GENERAL CHARACTERISTICS
The EVOLUTION controller allows independent control of all the unit
operating parameters.
The controller is made up of:
• A microprocessor control board housed inside the electrical panel
• A user terminal or graphic interface
The program that resides on the control board can be used on all types
of precision air-conditioning units, specifically:
• direct expansion units, water cooled or air cooled;
• water chiller units;
• direct expansion units with energy saving function;
• dual cooling units.
The main functions of the program are:
• management of the temperature and humidity in civil or technological
environments;
• management of 1 or 2 scroll compressors
• management of between 1 and 3 electric heating stages for heating
and post-heating;
• management of modulating valves for cooling using cold water and
heating using hot water;
• management of the evaporator fan speed, when featured;
• management of an external or built-in immersed electrode humidifi-
er;
• outlet temperature control;
• management of alarms and maintenance warnings;
• logging of up to 100 alarm events;
• management of the safety running time for each components;
• unit on/off from user terminal, remote contact, supervisory system
and according to time bands;
• local network (LAN) connection for managing backup units;
• connection to local supervision networks and BMS (LonWorks,
BACnet, Modbus…..).
Throught the user terminal you can view and modify (by using a pas-
saword) all following datas:
• values read by the probes and the corresponding calibration;
• active alarms, alarm log, configuration of the alarm digital outputs;
• configuration of the local network (LAN);
• parameter settings for serial communication with the supervisory
system;
• configuration parameters and fundamental control parameters;
• operating hours and number of starts of the controlled devices;
• clock settings;
• selection between the different languages available.
Using the local network connection, the program can manage the fol-
lowing additional functions:
• Automatic rotation by time or event, for 1 or 2 units in stand by
mode, between max 10 units connected in LAN
• management of the average temperature and humidity readings from
a maximum of 10 units;
• use of just one terminal to control a maximum of 10 units;
In order to protect the program default settings, the software features
two levels of password, USER for the main user settings, and FACTORY
for the authorised technicians, used to modify and reset all the software
parameters.
The user interface is made up of:
• 11x15 pixel backlit LCD;
• 6 backlit buttons for scrolling and modifying the parameters.
The microprocessor board is connected to the user interface
using a 4-pin telephone cable with RJ11 jack.

EVENT OF ALARM
In case of Alarm event:
• Acoustic signalling is activated (buzzer);
• Red led under the alarm button s activated;
• Green leds on main screen are activated
• AREA 2 on main screen is showing the alarm icon;
• AREA 3 on main screen visualized an icon who represent the
kind of active alarm .
With a single press on the alarm button the acoustic signalling is
de-activated.
RESET OF ALARM STATUS
To make the ALARM RESET, we split the alarms in 3 different
kind:
• Alarms with only Automatic Reset:
in this category we found only the alarm “LAN DISCONNEC-
TED”.
• Alarms with Automatic/Manual Reset (based on the customer's
settings on screen I3); in this category we found:
- Ambient Temperature Limits overcoming
- Ambient Humidity Limits overcoming
- Chilled Water too high
- Water Flow missing
- Low Pressure alarm
- Humidifier alarm
- Air filter alarm
By default alla bove are setted with AUTOMATIC RESET.
• Alarms with only Manual Reset:
After removing the alarm cause, it's required to push alarm but-
ton for few seconds to remove completely the alarm signalling
and will desappear any Alarm icon from AREA 2 and AREA 3.
With “Wrong Password Alarm”, the RESET is only manual after
the right input of the correct password.
ALARM LIMITS
With User Password (screens “I”): it's possibile to modify the
alarms limits setted like,Ambient Temperature Limits overcoming,
Ambient Humidity Limits overcoming, Chilled water too high( 2
limits: 1 for standard functiuoning, 2 for dehumidification functio-
ning) anyway based on unit configuration.
ALARMS OUTPUTS
With User Password (screens “I”): it is possible to configure the
alarms output available on the main board. Based on unit configu-
ration we can have 1 Alarm output (marked A) or 2 Alarm out-
puts (marked A & B).
We can also set:
• Status of Alarm Contacts (normally Open or Closed in OFF
position: in this second case we can also raise the “power mis-
sing alarm”);
• Address the desire alarm in contact A or B , depending on
customer choice.

GENERAL INFORMATION AND DEFINITIONS AIU
1The local network connection is used to manage the operation
of a series of air-conditioners operating inside the same envi-
ronment, or a series of liquid chillers connected in parallel in
the same installation.
2The max number of units that can be connected is 10.
3The maximum extension of the network connections is 500
metres.
4All the units connected in the network must have the same ver-
sion of the program installed in the flash memory on the board.
5A terminal can be configured as "private" or "shared":
- a private terminal can display the operating status only of
the unit it is connected to via telephone cable;
- a shared terminal can display the operating status of all the
units connected in the network.
6Each board can “talk” to a maximum of 3 terminals; in common
applications, generally no more than two are used: one fitted on
the unit and another optional remote terminal configured as
share terminal.
The priority on the remote share terminal is always the display of
the alarms, even if when the alarm is activated the terminal is dis-
playing the parameters from another unit.
7To be able to communicate over a local network, the units must
be configured so as to be able to send the other units the
required information for correct operation.
In this regard, the first step involves assigning a progressive
number to the different units (1, 2, 3,…10) and then correctly
setting the addresses of the various terminals and LAN boards,
and making the electrical connections, step-by-step, as
described in the following paragraphs.

15
English
TERMINAL EVOLUTION
MOST COMMON CONFIGURATIONS AIU
1 Up to 10 units connected in the network with just one
remote share terminal
In this configuration, a power failure on the first unit will cause
the terminal to shutdown, and therefore the information corre-
sponding to the units in the network can no longer be read.
Nonetheless, the other units in the network would continue to
operate normally.
2 Up to 10 units, each with its own terminal
3 Up to 10 units, each with own terminal, with just one
shared remote terminal

16 English TERMINAL EVOLUTION
ELECTRICAL CONNECTIONS AIU
CONNECTION BETWEEN PC01 BOARDS AIU
The electrical connections must be completed when the units are
off and disconnected from the power supply.
The network can have different configurations, according to the
maximum distance of the connections between the boards and
the remote terminal; for the connections between the remote
terminal and the main board, a 'T' shunt may be required, as
shown in the drawing.
If both the jumpers are installed between 2 and 3 the flow of cur-
rent is interrupted between the connectors separated by the
dashed line.
If power is required on all the connectors, both the jumpers must
be installed between 1 and 2.
Terminal 0 is an auxiliary terminal and can be used to earth the
shield of the cable; the 'T' shunt must in any case be connected to
a metallic part of the unit that is already earthed.
MAXIMUM DISTANCE BETWEEN THE TERMINAL
AND THE BOARD
1For local terminals the connection to the main board is already
made using a 3-pair cable and 6-pin telephone connector. The
length of this cable generally does not exceed 3 metres.
2The remote terminals can be connected to the main board
using the type of telephone cable described in point 1, with a
maximum distance of 50 metres.
3For greater distances, up to a maximum of 200 metres, a shield-
ed cable must be used (six lead cable with shield and twisted
pairs, AWG24, resistance < 80 ohm/M). The cable may have 3
or 2 pairs, depending on whether the power needs to be sup-
plied to the terminals. The cable is not supplied by CLI-
MAVENETA HOME SYSTEM s.r.l.
AWG 24 cables with two twisted pairs plus shield, such as the
Belden 8723 or 8102, and AWG 24 cables with three twisted
pairs plus shield, Belden 8103 or similar, are recommended.

In this configuration, the local terminal is already connected to
the main board using a telephone cable.
To complete the network wiring, the control boards should be
connected in parallel using a shielded cable and with terminal J11
as the reference, as shown in the figure.
IMPORTANT: the polarity of the network must be observed:
The RX/TX+ on one board must be connected to the RX/TX+
on the other boards; the same is true for RX/TX-.

English
TERMINAL EVOLUTION
The shield on the shielded cable is earthed at a single point in the
network.
Earthing the cable at different points in the network may cause
control malfunctions.
The connection must be made, where possible, by fastening the
cable with a metal clamp, as shown in the figure on the left.
Alternatively, use the twisted end of the shield, as long as the
length of the earthed shield is a short as possible and a locking
washer is used (figure on the right).
The following pages shows the diagrams for a series of boards
connected to the network, powered by the transformers
installed in the electrical panel for each unit.

1 the use of two 'T' shunts: one fitted on the unit and one near
the remote terminal;
2 the use of the 3x2 shielded cable, so that the power to the
remote terminal is also supplied by the board on unit 1, con-
nected using the 'T' shunt;
3 near the terminal, insert the ferrite to reduce any electromag-
netic disturbance.
