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.
