It is also

It is also not completely transparent since it describes (ANNEX C) the reference heating/cooling demand and the number of hours in each operational mode (active mode, thermostat off mode, standby and crankcase heater mode) is decided from weighted climate, type of building, internal gains, set back setting and so on, but there is no reference that describes the calculations. Therefore it is not possible to recalculate the hours to fit specific needs. The climate hours that describes the temperature bins does not seem to be adjusted in any ways since it is the same hours that is used in Ecodesign LOT 1.
