9.5 Fan Speed Adjustment
The installer is responsible for setting the required air volume rates for every room in compliance
with the Domestic Ventilation Compliance Guide 2010.
The Duplexvent BV400 unit has a 3-speed control switch which is supplied as standard. The low
and high speed levels can be adjusted by manual potentiometers for commissioning purposes.
This can be done through the control box which is located inside the unit. The medium speed has
been set in the controller's software by the manufacturer and is set as the average value of the
manually adjusted low and high speed levels.

Note : The low and high speed levels can be adjusted for commissioning purposes by changing
values in Registers 68-71 in Pro Panel (please see chapter 9.4.4).
This can be also done by using manual potentiometers, which are located at the control box
mounted on the Fan module inside the unit. The medium speed has been set in the controller's
software by the manufacturer and is set as the average value of the manually adjusted low and
high speed levels.
9.6 Other Control Functions
Boost Function
This function is used when large amounts of exhaust and fresh air are required.
There are 2 different boost functions (Manual and On-demand):
a) “Boost” function is activated by pressing on Pro Panel for 3 seconds. After unit
runs at boost speed (maximum speed) and during boost time (15 minutes) , it begins
to run at the speed value that is set before boost function is activated.
b) There is one dry contact relay input and one 230V input on control board. If one of
these inputs is activated, unit begins to run at “boost” speed. When activated input is
passive again, unit begins to run at the speed value that is set before boost function is
activated.
Note : Boost speed and boost time are changeable on Pro Panel.
