Mark the Settings menu with .2. Mark Secondary functions with or , and press .3. Mark Fixed inlet pressure with or , and press .4. Set the inlet pressure with or , and save with .5. Mark Activated with or , and press . Theactivation is indicated by a check mark in the box.Factory settingThe function is deactivated.9.7.40 Flow estimation (4.3.23)TM04 6200 5009Fig. 85Control sourceDescriptionHydro MPC can be remote-controlled via an external busconnection (option). See section 9.8.2 GENIbus. Control of theHydro MPC can also take place via the bus connection. Forfurther information, see section 9.8 Data communication.In this display, the control source, CU 351 or the external busconnection, is selected.Setting via control panel1. Mark the Settings menu with .2. Mark Secondary functions with or , and press .3. Mark Control source with or , and press .4. Select the desired control source with or , and savewith .Factory settingThe control source is CU 351.Fig. 87 Flow estimationDescriptionAs described in section 9.7.37 Pump curve data (4.3.19), theCU 351 can optimize operation according to performance curvesand motor data. In this display, curve types are selected whichthe CU 351 will use for the optimization if they are available.TM03 8977 480754
