7 GENERAL DESCRIPTION The Energy FIT System measures energy usage while monitoring coil performance to adjust a PICV to optimize coil performance. The PICV maintains the correct flow despite pressure changes and guarantees the flow and actuator position only change when demand requirements change or ΔT is outside of specification. The pressure sensors measure upstream and downstream pressure allowing the BMS to reduce system pressure to save pump energy when pressure drop is higher than the PICV s requirements. The Intelligence Interface calculates the BTU and displays the data via Bluetooth on an Android or iphone mobile device or sends it back to the BMS. The Energy FIT System is fully customizable and allows selection of components that work best to optimize the application s unique energy goals. For full use of the FowCon Energy FIT System it is recommended to download the App from AppStore or GooglePlay. In the App you may connect to the FIT system by tapping Connection and Search for systems around. Name your system and select Control type (i.e. control valve) and Product type (i.e. FIT) and Add to saved systems. Hereafter the App will display T1, T2, ΔT, P1, P2, ΔP, Flow, BTU and ΔT target.

Note 5: Above values are related to maximum flow rate setting of the valve and thereby defining the flow through the valve at maximum control signal, normally 10V. Values above do not relate to control signals below 10V. All above valves will have 1000 positions between the pre-set flow value and 0V if control range is selected to 0-10V. International recommends that the Energy FIT System is selected to ensure that the set maximum flow rates are minimum 50% of the rated valve maximum capacity. Page 8 of 12
