The Energy Manager is a device used to record the temperatures measured at different points in the system. It can use the flow rate signals coming from optional transmitters to calculate energy balances in real time. The Energy Manager features an alphanumeric display with eight buttons and is powered by a 24 V dc signal. Up to four Platinum RTDs (Model 46917) can be connected to the inputs of the Energy Manager. Output relays and 4-20 mA outputs are also part of the device. The device can be programmed using a computer and a serial cable.
