FlowCon FIT DN15-250 (1/2”-10”) 12/2024 -2 Fitting and Re-fitting the Actuator The suitable actuator types FlowCon SM.0.0.0.3, SM.0.0.0.4 (failsafe) and SM.0.0.0.6 (failsafe and BACnet) are electrical program- mable actuators. It is recommended to grease the O-ring on the spindle adaptor with silicone grease before plac- ing the spindle adaptor on the valve spindle. Then place the actuator on the spindle adap- tor and place the three actuator “legs” into the three holes in the mounting bracket (figure 2 and 3). Make sure that the snap ring is clicked onto the mounting bracket, so that the snap ring is locked at the top of the mounting bracket, but still able to rotate. Then finger-turn the snap ring counter clockwise (upside view) approximately 1/6 of a turn until its stop points touch the ac- tuator “legs” and the mounting is locked with a (small) click. Do not use additional tools. It is essential that the actuator runs linear flow control mode, 2-10V DC. Spindle adaptor Snap ring The bottom side of the actuator In case the actuator will have to be removed, it is recommended to electrically open the valve for easier removal. Hereafter reverse the proce- dure and turn the snap ring clockwise until the actuator is loosened and lift the actuator up. Again, no need for additional tools. Figure 4 Do not remove cover from actuator. Opening cover will void warranty. Remember to remove the protection film from the actuator display to avoid condensation.

FlowCon FIT DN15-250 (1/2”-10”) 12/2024 -2 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 device and includes fully integrated BACnet communication to and from the BMS and if FlowCon BACnet actuator is selected also to and from the PICV actuator. 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). 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. 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.
