cooling star rating is based on the Total Cooling Seasonal Performance Factor (TCSPF or FTCSP) calculated in accordance with Annex B of AS/NZS 3823.4.1:2014 and derived from the use of rated values; and
 (b) the heating star rating is based on the Heating Seasonal Performance Factor (HSPF, or FHSP) calculated in accordance with clause 6.1 of AS/NZS 3823.4.2:2014 and derived from the use of rated values.
 (2) For subsection (1), calculations must be based on the residential temperature bins of clause 6.3 of AS/NZS 3823.4.1:2014 and AS/NZS 3823.4.2:2014.
Note: AS/NZS 3823.4.1:2014 has 3 cooling temperature bins, for the hot, average and cold zones. AS/NZS 3823.4.2:2014 has 3 heating temperature bins, for the hot, average and cold zones.
 (3) The TCSPF and HSPF correspond to a star rating as per Schedule 5.

Unitary single duct air conditioners
 (4) For section 7 of Schedule 3 and section 7 of Schedule 4, unitary single duct air conditioners within product class 3 or 4 must always display a star rating of zero for cooling and heating (if applicable) in all climate zones on the energy rating label or the energy rating icon, as appropriate.
