What is a .IQ4 file?
An .IQ4 file is a type of computer file used specifically with a system called the Trend IQ4E controller. This controller is a device that helps manage and control heating, ventilation, and air conditioning (HVAC) systems in buildings that are not used as homes, like offices or schools. The .IQ4 file contains a "strategy," which is essentially a set of instructions or settings that tell the controller how to operate the HVAC system efficiently.
The contents of an .IQ4 file include different modules, which are parts of the strategy, and each module has its own settings and connections to other parts. This setup helps the controller understand how to manage the building's environment based on the strategy provided.
To create, modify, or view the contents of an .IQ4 file, you would use a program called the Trend System Engineering Tool (IQSET). This tool allows users to design or change the strategies according to the needs of the building. Once a strategy is finalized, it can be transferred to the IQ4E controller using the same tool. The controller then uses its built-in software (firmware) to execute the strategy and manage the building's HVAC system.
The company behind these technologies, Trend Control Systems, is based in the United Kingdom and specializes in creating systems that help manage building environments.
In summary, if you need to work with .IQ4 files, you would use the Trend System Engineering Tool to handle tasks like creating and uploading strategies to the IQ4E controllers, which then use these strategies to control HVAC systems in non-residential buildings.
