1. INTRODUCTION
1.1 Main features
Heos is a control system for the complete management of showcases or
cold rooms in which the compressor (variable speed or on/off ) is cooled
by a water loop.
The control board is ready for DIN rail assembly, is fi tted with plug-in
screw terminals and comes with a built-in electronic expansion valve
driver.
In order to manage multiplexed showcases, Heos can manage a local
Master-Slave network comprising a maximum of 6 units (1 Master and 5
Slave). Each controller can be fi tted with its own display (PLD) and/or user
terminal (pGDe), for service or commissioning.
Main features:
• board with built-in driver for CAREL single-pole valve;
• modulating management of cooling capacity by inverter on BLDC
compressor;
• stand-alone or multi-evaporator management;
• automatic balancing of cooling capacity in multi-evaporator
confi guration;
• COP calculation and management;
• advanced superheat control with protection against low superheat
(LowSH), low evaporation temperature (LOP), high evaporation
temperature (MOP) and low suction temperature (LSA);
• defrosts can be activated from the keypad, digital input, via network
from the Master, or supervisor;
• various types of defrost available: electric heater, reverse cycle, hot gas;
• smart defrost functions;
• coordination of network defrosts;
• management of lights and curtains;
• anti-sweat heater modulation;
• evaporator fan speed modulation;
• possibility to display and set Slave parameters from the Master;
• sharing of one or more network probes (e.g. network pressure probe);
• HACCP alarm management;
• RS485 serial for BMS inside.
