 "summary": "The 670066 base module is the BACnet MS/TP option for the older MULTICAL 62/601/602/6L2/6M2/801 meters. It serves 12 read-only Analog Inputs: meter number, heat and cooling energy, volume, flow, power, two pulse inputs, the info code and the flow, return and difference temperatures. MULTICAL 403/603 meters use a different module (HC-003-66) with a larger object list.",
