Example of commissioning
Below is an example of selection of the machine that can help to explain calibration:
The aim here is to install a primary air ventilation system with very high thermal recovery perfor-
mance in an average-sized store.
The ventilation unit is to be inserted in a 4-pipe central air conditioning system provided by the
owner and used for water terminals.
The store is located in a climate area characterised by cold winter temperatures (climate area E,
design temperature -8°C).
Primary air is to be used as the energy carrier for summer air conditioning.
The design data for selection of the machine are summarised below:
On the basis of the calculated flow rate, the Energy Plus model is selected as the most suitable,
together with all the necessary accessories.

After selecting the most appropriate model in the Energy Plus range, it is possible to identify the
parameters for correct calibration of the machine and, therefore, the characteristic performance
parameters.
The control voltage at which to control the EC fan motors depends on:
• Model =
ENY-P3
• Antifreeze resistance =
EXTERNAL
• Cooling water coil =
