Map data points exchanged between the main controller, electronic expansion valves (EEVs), variable frequency drives (VFDs), and building management systems (BMS). Architecture of a 1tool Project
Watch and modify sensor values, setpoints, and digital flags during execution to verify logic flows.
Run application logic on a PC without connecting physical hardware.
In the rapidly evolving world of HVAC/R (Heating, Ventilation, Air Conditioning, and Refrigeration), precision control and system customization are critical. The CAREL 1tool software stands out as the cornerstone development environment for managing and programming CAREL’s programmable controllers, such as the pCO, c.pCO, and pGD platforms. carel 1tool software
is CAREL’s proprietary software suite designed for the development of HVAC/R control applications. Unlike basic configuration tools that only allow you to toggle existing parameters, 1tool is a full-fledged development environment. It allows engineers to design a system's logic from the ground up using a graphical, functional-block approach.
1tool uses a highly intuitive Function Block Diagram language. Developers drag and drop blocks representing mathematical operations, logical gates, PID controllers, and specialized thermodynamic algorithms (e.g., electronic expansion valve control, compressor management), connecting them visually to establish data flow. 2. Extensive HVAC/R Library
1tool is a professional tool designed for OEM (Original Equipment Manufacturer) engineers, system integrators, and panel builders who design and build HVAC/R equipment. The applications developed with 1tool are ubiquitous in modern buildings and industrial processes: Map data points exchanged between the main controller,
Use standard industry symbols for fans, pumps, compressors, and valves.
Utilize a comprehensive library of thermodynamic equations, compressor envelopes, and electronic expansion valve (EEV) logic. 2. Core Modules Within the 1tool Environment
Unlike generic automation programming tools, 1tool is built from the ground up with HVAC/R logic in mind. It bridges the gap between complex computer programming and practical thermal control logic, enabling engineers to develop tailored solutions for chillers, air handling units (AHUs), heat pumps, and compressor racks. Core Features and Capabilities In the rapidly evolving world of HVAC/R (Heating,
1Tool is the primary IDE (Integrated Development Environment) for Carel’s programmable controllers. It supports:
Thoroughly test sensor failures, out-of-bounds temperature values, and alarm loops in the simulator before downloading the software to physical hardware.
