1. Operating panel
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 2 minutes after the last button pressing. The return time
from normal position is 2 minutes.
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 to
default settings.
The user can use four different selections on the operating panel: weekday and time with the shortcut icons, blowing
speeds, temperatures and air quality values in case there are sensors for these functions.
2. Operating card
The controller card controls the operation of the device user's choices and measurement data from the sensors Received
by. The controller card is
in addition to two transmitter inputs Which can be connected% RH or CO
2
transmitter. The card has an additional 4 pcs
switch data inputs and two
EC - a five-speed fan outputs. The control panel is connected to the controller card, a modular six-pole.
3. Controlling of the air impellers
3.1. Speed controlling in default state
The supply and exhaust air controlled 5 speed. Maintenance menu can be selected fans (20-100%) are suitable for
speeds of the subject. The fan speeds are individually user selectable. At speeds in the service menu is the default
setting which the machine starts.
3.2. Overpressurization
Overpressurization state selectable from the outer switch or operation panel. Outlet impeller runs at basic speed, 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, CO2/%RH intensification has no impact. Intensification is activated also according to external data.
3.4. CO
2
- and %RH- intensification
CO
2
– transmitter or data given by the transmitter is the basis for air exchange intensification in regulating intervals.
The CO2 maximum limits are set from the panel by the user (250…1500ppm, 50ppm steps). CO
2
measuring values can
be seen 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%, 1% steps). %RH
measuring values can be seen on the operating panel. The card has two transmitter inputs that can be chosen separately
for CO
2
or %RH 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
2
- and % RH intensification.
3.5. Out-of-house function
The “out-of-house” function can be selected from the external switch or from the operating panel. 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.
3.6. Weekly clock
The program selectable by the user enables to reduce/increase air exchange during selected periods of time. 5 different
time periods can be programmed at the same time. Each time period can be set with one or several weekdays.
