2.5.2.1. Air quality control
Air quality control is designed according to:
• CO2sensor [0...2000 ppm];
• air quality sensor VOCq [0...100 %];
• air pollution sensor VOCp [0...100 %];
• relative humidity sensor [0...100 %];
Depending on the type of the selected sensor, the value of the air quality
function to be maintained is set, and the air handling unit intensity will be adjusted
according to that value. Ventilation intensity will be increased automatically in the
case of deviation from the set value and decreased again when it is approached.
For example, if the unit is designed with the CO2maintenance function and is
equipped with a CO2sensor, after setting value 800 ppm, this set CO2level will
be maintained by adjusting ventilation intensity, i.e. ventilation intensity will be
increased if the CO2level grows and will be decreased when it returns to the
previous condition.
This function is provided only in units with EC fans.
2.5.2.2. Exhaust air ow correction
Set air ow intensity (or maintained air volume) for 1–99 minutes period can be
corrected from -50 % till +50 % from set value. Example, after reducing exhaust
air ow intensity, for some time overpressure will be caused (sometimes needed
to start the replace or such).
Note: After this function has been activated unit will work for the set time period
with present exhaust correction. After time period is over this function turns off
automatically.
This function is provided only in units with EC fans. This function is not
available in supply air units (OTK).
2.5.2.3. Summer night cooling
If the room temperature (exhaust air) in summertime is 5 °C higher than the set-
point and outside temperature is between 12 °C and the setpoint, the ventilation
level is automatically switched to the third intensity level at 00:15 am. The unit
will operate in the third intensity level until 06:00 am or when outside air cools
down (warms up) too much or the room temperature equals the setpoint. The air
is being cooled only by fans, without heat or coolness recovery and additional air
heating or cooling. When function is switched off the unit continues operating in
the previous mode.
Function starts operating automatically if only the unit operates in the
rst or second operation mode. Function stops operating, when the
mode is being changed.
Summer night cooling and minimum temperature control functions can
not be activated at the same time. When one is selected, another’s
function operation is blocked.

2.5.2.4. Minimum temperature control
In wintertime (outside temperature < 5°C), when heating power is not enough and
supply air temperature is 4°C below setting value, ventilation intensity automati-
cally is decreasing in one level. If there is not enough, one more level (up to mini-
mum) till set supply air temperature will be maintained.
Summer night cooling and minimum temperature control functions can
not be activated at the same time. When one is selected, another’s
function operation is blocked.
2.5.2.5. Override function
Unit is provided with remote control possibility using external device (button, timer,
other sensor) which is connected to the contacts 17, 18 (see chapter 1.3c Picture)
or 27, 28 (see chapter 1.3 d Picture). External signal (short-circuit on contacts 17-
18, 1.3 c Pic. or 27-28, 1.3 d. Pic.) activates “Override” function and air handling
unit starts to operate by the preset parameters.
If “Override” function is deactivated then mentioned contacts can be

2.5.4.1. Air handling unit settings
Temperature control
The air handling unit provides for several temperature control modes:
• Supply. The unit supplies air according to the temperature preset by the user.
• Extract. Unit automatically supplies air of such temperature to maintain preset
exhaust air temperature.
• Auto. When cooling is needed, unit will work in the extract air temperature
maintenance mode. If the outside temperature will be few degrees lower than
set value, control automatically will switch to supply air maintenance mode.
Note. This setting is not intended in supply air units (OTK).
Air volume control
Supply and exhaust air volumes control modes have been provided in the unit:
• CAV – constant air volume control mode. The unit will supply and extract a constant air ow which is preset
by the user, irrespective of any changes occurring in the ventilation system;
• VAV – variable air volume control mode. The unit will supply and extract an air ow with regard to the
ventilation needs in different rooms. In case of frequently changing ventilation demands this air volumes
maintenance mode signally reduces unit exploitation costs.
Menu window for air ow control is intended only in units with EC fans.
It is possible to use a simplied VAV control function, “single-ow VAV control”. It means that the perfor-
mance of this function requires only a single air ow pressure sensor, which is installed in a variable air duct
system (e. g. in supply air). This variable system is called the master ventilation system, according to which
control is performed, while the other air ow (in this case, discharged air) operates as the slave ventilation sys-
tem and always follows the master one. If the supply air requirement in the ventilation system which is assigned
as the master system decreases, the intensity of discharged air in the slave system is reduced correspondingly
by the same percentage.
If the variable air volume control function is mode is selected, the initial
calibration of the control mode must be performed; otherwise, the unit
will not operate if the VAV mode is selected.
Variable air volume control mode calibration:
1. Before start of calibration the air distribution and exhaust devices in ventilation system should be adjusted,
all valves for variable air ow in a way enabling air supply to all ventilated premises should be opened.
2. After switch on of the unit the VAV mode should be selected and calibration procedure should be conrmed.
After the end of the calibration, depending on the conguration of pressure sensors, VAV mode status will
change to Supply, Extract, Double.
3. After calibration the air handling unit further will operate in the previous mode.
Time / Date
Time and date is required for air handling unit operation planning.
Season
For the air handling unit operating in most economical mode, summer and winter seasons have been provided.
• By setting “Winter” season, unit cooling function is blocked.
• By setting “Summer” season, unit heating function is blocked.
• By setting “Auto”, automatic season selection will take place. Depending on
the heating and cooling demand, the season is selected automatically.

2.6. Other Control Functions
2.6.1. Remote unit switching on or off
If the unit is not operating according to programmed week schedule, by connecting (short-circuit) contacts 17,
18 (see chapter 1.3 c Picture) or 27, 28 (see chapter 1.3 d Picture) unit will be switched on and will operate in
mode, which is set in the panel main window (see Chapter 2.4); by disconnecting contacts unit operation will
return to standby mode.
If unit is operating in auto mode with chosen intensity, to switch it off by remote switch contacts 17, 18 (see
chapter 1.3 c Picture) or 27, 28 (see chapter 1.3 d Picture) must be connected (short-circuit).
Remote unit switching on and off is available only after activation of the
weekly program (Chapter 2.5.3.) and deactivation of “Override” function
(Chapter 2.5.2.5.)
2.6.2. Pump control
Units with water heater are designed with water circulation pump control. In winter pump operates continually,
in summer season it is off. When outdoor temperature is lower than 5 °C, pump is automatically turned on.
Pump is connected to the connection box contacts (see 1.3. chapter).
2.6.3. Cooling energy recovery
In summer when room temperature is lower than temperature outside, units with either plate heat exchanger or
rotary heat exchanger automatically operate with activated function of cooling energy recovery. This function
is not intended in supply air units (OTK).
2.6.4. Remote unit operation and failure indication
If the information about unit operation mode is requested (when unit is operating and when is not) indication
device (for ex. bulb) must be connected to the contacts 33, 35 (see chapter 1.3 c Picture). In the connection
board (see chapter 1.3.) are provided contacts 33, 34 (see chapter 1.3 c Picture) or 29, 30 (see chapter 1.3 d
Picture), which are intended for connection of unit’s emergency stop indicating device.
2.7. Unit PC control
This is additionally ordered function and for it implementation special network module “Ping2” is provided.
Connection diagrams and installation requirements of network module are given in the “Ping2” module instal-
lation manual.
After connecting units through special network modules to computer network or Internet and given an IP
address, integrated web server allows the operator from his computer not only to monitor, but also to control
air handling units operation: to turn on/off, change ventilation intensity and etc. It also allows indicating failures.
2.8. Troubleshooting
If the unit is not working:
• Make sure if the unit is connected to the electrical power supply.
• Check if the unit main switch is on (if designed).
• Check all control block fuses. If needed, change failed fuses with the new ones that are the same electrical
parameters as old ones (fuses types are shown in wiring diagrams).
• Check if there is not failure indication on the control panel. If there is indication, it needs to be eliminated
rst. To eliminate failure use 2.8 Table, which describes failures.
• If nothing is indicating on control panel, check whether cable connecting control panel with the unit is not
damaged.
