The EVD Evolution

By Anonymous -

Based on CAREL’s extensive experience in electronic valve drivers, EVD evolution is available as a “single” and “twin” driver, the latter able to control two valves independently, with the most commonly used refrigerants. Simple graphics and a series of LEDs offer an immediate overview of operating status and the main driver functions.


The EVD evolution offers:

High Performance: Sophisticated control functions and construction with advance materials for optimum management of refrigerant flow, even in the most critical conditions.
Multilanguage: System easy to understand and configure, with eight languages available in addition to english. 
Reduced Environmental impact: Compatibility with natural refrigerants  (CO2) and energy saving help reduce ozone layer depletion and greenhouse gas emissions.

A powerful removable graphic display (EVDIS**0) can be used to configure the driver, providing clear and immediate information on operating status and allowing the controller to be started the first time after selecting just four parameters:

  •   Refrigerant used
  • Application (chiller, cabinet, etc.)

EVD evolution can operate in stand-alone mode, or connected to a pCO or the PlantVisorPro supervisor for the integrated management of the driver via tLAN (EVD0000E00), pLAN (EVD0000E10) or RS485/Modbus (EVD0000E20).
EVD evolution can also manage other functions in addition to superheat control, such as hot gas bypass, evaporation pressure control (EPR), valve control for gas coolers in transcritical CO2 circuits.

CAREL and the dreaded 'NO LINK' Screen!

CAREL and the dreaded 'NO LINK' Screen! Picture the scene, you've just downloaded a fresh new piece of software onto a controller but rather than the a new interface, you're met with a big fat 'NO LINK' message on the display. Or maybe you've just ran a factory reset to default settings and have come up against the same issue?  These are all possible causes for the common problem encountered by many of our customers, deemed the 'NO LINK' screen! (capitals for emphasis) As well as the two already mentioned, other common causes of the issue are a result of: A faulty connection between the Controller and the Display A faulty Controller  In any case, this issue is relatively simple to fix and our Managing Director, Stefano - having been in the Industry for 15+ years - has put together a video guide on how to do so. Watch the video below to see how to overcome the dreaded 'NO LINK' Screen!   www.i-acs.co.uk

For those who think that the new generation of innovative, automated HVAC control systems are a far-off thought, think again!  The new c.pCO Range by CAREL marks the arrival of their most intelligent range of controllers yet. Despite their compact design, the c.pCO Controllers are packed with new and exciting technologies offering a highly integrated solution to any kind of BMS System.  The versatile nature of the new standard controller (2 Ethernet, USB & RS485 Inputs Built In) opens doors to a wide range of communication protocols such as Modbus, BACNet,  HTTP, FTP  and loads more. The video below offers a detailed look into the new features and benefits of the c.pCO range. Worried about having to do a lot of work to replace older controllers? As if this wasn't enough, all c.pCO Controllers offer pin-to-pin compatibility with pCO5+, pCO5 and pCO3 controllers.  Get in touch now for more information! Peter Campbell Marketing

1tool is the development system for the Carel programmable control platform, consisting of six different environments in which the designer manages the application software in all its different stages: from design to simulation, to testing and debugging, to arrive at commissioning in the field. A fundamental feature of 1tool is integration. Because all the different environments are interconnected to best support development of the application software. Each environment is in fact dedicated to the realisation of a specific function and interacts with the others to offer the designer: -  Greater reliability thanks to real-time error notifications in the design stage; - Reduced development time using the advanced functions offered, first and foremost the new libraries of functional modules specific for HVAC/R; -  Flexibility in terms of software customisation. All these features, an intuitive graphic interface and user simplicity make 1tool an excellent product, responding to th
