The S7751A Hand Held Tool (HHT) is used with W7751A,C,E Excel 10 VAV 1 Controllers. (NOTE: The HHT phase 1 cannot
communicate with the phase 2 devices, such as; FCU, CVAHU, RIO and VAV 2. The HHT can be used to view or modify
points, setpoints or parameters, perform diagnostics, and balance Excel 10 controllers. In stand-alone applications (not used
in conjunction with Care/LiveCare), the HHT performs the application configuration (hardware inputs and outputs and
software points) and balancing.
