UNIT CONTROL
Fig. 5. Control Panel
The unit control panel is designed to run two alternative software versions:
•
DUO/6M901580B (installed by default);
•
DUO/6Т901580.
The software version installed on a specifi c unit is specifi ed on the label attached to the rear side of
the control panel.
The unit is operated via the control panel (Fig. 5).
1. Ventilation mode control.
The air-handling unit has three ventilation modes:
MIN - the basic ventilation mode. The air fl ow rate for this mode is selected in the Setup
mode according to Table 3 (see p.2 Setup Mode);
NORMAL - the air fl ow rate in this mode is 80 m³/h higher than in the MIN mode.
The DUO/6Т901580 software automatically reverts the unit to the MIN mode 30 minutes after
enabling the NORMAL mode;
MAX - delivers the maximum air fl ow rate according to the unit specifi cations.
The ventilation modes indication is explained in Table 2.
To switch between ventilation modes use the
button.
