To access the Installer Setup (ISU) menu on a Honeywell VisionPro 8000 to configure equipment parameters, press the Menu button, tap Preferences or Installer Setup, and enter your specific security access code (which is typically derived from the device's date code or installer ID). From this advanced menu, you can configure your exact system type (conventional vs. heat pump, number of heating and cooling stages), fan control options, and specialized indoor air quality accessory settings.
