The booster system can now be controlled by anexternal controller.Factory settingClosed-loop control.9.5.4 Setpoints (2.1.3)Fig. 27SetpointsDescriptionIn addition to the primary setpoint 1 (shown in the display 2 in theOperation menu), six alternative setpoints can be set for closedloopcontrol. It is furthermore possible to set seven setpoints foropen-loop control.As described in sections 9.7.3 Alternative setpoints (4.1.2) and9.7.4 Alternative setpoints 2 to 7 (4.1.2.1 to 4.1.2.7), it is possibleto activate one of the alternative setpoints by means of externalcontacts.Setting rangeThe setting range of setpoints for closed-loop control depends onthe range of the primary sensor. See section 9.7.7 Primarysensor (4.1.4).In open loop control, the setting range is 0 - 100 %.Setting via control panel1. Mark the Operation menu with .2. Mark Further settings with or , and press .3.

(This operatingmode can only be selected for variable-speed pumps.)• NormalThe pump runs at a set speed.• Min.The pump runs at a set minimum speed. (This operating modecan only be selected for variable-speed pumps.)• StopThe pump has been forced to stop.Pumps in manual operation are not part of the normal pumpcascade and speed control. The manual pumps are a"disturbance" of the normal control of Hydro MPC.If one or more pumps are in manual operation, Hydro MPC maynot be able to deliver the set performance.There are two displays for the function. In the first display, thepump to be set is selected, and in the next display, the operatingmode is selected.Setting rangeAll pumps can be selected.Setting via control panel1.
