1. Installation require ents
Room conditions, where control panel is installed, must ensure en ironmental requirements:
•ambient temperature: 0 °C ... 40 °C
•relati e humidity range: 20 % ... 80 %, non-condensing
•protection against ertical dripping water
•no excessi e ibrations
The control panel can be mounted
on a flush mounting box or in any other place screwing two-
four holes on the fastening surface. Alternati e mounting option is attaching control panel to
magnetic surface (for example air handling unit metallic case) without screwing using integrated
magnets on the back of the panel.
Control panel cable connection is pro ided through a hole in the back or bottom side, depending
on installation requirements. The length of the cable for connecting the panel with the controller
may not exceed 150 m.
Panel mounting diagram showed below. Connection cable is within flush mounting box circle.
Screws used for control panel mounting on a flush mounting box or surface
must be 2,0..3,0mm diameter and be flat head type. Failure to obser e this
requirement can cause permanent control panel failure that is not co ered by
warranty.
It is recommended to lay control panel cable separately from power cables in a
distance no less than 20 cm.

4. Operating functions
4.1. Unit control
Control system ensures control of the physical processes that are taking
place inside the air handling unit.
Control system consists of:
• controller module;
• temperature sensors and control panel, which can be installed in the
con enient place for the user.
4.2. Control panel indication
Explanation of the displayed symbols:

4.3. Operation odes selection
Three operation modes are possible, one of them user can directly select from control panel
main window:
•Away;
•Home;
•Boost.
The mode is selected by tapping one of modes buttons located in the main window. The
corresponding button becomes black, when the selected mode is acti ated. The user can set
entilation intensity separately for supply and extract air in each operation mode. Ventilation
intensity mode window is opened by pressing and holding one of modes buttons. The supply air
temperature is set by tapping round button in the center of main window.
4.4. Menu
Menu of panel consists of the fi e points:
•O er iew;
•Scheduling;
•Functions;
•Settings;
•On/Off.
4.4.1. Overview
All information, relating to the operation and alarms of the unit, is detailed
in o er iew menu.
SIMNA, Ozo st 10, LT-08200 Vilnius, Lithuania. info@simna.lt www.simna.lt
4.4.1.1. Alar s
This menu displays the notification of existing faults. After failure
elimination (see chapter 5), messages are deleted by selecting “Delete”. By
clicking on „History“ can be iewed up to 50 registered alarms.
4.4.1.2. Detailed infor ation
All temperature sensor readings, functioning of separate air handling unit
elements and other detailed information is a ailable in this menu.
4.4.2. Scheduling
Menu for planning of the air handling unit operation
according to the weekly program.
Three e ents can be set up for e ery week day. One
of three modes can be assigned to each e ent. E ery
e ent has a timing, when the selected mode should
be acti e. The timing is set by tapping “Start” and
“Stop”. When the mode “Standby” is selected, the
fans are stopped and the unit is inacti e until the
next e ent.
Exa ple:
Monday:
07:30 – 11:00 Away mode is acti e
11:30 – 16:00 Home mode is acti e
16:00 – 17:00 Boost mode is acti e
The rest of the day the unit operates in Standby mode.
E ery e ent start and end time is set from 0:00 to 24:00 h. The e ents should be set consistently
from the first one at the top of the window.

4.4.3. Functions
In this menu item, the user can acti ate and set additional unit functions:
•Setpoint sliding;
•O erride function.
blank box: function is not acti ated
grey box: function is acti ated
4.4.3.1. Setpoint sliding
The temperature setting point can be shifted from -9 °C to +9 °C from the
temperature set alue at user-specified time period. E ent start and end
time is set from 0:00 to 24:00 h.
When setpoint sliding is acti e according to set time period, the setpoint
sliding icon will be displayed in the main window (see chapter 4.2).
4.4.3.2. Override function
O erride function is intended for remote air handling unit control by an
additional external de ice. After the acti ation of this function the current
mode of operation will be ignored and the unit will operate at set
intensities. Intensities can be set from 20 to 100 % inter al.
The function can be acti ated in two ways:
•By the external control device - Interconnecting (short-circuiting)
the controller’s O erride function contacts. Unit will operate in the
selected O erride mode and after disconnection it will return to the
pre ious operation mode. Acti ation by external de ice has the highest priority and will
force the unit to start e en from stopped mode.
•By control panel or Modbus protocol – in this case there is no need for additional
connections to external control de ices, the function is acti ated from the control panel
or Modbus protocol, and the unit will operate in the chosen
O erride mode until the internal timer is acti e (user-defined from 1
to 90 minutes). When this function is acti e, the intensities of the
supplied air and separately for the extracted air fans can be
adjusted ia control panel or any time ia Modbus registers.
When O erride function is acti ated, the mode selection
buttons in the main window are inacti e. The corresponding
icon appears in notification bar (see chapter 4.2).
SIMNA, Ozo st 10, LT-08200 Vilnius, Lithuania. info@simna.lt www.simna.lt
Typical applications of the O erride function:
•Maintenance of CO
2
quantity or VOC air quality in roo – by adding an additional CO
2
or
VOC sensor (with relay output), the main user-set entilation rate at lower air quality will
be switched to the maximum or other preset intensity until the room is entilated, then
unit will return to the pre iously mode.
•Maintenance of relative hu idity in the roo – after contacting the external relati e
humidity sensor (with output relay), automatically switching to maximum or other preset
entilation intensity will maintain the humidity le el, desired by the user.
•Ventilation on de and – when the motion sensor is connected to the control contacts,
entilation will be adjusted according to demand, i.e. if people are indoors, entilation will
be carried out according to the set O erride intensity and if there is nobody in the room –
the unit will operate according to main user-set intensity, for example, the minimum.
•Ventilation with additional air extraction – connection of additional extracting de ice, for
example, a kitchen hood or other extraction de ice without a separate fan, is intended,
thus the air extraction is carried out by the unit itself. After the acti ation of the function
the supply and extract air fans start operating at maximum or other preset intensity.
•Negative pressure co pensation – intended for systems where air extraction can be
carried out in a separate air extraction fan. Supply fan then should be preset to higher
intensity than extract fan and after acti ation of the function, negati e pressure in the
room compensation can be achie ed.
4.4.4. Settings
This menu is for air handling unit and the user parameters setting. The user
can switch the menu languages, change the screen sa er, panel lock, touch
sound, season, time and date.
For the air handling unit operating in most economical mode, summer and
winter seasons ha e been pro ided:
•Su er - heater operation is blocked but allowed cooler operation;
•Winter - cooler operation is una ailable but allowed heater
operation.
Time and date is required for air handling unit operation planning.
4.4.5. Unit switching on or off
This menu item is intended for the air handling unit switching on/off.
After switching the unit off, it will not operate according to
weekly program.
