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
Free-cooling management
Defrost and anti-freeze function
Double setpoint that can be enabled through an external contact
Compensation of the dynamic setpoint
ump-down management
Integrated programming with 2 daily programmes
Control of the linear or step condensation/evaporation pressure
Operation with one, two, or no circulation pump
One, two, or no source circulation pump
