C-PRO NANO HARDWARE MANUAL
1 Introduction
The C-PRO NANO family of programmable controllers is the ideal solution for refrigeration, ventilation and
air conditioning applications in low complexity situations. Both in terms of regulation operations and the user
interface, the controller software is fully programmable, in a simple and intuitive manner, thanks to the use of
the UNI-PRO development environment.
The C-PRO NANO is manufactured as a panel installation version.
Using the 6 relay outputs, it is possible to control various types of devices such as compressors, water
circulation pumps, defrosting elements, condensation or evaporation fans, cycle inversion valves, alarm
warning indicators etc. The control process makes use of NTC probes for monitoring temperature and
0/4-20 mA or 0-5V ratiometric transducers for monitoring pressure. There are two alternative versions
according to the kind of Bus used: CANBus version and IntraBus version.
The C-PRO NANO is also equipped with digital inputs for monitoring unit functions; and it is also possible to
connect until two I/O expansion units (IntraBus version) or the expansions of the C-PRO EXP-MICRO, C-PRO
EXP-KILO, C-PRO EXP-MEGA, C-PRO EXP-GIGA families to increase the I/O (CAN version).
All the parameters may be adjusted from the user interface, and it is possible to upload and download
configuration data by means of a programming key.
The display has four red-coloured digits (plus decimal points) and 16 icons of various colours; the keypad has 4
keys.

3 Technical characteristics
3.1 Connections
Power supply:
The C-PRO NANO is powered by a 12 V AC supply. It may also be powered by a 12 V DC supply; in this
case, there is no option for controlling the fan cut-off modules. The maximum length of the power supply
connecting cables is 1 m.
Analogue input connections:
The C-PRO NANO has two analogue inputs for NTC probes and two for NTC probes or for 0/4-20 mA or 0-5V
ratiometric transducers. Selection is made by the UNI-PRO development system. The current transducers may
be supplied by means of the 12 V DC terminal (refer to the physical layout) with a non-stabilised voltage equal
to 12 V DC. The maximum length of the analogue input connecting cables is 3 m.
Digital input connections:
The C-PRO NANO has 5 non-optoisolated digital inputs (clean contact). The maximum length of the digital
input connecting cables is 3 m.
Digital output connections:
The C-PRO NANO has up to 6 electromechanical relay digital outputs. The maximum length of the digital
output connecting cables is 3 m.
Analogue output connections:
The C-PRO NANO has 1 pulse modulation analogue output to drive the cut phase modules. The maximum
length of this analogue output connecting cables is 1 m.
The C-PRO NANO has 2 voltage or current (optional) analogue outputs. The maximum length of these
analogue outputs connecting cables is 3 m.
Remote terminal connections (IntraBus):
The connection between the C-PRO NANO and the terminal is made using a 3 way cable. The maximum
length of the terminal connection cables is 1 m if using a DC supply from the controller; 30 m where the wallmounted keypad is supplied using a separate transformer.
Remote expansions connection (IntraBus):
The connection between the C-PRO NANO and the I/O expansion units is made using a 3 way cable. The
maximum length of the remote I/O expansion units connecting cables is 1 m.
User interface connections (CAN):
The connection between C-PRO NANO and the remote user interface is made using a 2 way cable (better if it
is two weaved couples) plus possible ground.
The maximum length of the connection cables to the remote user interface depends of the CAN port baud rate .
- 1.000 m with 20.000 baud
- 500 m with 50.000 baud
- 250 m with 125.000 baud
- 50 m with 500.000 baud.
The CAN port baud rate is settable by parameter.
Page 6
C-PRO NANO HARDWARE MANUAL
Connection with a remote expansion (or an other CAN controller) :
The connection between C-PRO NANO and the remote expansion (or other CAN controller) is made using a 2
way cable (better if weaved) plus possible ground.
The maximum length of the connection cables to the remote controllers or expansions depend on the CAN port
baud rate (see above section “User interface connections”)
C-PRO NANO and the expansion ( or other CAN controller) power supplies has to be electrically
insulated one from the other.
Notes on the electrical connections
- do not use electric or pneumatic screw-wrenches on the terminal board
- if the device has been moved from a cold to a warm environment, condensation may have formed
inside; please wait approx. one hour prior to switching on
- ensure that the voltage, frequency and operational power of the device are compatible with the local
power supply
- disconnect the power prior to proceeding with any kind of maintenance operation
- do not use the device as a safety device
- for repairs and any information relating to the device, contact the Evco dealer network.
Caution
The instructions governing maximum connecting cable lengths imply that a range of precautions are being
observed:
In order to avoid exemption problems, it is good practice to comply with the following instructions:
- Avoid locations with antennae
- Avoid cabling probe inputs and relay outputs together; generally avoid mixing low and high voltage
signals
- Avoid wrapping cabling around power components
In order to avoid safety problems, it is good practice to comply with the following instructions:
- Avoid premises with relative humidity >90%
- Avoid water
- Avoid corrosive environments
- Avoid explosive environments
Special recommendations
Finally, ensure that the operating conditions are within the limits of use described in the technical
characteristics.

“V-VIEW” user interface (with a alfanumeric 4 x 20 characters LCD display) can be connected to the CAN
port of the C-PRO NANO controller. On request a graphic 240 x 128 pixel LCD display (V-GRAPH) user
interface is also available .
6.2.1 V-VIEW
The visualized text on the LCD display, the LEDs and key functions of the user interface are realized with
UNI-PRO software development system and use a “browser” technology to load the C-PRO MICRO pages and
to refresh the visualized variable value. The user interface is directly interfaced with the controller without
downloading any software.
The typical implemental functionality are :
• intuitive navigation with “ browser style”
• text and icon combination
• tables utilization with “scroll” possibilities.

The cut-off module allows the control of single-phase fans with a maximum current equal to 5 A. The fan
module live feed must be the same as that feeding the controller.
If the C-PRO NANO has a DC power supply, then it is not possible to control the fans using the EVDFAN1.
Example:
V AC = 230 V
I max = 5 A
VA (max) = 230*5 = 1150 VA
W (max) = 230*5*cosφ = 1150 Watts if cosφ=1

7 CAN Connection
C-PRO NANO can be connected to other controllers, to expansion modules and to one or more user interfaces
using either local or wide CAN serial port. The CAN bus uses the ISO 11898 standard, a balanced two-wire
communication very similar to the RS 485 standard.
Resistors with a recommended rating of 120-124 ohm have to be fitted at each end of the bus.
120ohm
If connection is established through the Local CAN bus, it is possible to power a user interface using the 4terminal connector, according to the following table:

7.1 Notes on the parameter of the controller relative to the CAN net
configuration
To log on the controller parameters configuration procedure relative to the analogic output act in the following
way :
Both for the remote or built-in user interface :
1. Ensure that the controller and the user interface are both switched on and no utilization is connected
with the analogic output
2. Keep pressed at the same time and buttons for two seconds : the first available voice
will be visualized (the voices are relative to the controller; for the voices relative to the user
interface repeat the selection from “reset”).
To select the controller parameters relative to the CAN network configuration:
1. Press and release button to select “CAN” voice.
2. Press and release button: if the controller is visualizing the net parameters, the voice “Input
Password” will be visualized: in this case see the following 3. and 4. (in opposite case see directly point 5.).
3. Press and release button: the cursor blinking.
4. Press and release button to set “ -19”.
5. Press and release button: the first voice available will be visualized.
To select a parameter:
1. Press and release button
To modify a parameter:
1. Press and release button: the cursor blinking.
2. Press and release or buttons to select the value
3. Press and release button to confirm the selection done.
4. Switch – off the controller.
For a quick closing procedure :
1. Press and release repeatedly button

C-PRO NANO HARDWARE MANUAL
The main parameters of the CAN net are the following :
• “My Node” (represents the data sender ID )
• “Network Node” (represents the receiver ID)
• Baud rate (represent the data transmissions speed; initially it can be useful to let this value
set at “Auto”; in this way the device will try to connect a few time with different speed)
• Master (represents network operation) when instrument is set as master it checks device network to find
Devices presence. A controller with I/O expansions needs to have MASTER = TRUE.
Predefined value :
• the parameter My Node for a controller is set at 1
• the parameter My Node for an expansion is set at 2
• the parameter My Node for a user interface is set at 99.
Every device in the network represents a knot (the maximum knot numbers are 32); each knot has an ID (the Id
range is from 1 to 127).
Every device in the network has to be set as regards the network components through “Network Node”
parameters.
Example:
If a controller, an expansion and a user interface are installed, set the following value on the controller in the
following way :
1. Assign at “Network Node 1” the address “2” (expansion).
2. Assign at “Network Node 2” the address “99” (user interface).
Repeat the same operations for the expansion and the user interface.
ATTENTION: the parameters as regards the net could be overwritten by the application software.
