Page 6: Introduction
INTRODUCTION Introduction The programmable controllers in the c-pro 3 nano CHILL 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-PRO 3 development environment. -
