FlowCon FIT-G DN40-50 (1 1/2”-2”) 11/2024 Flow Rate Table - FlowCon Green.3 16-600 kPaD · 2.3-87 psid l/sec l/hr GPM Setting Fitting and Re-fitting the Actuator The suitable actuator types are FlowCon FH and and FH.1 (failsafe). These are electrical modu- lating actuators. 0.528 1900 8.36 1.0 0.633 2280 10.0 1.1 0.738 2660 11.7 1.2 0.843 3030 13.3 1.3 Do not connect power to the actuator unless 0.947 3410 15.0 1.4 the actuator is already fitted on the valve 1.05 3790 16.7 1.5 and NEVER install the actuator in closed 1.16 4160 18.3 1.6 position – this may damage the valve. 1.26 4540 20.0 1.7 Actuator is supplied in open position to en- 1.36 4910 21.6 1.8 sure easy commissioning of the system. 1.47 5280 23.2 1.9 1.57 5650 24.8 2.0 Mount the actuator on the valve and finger tight- 1.67 6010 26.4 2.1 en the connection union. Do not use additional 1.77 6370 28.0 2.2 tools. In case the actuator will have to be removed, 1.87 6730 29.6 2.3 it is recommended to electrically open the actua- 1.97 7080 31.2 2.4 tor for easier removal. Hereafter finger loosen the 2.06 7430 32.7 2.5 connection union. Again, no need for additional 2.16 7780 34.2 2.6 tools. Please make sure that the actuator is elec- 2.25 8120 35.7 2.7 trically opened, before re-fitting it on the valve.

FlowCon FIT-G DN40-50 (1 1/2”-2”) 11/2024 Orientation Upside-down installation is allowed along with the standard horizontal and vertical installation (figure 5). If insulated, please include the con- nection union to eliminate condensation from the valve. 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.
