Hecu +0300023EN rel. 1.2 - 14.12.2021
1. INTRODUCTION
1.1 General features
Hecu is a control system for complete management of condensing
units fi tted with BLDC compressors. The serial connection between
the condensing unit and the evaporators controlled by the MPXPRO
represents one of the main features of this solution, contributing to
the energy effi ciency and reliability of the entire system. The control
board is designed for DIN rail assembly and is fi tted with plug-in screw
terminals, as well as incorporating a driver for managing two electronic
expansion valves. Hecu sistema can manage both medium- and low-
temperature applications. The main unit can communicate with up to 5
evaporators. A user terminal (PGDe or pLDpro) is also available for service
or commissioning the system.
Main features:
• Management of medium- or low-temperature applications;
• Modulation of cooling capacity by BLDC compressor with inverter;
• Management of a fi xed-speed backup compressor;
• Management of two modulating fans;
• Card with built-in driver for CAREL unipolar valves;
• Serial communication with evaporators (max 5);
• RS485 serial for BMS;
• Floating suction pressure set point;
• Floating condensing pressure set point;
• Advanced algorithm for calibrated oil injection to the compressor;
• Advanced algorithm for calibrated liquid or vapour injection to the
compressor;
• Oil speed boost for oil return to the compressor;
• Oil recovery washing for oil return to the compressor;
• Vast confi guration of defrost functions;
• Suction and discharge superheat control;
• Ample confi guration of alarms.
