Software !free! - Carel 1tool

Unlike generic PLCs (Programmable Logic Controllers), 1tool features pre-tested thermodynamic logic blocks, drastically reducing development time.

: The environment is autonomous, ensuring the privacy of your custom-developed algorithms.

: The most basic, fundamental logic elements (e.g., Boolean AND/OR gates). Macroblocks

Enter —a unified, proprietary programming and monitoring environment designed to bridge the gap between hardware capability and operational usability. Whether you are an OEM (Original Equipment Manufacturer) designing a new unit or a field technician servicing a refrigeration rack, understanding 1Tool is essential.

Modern HVAC/R systems do not operate in isolation. CAREL 1tool provides native support for configuring extensive network architectures, enabling seamless integration into Building Management Systems (BMS). Supported protocols include:

A critical part of any HVAC/R unit is how the end-user or technician interacts with it. The UI Editor allows developers to design the screens for local displays (like the pGDE or pGDN displays) and touchscreens. It features a WYSIWYG (What You See Is What You Get) interface to easily position text, variables, animations, and alarms. 3. Network Editor
