File TypeIQ4E Controller Strategy File
What is an IQ4 file?
An IQ4 file contains a strategy used to configure the operation of a Trend IQ4E controller, which is used to control, monitor, and optimize a HVAC system in a non-residential building. It stores strategy, which is a configuration for how the controller operates. IQ4 files include module instances, along with their parameters and links.
Strategies are created and configured using the System Engineering Tool (IQSET). The strategies, which are stored in IQ4 files, can be uploaded and downloaded using IQSET. Strategies that have been downloaded are stored in the controller and run using the controller firmware.
