2.5. 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 (2.3 Picture).
To increase ventilation intensity:
touch and hold
and at the same moment increase ventilation in-
tensity by touching button.
To decrease ventilation intensity:
touch and hold
and at same moment decrease ventilation intensity
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.
2.6. Unit Programmable Settings
By soft touching
button the parameters menu is entered. Menu window is selected by buttons , (see
further description). When menu window is selected, touch
for selecting desirable parameters and select
the value with ,
. To confirm the changes touch
.
To return to previous menu or to start-up window touch button.
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
in the start-up window.
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
ventilation 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.
