iACS - Experts in AHU Controls

With its residential air-conditioning solutions, Carel represents a reliable and innovative technological partner for manufacturers of heat pumps and all operators (manufacturers, installers, system integrators) who want to offer an integrated controller for indoor comfort at home and domestic hot water production systems, focusing on energy efficiency, respect for the environment and optimization of resources, as well as easy operation and complete user satisfaction. To achieve these results, Carel pays special care to technological innovation, usability and access to information. Technological innovation pCO sistema+ allows management of variable speed compressors with DC inverters that, when combined with electronic expansion valves , ensure the most extensive modulation of heating and cooling capacity currently available, maximizing residential air-conditioning system efficiency in response to different comfort requirements and different climatic conditions throughout

Carel's response to the needs of HVAC installers and manufacturers was the design of an entire range of increasingly advanced probes.  The range envisions temperature and humidity sensors with different uses, housed in sockets, ducted, residential or industrial environment, pressure transducers , smoke, fire and flood detectors, air quality probes , gas leak detectors for refrigerant units, guaranteeing performance and compatibility with all Carel controllers . Advantages Carel probes, as well as being characterized by the acknowledged performance that sets them apart, are very versatile and can satisfy various market requirements. In fact, all the probes have been especially designed to be compatible not only with all Carel controllers, but also with the most commonly used standards worldwide. The temperature and humidity probes, offering a great choice between active and passive technology, are available in different operating ranges and also in specific versions

After the great success of the IR32 controllers, Carel offers a new generation for refrigeration controls. With the new IR33 , Carel now offers: infrared remote controller programming key High performance green display Led RS485 serial board And all of this, keeping the same dimensions as the ir32! The ir33 also manages smart defrost, resulting in great energy savings for the entire insallation. This controller now automatically manages the monitoring of the unit, highlighting any critical situation. It warns when the alarm exceeds its limits, saving the main information to a permanent memory. 

We have released the Tridium Jace interface profile in Modbus available Free Of Charge for you to download. This will grant a 5 minutes integration job with a Tridium BMS system Including ALL THE GRAPHICS!! Check it out on our YouTube channel.

"One panel fits them all"  3 sizes, great flexibility:  5,5Kw ,   15Kw &   30 Kw The answer from Carel to a high customizable product such as electrical panels for Air Handling Units, has been the " Masteraria " with its revolutionary Snap-ON MCB system from Muller and a highly flexible control software. This made possible the one Control box to manage simple and complex AHUs with fans up to 30Kw. The Masteraria is a compact Electrical panel for AHU which, thanks to its powerful embedded software is able to accommodate any simple and complex configurations of Air Handling Units: 2 Contactors for Supply and Extract fans (from 0.09Kw  to 30 Kw each) IP65 protection for indoor and weather-proof installations 1 Extra contactor 230V/1ph for :            - External interfaces            - Power Sockets            - AHU internal lighting             - Heat wheel control Boxes BMS enabled for Bacnet , Lon , SNMP , Modbus , K

The Masteraria Control panel for AHUs installations are spreading out across the UK territory on very prestigious building sites. The latest installation last month has been on the Wellington Arch , in the heart of London, right next to the Royal Palace. The Carel Electrical panel, equipped with a PCO3 controller ,  manages the thermo-higrometric conditions in the building guaranteeing a precision control. The dampers, Heating coils, the DX condensing units, are controlled by Masteraria panel making sure that the overall running efficiency of the AHU package it's at its best.  Thanks to the 3 embedded comms ports of the PCO3 controller and the hi-tech MODBUS integrated Inverter (VFD) management of the new AHUE software, the Masteraria panel monitors the fan speed and airflow through a Modbus interface link, making available the inverter references straight from the semi-graphical, intuitive and user fridley display of the AHU controls. i-A.C.Systems , the excl
