The new generation of air-conditioning controllers

Product catalog summary

Introduction
CAREL, a leader in chiller and heat pump control, is introducing a new generation of air-conditioning controllers, the µC2. This controller offers advanced technology and software at competitive prices.

Specifications
The µC2 controller features a modern ergonomic display and an innovative local network (tLAN) that interacts with the electronic expansion valve driver and a redesigned expansion board for DIN rail. It can manage up to 4 hermetic and 2 semi-hermetic compressors across 2 circuits, with one electronic expansion valve per circuit.

Technological Advancements
New functions include EEV management, smart defrost, and buffer tank suppression, which reduce energy consumption and production costs. An optional clock board allows for time band management, low noise operation, and data logging. The µC2 is available in panel and DIN rail versions, supporting ratiometric pressure transducers for improved performance and cost savings.

Connectivity
The redesigned serial interface board is smaller and more cost-effective, allowing easy installation. The integrated Modbus® protocol enables connection with widespread BMS systems.

Technical Characteristics
- Supply voltage: 24 Vac -15 to 10%, 50/60Hz
- Maximum power input: 3 W
- Digital inputs: 5 free contacts (2 multifunction)
- Analog inputs: 4 (3 NTC inputs, 1 configurable as NTC/ratiometric pressure probe/digital input)

Application
The µC2 controller is suitable for managing up to 4 compressors and offers flexible electrical wiring solutions.

Conclusion
CAREL's µC2 controller represents a significant advancement in air-conditioning technology, offering enhanced efficiency, connectivity, and cost-effectiveness.

The new generation of air-conditioning controllers-1

CAREL,a leader in the sector of chiller and heat pump control,is planning to upgrade its controllers and offer its customers new technologies and increasingly evolved software at increasingly competitive prices. For this reason, a new controller has joined the wide rangeof CARELs air-conditioning solutions:new ҵ C C յ C > 2 ,characterisedby a modern ergonometric display with a high degree of efficiency, and by an innovative local network (tLAN) that interacts with the new generation driver for the electronic expansion valve and with the expansion board (for the second circuit), completely re-designed for the DIN rail. The current > 2 can manage up to 4 hermetic and 2 semi-hermeticcompressors for a total of 2 circuits, with the possibility to manage one electronic expansion valve per circuit. The new technologically advanced functions, like the EEV management, the smart defrost and the buffer tank suppression, reduce energy consumption and the production costs of the OEMs. The new optional clock board allows management of time bands and other innovative functions such as low noise operation mode and data logging. > 2 is available in both panel and DIN rail versions.It allows easy connection solutions and gives the opportunity to use the new technology of the ratiometric pressure transducers, with the advantages of improved performance and cost savings. The serial interface board, completely re-designed and featuring smaller dimensions and reduced costs, allows a simple and rapid installation even after the control had been installed. Finally, thanks to the integrated Modbus > protocol, it is possibleto connect ε C > 2 with the most widespread BMS systems. >
