How to select the optimal Ventilation Speed
The fine tuning of the Ventilation Speed can be done properly modifying the following parameters:
• Initial fan speed: High or Ultra-High
• Supply fan step setting: Step 1 to 15
• Exhaust fan step setting: Step 1 to 15
These parameters can be accessed following the procedure The Configuration Service Settings
Both Supply and Return Fans have an optimal speed value, described in term of RPM (Revolution per Minute), that can be retrieved directly from the DAE Unit Selection Software report,
as shown below:

Optimal RPM values for Supply and Return (Exhaust) Fans
Provided the Unit Size is known, you can proceed to set the correspondent Supply/Return Fan step on the BRC controller, according to the following Speed-selection Tables (Make sure
to consider "Heat recovery operation" rpm).
If you do not have the unit selection from Daikin tool software, please check individual unit size performances from
Speed-selection tables
In order to select the correct step for the Supply and Return Fan it is necessary to:
• Choose the table whose Unit Size number equals the Unit Size provided in the DAE Unit Selection software report.
• Identify the Supply/Return Fan steps by choosing, from H(high) column, the steps whose RPM values are the closest to the Supply/Return Fan RPM provided by DAE Unit Selection
software report.
• Set the selected step values on the controller by going to the path Service Settings
- 19(29)-2- Selected_Step_Supply_Fan, for the Supply Fan Step, from 01 to 15
- 19(29)-3- Selected_Step_Return_Fan, for the Return Fan Step, from 01 to 15
• If both Supply and Return Fan RPM are not present in the column H, but they appear in UH (ultra high) one, then:
• Set the Initial Fan Speed to UltraHigh by going to the path Service Settings
• Set the selected steps as in point 3.
