Uncertainty of measurement shall be as specified in EN 14511-3:2018, Table 1. The tests shall be performed

37、 at every condition stated in Tables 2 to 9, accordingly to the type of unit and in both cooling and heating mode, where applicable. For a starting test, the unit shall start and operate in the temperature conditions stated in Tables 2 to 9 during 15 min. For an operating test, the unit shall be abl
