2.4. 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 inten
-
sity 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

schedule setting).
Note:
If automatic operating mode is selected, there is a symbol

.
2. Setting ventilation level
Ventilation equipment has three levels of ventilation. Fan intensity for every of the free levels can be attributed
separately for the supplied and exhausted air from 20 % to 100 %, in 1 % steps.
Intensity potentiometers on the automation box inside the air handling
unit are not used, their settings have no effect for the unit control when a
control panel with touch-sensitive buttons is connected.
3. Activation of the OVR function
Air handling units have the OVR function, which detailed description can be found in chapter 2.6. The OVR func
-
tion can be activated in two ways:
1. By the external control device.
Connection is described in chapter 1.4. After interconnecting (short-
circuiting) the FC contacts (see the electrical diagram), the unit will operate in the selected OVR mode and
after disconnection it will return to the previous operation mode.
2. By control panel.
In this case there is no need for additional connections to external control devices, the
function is activated from the panel, and the unit will operate in the chosen OVR mode until the internal timer
is active (from 1 to 90 minutes):
