6.9 Fans control
There could be up to 4 fans in supply and exhaust
according to unit size.
Single fan
In case of single fan, the fan will start according to
sequence and it will regulate according to the
setpoint calculated by the application.
Redundant fans
In case of redundant fans, one fan will be on, while
the other is an emergency fan. Every settable hour,
the fan will switch to keep the same working hours.
Even in case of alarm on the working fan, the SW
will try to switch to the other fan that can work.
The procedure for the redundant fans are:
A delay is provided to allow the damper to open or
close.
Multi Fan
In the multifan regulation, the fans will start at the
same time and they will regulate according to the
same request.
Regulation
The regulation of the fan can be done according to:
1. None
2. CAV regulation
3. VAV regulation
4. Follow supply (for exaust only)
If there isn’t any regulation, the setpoint defined by
scheduler will be actuated by the fans.
In case of VAV regulation, the air pressure is used
as input of the PID and the setpoint is in Pa.
In case of CAV regulation, the air pressure is used
to calculate the air volume in m3/h.
The formula to calcula the air volume is:
AirFlow:=K_Factor*SQRT(AirPress)
Perc – value is changed when is changing work
mode.
K factor is defined by the fan code:

It’s possible in Setpoint loop to change the fan
speed according to unit mode (Eco, Optimal,
Comfort). The value is in percentage of the setpoint
of the fan in service menu.
Selecting the adjustment mode for fan on the
screen Menu ► Unit cfg. ► I03
In the case of CAV regulation (To maintain a
constant output) on the fan configuration screen we
set extreme parameters for a given device:
