Carel has extended the range of programmable controllers pCO5+

The range of Carel pCO programmable controllers for the management of HVAC/R applications and systems has been extended with the addition of pCO5+ HS (High Speed): the efficiency of HVAC/R systems now with a faster response.

Speed and performance

The new pCO5+ HS guarantees improved performance both in terms of application times (start-up and cycle) and upgrade speed.

This improved controller performance translates into faster unit set-up. When commissioning in the field, system management is also much faster.

Native integration of the USB port further simplifies maintenance: the data logger files saved on the controller can be simply and quickly copied to a USB flash drive or PC, for detailed analysis.

Last but not least, the calculation speed of the pCO5+ HS means it can respond more quickly and precisely to variations in the main unit input values (temperature, pressure, humidity, etc.).


pCO5+ HS comes with two built-in serial interfaces, two expansion slots and two USB ports. The controller also features a wide range of optional cards for managing the communication protocols typically used in HVAC/R (Modbus, Carel, BACnet, LonWorks, KNX, HTTP, SNMP). Communication with CAREL apps can also be implemented using 1tool.

Energy saving

pCO5+ HS is available in a version with two built-in electronic expansion valve drivers and an optional Ultracap module, for integrated energy saving management.

It also exploits the advantages of the pCO platform in terms of energy efficiency: possibility to connect to devices such as electronic valve drivers, power+ for managing DC compressors, integration with the CAREL IoT portal for diagnostics and predictive maintenance and machine learning optimisation logic.

Backwards compatibility

pCO5+ HS guarantees perfect compatibility with the entire range of pCO3 and pCO5 controllers, in terms of both hardware (pin-to-pin compatible) and software, so as protect and guarantee the investments made by CAREL’s customers. Furthermore, Carel software (1tool, pCOManager, SmartKey Programmer) can be used to load the binary files onto the new pCO5+ HS.


The higher performance of the pCO5+ HS makes the controller ideal for the following applications:

  • Chillers (with screw or centrifugal compressors)

  • Process chillers (where it is important to guarantee constant temperature and humidity)

  • Data centres
