Hi everyone,

I would like to ask you about the heating capacacity table of the Daikin Althelma HT. This kind of heat pump is cascade technology and can lift the outlet temperature up to 80 Celcius. I see in the table that the rated capacity is constant while the rated power changes according to set of conditions. Would anybody can explain the reasons for it? Also, in the table, is this the data for the whole system rather than for only outdoor unit (I misunderstanding because this kind of heat pump contains two seperate heat pump units, indoor and outdoor)?

P/S: please access to the link if you want to get the data of the heat pump
