 "summary": "CONTECA EASY 750 is a heating and cooling energy meter. Through the Caleffi 755052 gateway it appears on BACnet MS/TP or BACnet IP as read-only Analog Inputs for heating and cooling energy, four pulse inputs (e.g. hot and cold water meters), power, flow, flow and return temperatures and an alarm/status word. Every value is mapped twice: AI 1-14 in SI units and AI 15-28 in imperial units.",
