You cannot control hardware unless you link your logic to physical terminals.

Once connected, 1Tool transforms your laptop into a virtual control panel. Before using the software, proper installation is critical

✔ Enables remote access and diagnostics
✔ Provides full documentation and project version control
✔ Backward compatible with legacy Carel devices

Note: The controller usually needs to be in "Stop" mode to download, though some updates can be done in "Run" mode. Step 2: Downloading

Carel 1Tool is the proprietary integrated development environment (IDE) designed by the Carel Industries group for programming their range of HVAC/R (Heating, Ventilation, Air Conditioning, and Refrigeration) controllers. It serves as the primary interface for configuring, commissioning, and diagnosing Carel programmable controllers, including the c.pCO series, pCO5, pCO3, and related terminal units. The software is designed to streamline the workflow from logic design to field commissioning, offering a suite of tools for graphic visualization, parameter setting, and network integration.
