Working Modes - Swegon TAC5F Manuel D'installation

3 REGULATION: CONFIGURATION – WIRING – OPERATING

3.1 Working Modes

Slots IN1 and +12V have been prewiring to allow the control of the unit via inputs/outputs on TAC5 F.
The various working modes give the user the choice on how the airflow must be modulated according to
your application.
All working modes allow defining how the airflow or the fan torque must be modulated according to the
application. The airflow shall be modulated by default unless for backward fans without pressure sensor
at inlet or, for all the other cases, when the "TQ" mode has been selected in the advanced setup, then it
will be the fan torque that shall be modulated.
In case of presence of 2 fans, the airflow/torque of the second one shall be configured either as dependent
of the first one with the definition of a ratio between the 2 airflows/torques, or independent with a
separated definition for the 2 airflows/torques.
3.1.1 Configuration
The setup is made by means of the LCD screen and the 4 knobs SETUP, ↑, ↓ and ENTER of the TAC5
F.
To start the setup, press the SETUP knob until the text "SETUP" appears on the
screen).
The idea is to select your choice with the ↑↓ knobs and then to confirm your
choice by pressing 'ENTER'. The numbers are introduced digit by digit
The displayed menus will be different in function of the selected working mode, fan type and fan
quantity.
In any case, for menu item « TYPE FAN», it will be possible to select, as well as for forward and
backward fans, the specific fan identified with its code ID (CID) written on the fan label.
3.1.2 Working Modes with Airflow Modulation
3.1.2.1 CA Mode
3 constant airflow set points are determined by the user (m³h K1, m³h K2 and m³h K3).

Choose the language (English, French, Dutch, German)
If yes, the airflow of the fan will be displayed.
If yes, the pressure of the fan will be displayed (not available for fans 720999 and
720998)
If yes, the speed of the air of the fan flow will be displayed
If DISPLAY Pa = yes, enter the area of the blowing duct.
Choice of the fan type (CID – see label on fan or
fan with speed feedback or 720998 for generic backward fan with run
contact
).
Select number of fans connected to CB (F1 or F1+F2).
If # FAN=F1 + F2. Choose yes in case of dependent fans: the airflow of fan 2 is
defined as the airflow of fan 1 per a ratio defined in menu item %F2/F1. Choose no
in case of independent fans: the 2 fans have their own setpoints.
Choice of the working mode (CA, LS, CPf, CPs). Select CA
