 "summary": "The System-1000 is a one- or two-channel BTU meter with native BACnet MS/TP or BACnet IP. Per channel it exposes energy rate, flow, supply, return and delta temperature, an aux input and COP as Analog Inputs, and energy, volume and aux totals (non-resettable, year-to-date, previous year and resettable user totals) as Analog Values. Binary Inputs give mode, alarms and a system fault.",
