OPERATING PANEL USER INSTRUCTIONS
1. Operating panel
The appliance is operated by the means of the operating panel that has four buttons and alphanumeric display with 2x16
indicator lights.
The operation is directed according to settings inserted by the user or installer/manufacturer through the operating panel
as well as according to temperature sensors and set periods.
The operating panel returns from processing state to basic state 30 seconds after the last button pressing. The return time
from normal position is 10 seconds. The background lights of the operating panel will turn off.
Restoring factory settings function on the operating panel -end-users settings will be restored to default factory settings.
Maintenance menu - for setting suitable parameters for the installation. Maintenance menu is hidden from the end-user. -
Restoring factory settings- option is also present in the maintenance menu that can be used for turning all settings (user
settings and maintenance menu) to default settings.
The user can use four different selections on the operating panel: weekday and time, blowing speeds, temperatures and
air quality values in case there are sensors for these functions.
2. Operating card
The operating card manages the unit-s functions according to user-selections and measuring data received from the
sensors. The operating card has additionally two transmitter inputs for %RH or CO
five-speed outputs for two EC air impellers. The operation pane is connected with the operation card by four-polar
modular connector.
3. Controlling of the air impellers
3.1. Speed controlling in default state
Inlet and outlet impellers have 5
the range of 20-100% depending on the working conditions. Impeller speeds are selectable by the user. The speeds are
set to factory defaults in the maintenance menu and the unit starts with factory speeds.
3.2. Overpressurization
Overpressurization state selectable from the outer switch or operation panel. Outlet impeller is set on minimum, inlet
impeller is set to value of the maintenance menu. The intensifications have no impact at this point. The duration of
overpressurization in minutes is selectable by the user. New push from the switch launches overpressurization from the
beginning. Overpressurization can be shut down also from operating panel. Anti-freeze is deactivated when
overpressurization is switched on.
3.3. Intensification
Intensification of air exchange can be activated from the operating panel or stove hood. Activation from the panel sets the
durability of intensification in minutes (5...120min). Maintenance menu is used to set the quantity and default time. In this
case, CO
/%RH intensification has no impact. Intensification is activated also according to external data.

on the operating panel. The air exchange is periodically intensificated by data of %RH - transmitter or transmitters. The
maximum limits of relative humidity are set from the panel by the user (30-80%, 5% steps). %RH measuring values can
be seen on the operating panel. The card has two transmitter inputs that can be chosen separately for CO
activation and deactivation. Regulation interval is a parameter set through the maintenance menu that determines how
often the impeller speed can change in intensification mode. Set value 5-20 minutes by 1 minute. The regulation interval is
same for both CO
- and % RH intensification.

3.5. Out-of-house function
The -out-of-house- function can be selected from the external switch, the impellers are set on minimum speed. However,
previously set intensification or overpressurization will be completed before the impeller speed is reduced or stopped
altogether.
