The following checks must in any case be performed in order to calculate the maximum power consumption of the unit:
Operating supply points control Operating extraction points control
Power consumption
Hypothesis:
Unit without electric heater and set in the conservative case
of flows balanced to the flow rate and available static pres-
sure of the main flow.

The maximum supply and extraction capacity can be processed by the selected unit ENY-SP-280. In this case, the supply flow
may be considered the main one because it is the one that involves the highest consumption between the two flows.
