VISUALIZATION MAIN SCREEN

The touch screen control panel has been designed to manage units of Mechanically Controlled Ventilation with Heat Recovery (VMC-RC) in
a simple and intuitive way. The user manages the control by means of the icons of the graphic screen making a slight pressure on them; The
direction buttons, which appear after the pressure in a modifiable parameter, allow the user to interact with the unit by going through menu
items and modifying values. Pressing the OK button confirms the modifications or selections made. The color change (green) of an icon after
a press indicates that the parameter represented by that icon can be changed. When an element of the submenus is highlighted, it appears in
background color on a blue background, pressing OK the title changes to green and modifications can be made with the direction buttons.

The main window is a detailed graphic representation of the state of the machine from which all available functions can be activated. To chan­ge the window and access the other menus, you have to press the icon to change the menu window. From the other windows you can return
to the previous one by selecting the mentioned icon and pressing OK. To save energy the control is placed in standby mode (paid screen) after
a minute of inactivity, pressing at any point on the screen is automatically reactivated. In the presence of alarms, on the other hand, the screen
lights up for half a second approximately every ten.

MANAGEMENT OF FAN SPEED, FLOW OR CONSTANT PRESSURE

To modify this parameter, the icon at the top right of the synoptic table must be selected by clicking on it (it will turn green and the direction
buttons will appear). Then press the icon of the address button up to increase or down direction to decrease the value located next to it; Once
the desired one is located, press the OK button to confirm the selection. At first it is possible to turn off the machine directly by pressing the
central button, it disappears automatically by pressing the direction buttons. The variation can be expressed as a percentage for variable spe­ed machines, with a simple 1-2-3 for machines with 3 speeds, in flow (m³ \ h) for machines with constant flow or pressure (Pa) for machines with
constant expression (equipped with the corresponding supplementary kit, see page 29). For these last two models, once the desired value has
been selected, the speed of the fans will automatically vary to keep the flow or the set pressure constant. For machines with a sensor mounted
different from the cop / cav kit, but always with constant pressure or flow rate, enter the percentage value of the pressure or flow scale of the
unit. The regulation it will be carried out in the same way. This also applies to the settings of the weekly programming menu (Program). In
addition to the scale value, the timer element will appear and, if selected, will start the default weekly time program (see Program menu). If an
air quality, relative humidity sensor is present in the unit or if the analog input (0-10V) is activated, we will also have the automatic selection
that allows the automatic regulation of the fan speed in function of CO2, Humidity measured or by an external signal.

In detail the possible selections are:

- off: with this selection, the fans are stopped. Be careful because in any case the unit is electrically powered; this value is obtained by descen­ding below the minimum adjustable speed.

-xxx%: if the unit has modulating fans it is possible to adjust a percentage value of the speed, flow rate or full-scale pressure (for units not
equipped with the corresponding kit but always in a cop / cav version with a different sensor), starting from a minimum (factory adjusted) to
100% with steps of 5% (1% on request).

-1, 2 or 3: if the unit is equipped with 3-speed fans, it is possible to select one of the available ones: speed 1, speed 2 or speed 3.

-watch: with this selection the speed of the fans is controlled according to what is established by the weekly chronoprogram (see Program

menu), this indication is obtained by selecting a value higher than the maximum speed (100% or 3).

- auto: this mode is available only if a sensor (CO2, CO2-COV, relative humidity HR) or an external signal (0-10V) is present. It is obtained by
selecting a value higher than clock.

- xxx m³ \ h: if the unit is a constant flow (CAV) version with a kit, the desired value can be set in m3 \ h of flow. The fans will be regulated au­tomatically to keep it constant depending on the changes in the load.

BOOSTER FUNCTION

By selecting the icon on the lower left you access the booster function. Through this you can select a time interval (from a minimum of 1 mi­nute to a maximum of 4 hours) in which to operate the unit at maximum power. The booster function is a priority with respect to other modes
of fan speed management.
After the selection a digital chronometer (hours.minutos.seconds) predetermined to a value of 10 minutes can be modified with the direction
buttons on the right of the screen: up to increase the booster time and down to decrease this time. Pressing the OK button starts the function:
the remaining time for the end of the process is shown on the screen.
When the value 00.00.00 is reached, the fans are controlled again in the previous way. If it is desired to stop the process, it is sufficient to repeat
the adjustment operations of the booster by selecting a time of 0 minutes and pressing OK.

MANAGEMENT OF AIR POSTGRADING

The control is capable of managing an air after-treatment system with both water coil and electrical resistance.
The first is regulated by the control of a 3-point solenoid valve 230V or 24AC-DC \ 0-10V, while the resistance through the corresponding relay.
If after-treatment management is established, the main screen is modified: an icon - thermometer with a temperature value appears in the
lower right corner. On its side and on the flow of the driving air, a picture of post-heating / cooling appears.

Selecting the icon in the bottom right corner establishes the desired temperature set point (TS) inside: the user can increase the value of TS
with the direction arrow up or, on the contrary, decrease it with the Direction arrow below. Once the desired value has been reached, the se­lection is confirmed by pressing the OK button. With the central button, which appears at first, the post-treatment can be switched off directly.
TS can assume values between 05.0 ° C and 30.0 ° C with steps of 0.1 ° C; if the user selects a TS value lower than 05.0 ° C, the control considers
the post-heating deactivated and the display appears next to the corresponding icon on the screen. It is possible to combine electric after­heating for winter and water cooling in summer, or under the same conditions, control two separate cold-hot coil (cold only with 0-10V valve).
TS becomes the reference for heating or cooling depending on whether or not these are enabled in the corresponding station of the installer
menu (exclusive to each other) and depending on the one selected in the parameter menu. The post-heating status is shown in the main
window: It is also possible to manage a dehumidification system made by the two separate coil (hot-cold) or by a cold coils with an electrical
resistance underneath.

PREHEATING MANAGEMENT

In addition to the post-heating, the CTRL-MAX2 control is able to manage an electric preheating system (operated by a PWM signal or on-off)
to prevent the formation of ice inside the heat exchanger. The control automatically activates the anti-frost procedure when the temperature
measured by the expulsion probe (Tx) drops below the value of 3 °C. Here the heater is powered at the minimum power. If the temperature Tx
continues to decrease and falls below 1 °C, the feed of the preheater is progressively increased until it reaches 100%. When Tx returns above
3 °C the procedure is interrupted. The temperature values 3C° and 1C° are set at the factory and can be modified on request. The preheating
status is shown in the main window.

MENU SELECTION

From the main window you access the menu window by touching the corresponding icon (window change icon). You have to scroll with the
up arrow key and then press OK on the desired item. When selecting, you access the diverse detailed information about the installation. When
the last menu item is reached, the arrow below disappears.
On the other hand, when you go beyond the first one, the window change icon appears with the arrow to the left. To return to the previous
menu, click on the latter.

In the menu window you can access the following functions:

- Status

resistance management, it stops both the impulsion fan and the resistance, the
return flow goes to the speed set in the control panel. For by-pass manage­ment, it stops the flow fan and leaves the by-pass in the current position.

Bypass off:

The bypass will remain closed regardless of the internal and external temperatures.

Bypass on:

The bypass will remain open regardless of the internal and external temperatures.

PARAM MENU: ADJUSTMENT OF USER PARAMETERS

The parameter menu is displayed only when the control detects that the conditions exist for which the current station should be selected. It
may be due to the winter / summer settings in the installer menu (see) or the presence of a cold water coil. If it is not displayed, the control
automatically proceeds to the management based on the outside temperature and return values. Modification of the values of the available
parameters is done by selecting the desired one and pressing the OK key; at this point the current value of the parameter turns green, to go
through the different possible values, use the arrows. If a dehumidification system is installed, the relative humidity threshold value can also
be adjusted in this menu.

Bypass configured in “All Season \ All SeasonM” mode and / or management of an element enabled for air after-treatment (Factory menu). For
the regulation, threshold values of the return temperature present in the installer menu are used (see Winter / Summer temperature) which
are compared with the effective values of outdoor temperature \ ambient. If the conditions for free-heating/ cooling persist, the by-pass is
adjusted accordingly according to the following diagram:

Humidity (%)

This parameter is available only when a dehumidification system is planned. Represents the threshold value above which dehumidification is
enabled. The default value is 50%. Dehumidification can also be forced by a digital input.

INSTALLER MENU: CONFIGURATION OF INSTALLATION PARAMETERS

To access this menu, you need to enter a password (5678) to avoid inadvertent modification by non-expert users of parameters that could
compromise the correct operation of the installation.

To enter the password, press the down arrow so that the corresponding line is indicated, press the OK button and enter the first digit. Select
the desired value using the up / down arrows and press OK when you reach it.
Repeat the operation for the three remaining figures. If the password has been entered correctly, the installer menu is displayed; otherwise,
you return to the introduction page. To modify the parameters of this menu, select the desired one (scrolling with the up/ down arrows) and
press the OK button. The currently established value is shown in green, at this point it is possible to modify it using the arrows and pressing
OK to confirm the selection. The parameters related to the coefficients and flow/ pressure values are available only for machines with kit, the
display or not of such parameters is linked to the settings in the factory menu.

Bypass configured in universal mode (Factory menu), three values can be selected for the bypass parameter:
Automatic bypass:
A temperature range, comprised between TMIN and TMAX, is considered comfortable for the user; If the internal temperature (Tr) is within this
range, the bypass will remain closed. When Tr is out of this range (Tr> TMAX or Tr <TMIN) the control will open the bypass in case the external
temperature (Te) is within the comfort range (TMIN <Te <TMAX); otherwise, the bypass will remain closed.

Not defined or automatic

This parameter is available only when a dehumidification system is planned.

Through this you can enable (Yes) or inhibit (No) the dehumidification

system. It can be used, for example, in the winter season, if you do not want

to dehumidify.

Auto

With this parameter you can configure a device to regulate the fan speed automatically. For the connection of the device see the electrical
diagram.
ex signal The speed of the fans will be regulated by an external 0-10V analog signal (default value); if the external signal assumes a value equal
to 0V; the control will signal a problem of the external signal source. For units equipped with variable speed fans:

AutoMin% corresponds to the percentage of the input signal by which the fans must operate at the minimum speed.
AutoMax% corresponds to the percentage of the input signal by which the fans must operate at maximum speed.

For units equipped with three-speed fans:

SP. 1,2% = Automax% - AutoMin%+ AutoMin%

SP. 2,3% = 7 x (AutoMax% - AutoMin%) + AutoMin%

∆ = Automax% - AutoMin%

CV072018-1

HR Sensor

The speed of the fans will be regulated by a relative humidity (RH) sensor with 0-10V output and linear characteristic between 0 and 100% RH
(0V correspond to 0% RH and 10V correspond to 100% RH); If the external signal from the HR sensor assumes a value equal to 0V, the control
will signal an alarm. See graphs of the signal parameter ext. In this case AutoMin% corresponds to the relative humidity value for which it is
considered optimal air quality, AutoMax% corresponds to the value of relative humidity for which the air quality is considered bad. A possible
dehumidification system can be managed by this sensor or, if for example this input is occupied by CO2, by another supplementary selected
in the factory menu.

CO

2

VOC

The speed of the fans will be regulated by a CO2 sensor (or CO2-VOC) with 0-10V output and linear characteristic between 0 and 2000 ppm
(0V correspond to 0 ppm and 10V correspond to 2000 ppm); if the external signal of the CO2 sensor takes a value equal to 0V the control will
signal an alarm. For units equipped with variable speed fans:

AutoMin ppm corresponds to the concentration of CO2 (CO2-VOC) for which air quality is considered optimal, AutoMax ppm corresponds to
the concentration of CO2 (CO2-VOC) for which air quality is considered poor.

For units equipped with three-speed fans:

SP. 1,2% = Automax ppm - AutoMin ppm + AutoMin ppm

SP. 2,3% = 7 x (AutoMax ppm - AutoMin ppm) + AutoMin ppm

∆ = Automax ppm - AutoMin ppm

adjusted to the maximum speed. For example, the AutoMax value% 080 corresponds to an 8V input signal (80% of 10V).

If auto sensor HR

corresponds to the relative humidity value (in percentage) by which the fans rotate at the maximum speed, below this value the fans remain
adjusted to the maximum speed. For units equipped with three-speed fans, taking into account the second image of the external auto-signal
parameter, the values of SP.1.2% and SP.2.3% are set (nominal values in which the steps of the speed 1 to 2 and speed 2 to 3) you can obtain
the appropriate value to assign to the parameter:

AutoMin ppm

This parameter is available only if the auto parameter is set to CO2 VOC. It can take values between 0 ppm and 1980 ppm (steps of 20ppm) with
the limitation that AutoMin ppm <AutoMax ppm.

the minimum speed; below this value the fans remain adjusted to the minimum speed. For units equipped with three-speed fans, taking into
account the second image of the auto CO2 VOC parameter, the values of SP.1.2% and SP.2.3% are set (nominal values in which the speed steps
are produced) 1 to 2 and speed 2 to 3) you can obtain the appropriate value to assign to the parameter:

AutoMax ppm

This parameter is available only if the auto parameter is set to CO2 VOC. It can take values between 20 ppm and 2000 ppm (steps of 20 ppm)
with the limitation that AutoMin ppm <AutoMax ppm For unit equipped with variable speed fans, corresponds to the concentration of CO

and SP.2.3% are set (nominal values in which the speed steps occur 1 to 2 and speed 2 to 3) you can obtain the appropriate value to assign to
the parameter:

AutoMin% = 7 x SP.1,2% - 2 x SP.2,3%

AutoMax% = 8 x SP.2,3% - 3 x SP.1,2%

5

AutoMin ppm = 7 x SP.1,2% - 2 x SP. 2,3%

AutoMin %
This parameter is available only if the auto parameter is set to ext. or HR sensor. It can take values between 0 and 99% (steps 1%) with the
limitation that AutoMin% <AutoMax% For units equipped with variable speed fans:

If auto signal ext.

corresponds to the percentage value of the input signal by which the fans rotate at the minimum speed, below this value the fans remain
adjusted to the minimum speed. For example, the AutoMin% 030 value corresponds to a 3V input signal (30% of 10V).

If auto sensor HR

corresponds to the relative humidity value (in percentage) by which the fans rotate at the minimum speed, below this value the fans remain
adjusted to the minimum speed. For units equipped with three-speed fans, taking into account the second image of the external auto-signal

WINTER TEMPERATURE / SUMMER TEMPERATURE

Through these parameters you can access the menus below to adjust the effective return temperature threshold values (Tr) for bypass or
base management for bypass management with air after-treatment. The summer / winter values coincide in order to have an optimal setting
for all seasons. In this way, if the post-cooling is not installed, the transition operation is also avoided by inhibiting the parameter menu (it is

Web server

Installed directly on the touch panel we have a web server that allows us to monitor the status of the machine and modify its parameters
through PC. Modifications made with web services are permanent and remain stored even if the unit is turned off. For the connection to the
web server to be correct, the first three fields of the IP address of the panel and that of the computer to which it is connected must match. For
example, if our address is 192.168.1.243, the address of the PC should be 192.168.1.xxx. To start the web server after connecting the network
machine, open your browser and type in the address bar: http \\ 192.168.1.243.
The main screen will appear as in the figure:

On the screen we find a reproduction of the typical touch panel screen, the differences are the variations that are made with the arrow but­tons. You can increase or decrease the values of a unit by clicking on the button of an arrow; with the button of two arrows it can be increased
or decreased in several units. By means of the central button you can carry out the direct shutdown of the after-heating, fans and timer. The
modifications made are saved automatically after 5 seconds. The writing of the retention records via Modbus is disabled for 60 sec after each
modification made with the web server. To have a continuous update of the website, click on the “refresh on” button, it will go to “refresh
off” and the page will be updated every 5 sec. If the machine is equipped with a post-heating system we will also have the desired set point
