1INTRODUCTION
1.1 Introduction
The programmable controllers in the c-pro 3 nano CHIL line are devices designed to manage chillers/heat pumps with single and dual
circuit with a maximum of three scroll compressors per circuit.
They use programmable controllers, the expansions of I/O, and the remote user interfaces of the c-pro 3 line and are programmed
with a software application implemented with the UNI- RO 3 development environment.
The controllers can manage chillers/heat pumps with air/water and water/water; thanks to the CAN communication port the controllers
can also communicate with an external driver (EVDRIVE03) for bipolar stepper electronic expansion valves.
They can be powered with alternating current (12 VAC). The programming port allows upload and download of the configuration
parameters (using a regular pen drive); using the RS-485 port with the MODBUS communication protocol instead you can connect the
devices to the arameters Manager software setup system or to that for monitoring and supervising the systems with Internet
CloudEvolution. Lastly, with the CAN communication port you can connect the devices to the expansion of I/O, to the remote user
interface, and to the external driver of the electronic expansion valves.
The application programme can manage air/water and water/water, single-circuit, or dual-circuit units.
Some of the numerous control functions offered are listed below:
Functions Availa le
Management of a maximum of three scroll compressors per circuit
Management compressors with cooling – heating mode
Fan management with phase cutting speed module
EVDRIVE03 management with electronic valve for each circuit

6.1 Passwords
Each menu is assigned a level that represents the accessibility to the different menus.
A password is assigned to each level that grants access to the different functions offered by the menu; after having entered the correct
password, the protected functions become accessible. The entry of the correct password has two consequences:
•unlocking of the relative level;
•unlocking of its sub levels.
All the level passwords may be modified from the same level or higher levels. For example, from the manufacturer level you can
change all the passwords of the lower levels using the appropriate page.
The range of values that can be set for a password is -999/9999
Once four minutes have elapsed without having pressed any key, the password expires and you have to reset it.
