FlowCon FIT-G DN15-32 (1/2”-1 1/4”) 11/2024 Orientation Upside-down installation is allowed along with the standard horizontal and vertical installation (figure 5). 360º Figure 5 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 de- vice and includes fully integrated BACnet com- munication to and from the BMS. 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 Inter - face. 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 tempera- ture sensors connect via quick-connectors to the grey cables from the Intelligent Interface. Cable length is different for T1 and T2. T1 connects to the longer cable (3 meter / 9 ft) and T2 to the shorter (1 meter / 3 ft). Optionally, the FIT System may include two pressure 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 pressure 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. 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.
