Where the outlet temperatures set out in column ‘variable outlet’ are to be applied for heat pumps that control the outlet (flow) water temperature according to the heat demand. For heat pumps that do not control the outlet (flow) water temperature according to the heat demand but have a fixed outlet temperature, outlet temperature should be set according to the ‘fixed outlet’.

Medium temperature corresponds to high temperature in EN 14825:2013.
For fixed capacity units, tests are applied as indicated in EN 14825:2013, section 8.4. Either the outlet temperatures during the tests are the ones to obtain the average outlet temperatures corresponding to the declaration points in EN 14825:2013 OR this data should be obtained by linear interpolation / extrapolation from the test points in EN 14511-2:2013, complemented with test at other outlet temperatures when necessary.
For variable capacity units, EN 14825:2013 section 8.5.2 are applied. Either the conditions during the tests are the same as for the declaration points specified in that standard OR tests can be performed at other outlet temperatures and part load conditions and the results linearly interpolated, extrapolated, to determine the data for the declaration points in EN 14825:2013.
Apart from test conditions A to F, ‘in case the TOL is below – 20 °C, an additional calculation point has to be taken from the capacity and COP at – 15 °C conditions’ (cit. EN 14825:2013 § 7.4). For the purpose of this communication, this point will be called ‘G’.
