FlowCon FIT 15-250 mm (1/2”-10”) 1B95095 - 01/2023 Intelligent Interface Connection The FlowCon Energy FIT System includes the state-of-the-art FlowCon Intelligent Interface which is the controller of the FIT System. The In- telligent Interface is compatible with 24V AC/DC and calculates the BTU and displays the data via Bluetooth® on any Android or iPhone mobile device and includes fully integrated BACnet com- munication to and from the BMS and if FlowCon BACnet actuator is selected also to and from the PICV actuator. Be aware to connect according to wiring dia- grams page 4 and 5 to avoid loosing warranty. FlowCon App Download the FlowCon App from AppStore or GooglePlay and take full advantage of the FIT system. Information on ΔT, ΔP, flow and BTU is transferred. The FIT System will automatically detect if it is installed in a heating or in a cooling system as it will add T1 and T2 readings and cross-check the result. If T1+T2<135°F the system is seen as a cooling system and if T1+T2≥135°F it will be considered a heating system. Do not remove cover from Intelligent In - terface. Opening cover will void warranty. Sensor Kit Connection The FlowCon Energy FIT System includes two temperature sensors that should be installed as close to the coil as possible, within 0.3-3 meter (1-10 ft). T1 should be installed on the inlet of the coil and T2 on the outlet of the coil. Sensors are to be installed in 1/4” ISO ports. The tem- perature sensors connect via quick-connectors to the grey cables from the Intelligent Interface. Cable length is different for T1 and T2. T1 con- nects to the longer cable (3 meter / 9 ft) and T2 to the shorter (1 meter / 3 ft). In addition, the FIT System includes two pres- sure sensors that must be installed on or close to the PICV valve. P1 should be installed on the inlet of the PICV and P2 on the outlet. The pres- sure sensors connect via quick-connectors to the black cables from the Intelligent Interface. P1 and P2 have identical cable length (1 meter / 3 ft), but P1 cable will be marked with a white sticker.
