How do I configure the equipment and I/O terminals?

Access equipment configuration by swiping left to the Quick Access screen, tapping Config > Equipment > Equipment & I/O. Select your equipment type (Fan Coil, Conventional, or Heat Pump), configure the valve types and fan speed. Then tap I/O Assignment to assign terminals to their functions. The thermostat provides default assignments based on equipment selection, but you can override them by tapping the plus button next to each terminal.
