1tool is the new development tool for the CAREL programmable controller platform. It features five different environments available to the designer for managing all phases of the application program: from design to testing and debugging and right up to commissioning in the field.

The fundamental aspect of this tool is integration: all the environments are linked together to best support development of the application program.
Indeed, each environment is dedicated to the development of a specific function and interacts with the other environments so as to ensure the designer:

• greater reliability, thanks to the real time error notification in the design phase;
• a reduction in development times using the new functions available, above all the new libraries of functional modules;
• flexibility in terms of software customisation.

All these features, new graphics and userfriendliness make 1tool an excellent product that responds to a variety of needs for HVAC/R applications.
