Required by the regulation 640/2009 with regard to the application of directive 2009/125/EC on the eco-design requirements for
the electric motors.
(**) Item number imposed by regulation 640/2009, annex I2b.
(***) Description given by regulation 640/2009, annex I2b.
(****) To obtain the maximum power input for a unit with hydronic module add the maximum unit power input from the electrical data
table to the pump power input.
(†) To obtain the maximum unit operating current draw for a unit with hydronic module add the maximum unit current draw from
the electrical data table to the pump current draw.
(††) Above 1000 m, a degradation of 3% for each 500 m should be taken into consideration.
