7.5. Quick Ventilation Level Switchover
Three ventilation levels are projected in the unit. Each of them has its intensity (more detailed settings see in the
next chapter). There is possibility to switch ventilation level quickly from start-up window (7.3 Picture).
To increase ventilation intensity: touch and hold
by touching
button.
To decrease ventilation intensity: touch and hold
by touching
button.
If ventilation intensity is changed using quick switchover and unit is op-
erating according to weekly schedule, operation mode automatically is
changed to manual mode.
7.6. Unit Programmable Settings
By soft touching
button the parameters menu is entered. Menu window is selected by buttons

Note: If touch sensitive buttons are inactive for 1 minute, start-up window is shown.
1. Unit operation modes setting
Two unit operation modes are possible: manual and automatic. In manual mode unit operates continuously by set
ventilation intensity. In automatic mode unit works according to weekly schedule (see further weekly schedule setting).
Note: If automatic operating mode is selected, there is a symbol
2. Air volume control setting
Supply and exhaust air volumes control modes have been projected in the unit:
•
Constant air volume (CAV) control mode - unit supplies and exhausts constant air volume preset by the user,
independent of the processing changes in the ventilation system;
•
Variable air volume (VAV) control mode - unit supplies and exhausts air volume correspondingly to the ventila-
tion requirements in different premises. In case of frequently changing ventilation demands this air volumes
maintenance mode signally reduces unit exploitation costs.
Menu window for air volume control setting is provided only in the units
having air flow maintenance function. Only with EC fans.
If air handling unit is provided with variable air volume control function,
primary control mode calibration (look further) is essential, otherwise after
choosing VAV mode unit will not operate.
Variable air volume control mode calibration:
1. Before activating the device you should adjust air distribution and exhaust devices in ventilation system, open
all valves for variable air flow in a way enabling air supply to all ventilated premises.
2. Switch on the unit and by choosing menu window for air volume control setting (see above) actuate constant
air volume maintenance mode.
