The controller is pre-configured for filling, allowing for quick and easy installation with its plug-and-pump capabilities. For other applications, the controller offers multiple control modes that can be selected and configured through the Grundfos GO app.\u003c\/p\u003e\n\u003cp\u003eThe pump can be operated via the keypad on the controller interface, and the display provides system status, alarms and warnings, and pump performance data. CU 202 starts and stops the SQFlex, using soft start, based on information about water consumption from either a level or pressure signal.\u003c\/p\u003e\n\u003cp\u003eBuilt-in Bluetooth enables commissioning and configuration through the Grundfos GO app. Remote monitoring is available through Wi-Fi, GENIbus or Modbus, using Grundfos Connect or another SCADA system, saving inspection time. Communication between the pump and controller occurs via the power supply cable (mains-borne signalling), eliminating the need for extra cables. The CU 202 includes two configurable inputs and outputs and supports optional 24 VDC backup power to maintain measurements in the controller and communication to Grundfos Connect and the Grundfos GO app.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"background:#E1E3E6;border-left:3px solid #B8BDC4;padding:8px 14px;font-size:11.5px;color:#4A4A4F;margin-top:14px;line-height:1.5\"\u003eGenuine Grundfos equipment, factory-new in original packaging — sold and supported by Watermain Supply, an independent industrial supplier.\u003c\/div\u003e\n\u003cdiv class=\"gs-sec\"\u003e\n\u003cdiv class=\"gs-h\"\u003eMain Features\u003c\/div\u003e\n\u003cdiv class=\"gs-lead\"\u003e\u003cul\u003e\n\u003cli\u003eCompatible with the full range of SQFlex pumps\u003c\/li\u003e\n\u003cli\u003eMultiple control modes\u003c\/li\u003e\n\u003cli\u003eIntuitive LED display and simple control, with dim \/ sleep mode on the display LEDs\u003c\/li\u003e\n\u003cli\u003eAdjustable maximum speed to match well yield, directly on the keypad\u003c\/li\u003e\n\u003cli\u003eWide voltage range — 30 to 300 VDC and 90 to 240 VAC\u003c\/li\u003e\n\u003cli\u003eReal-time clock — ready for scheduling\u003c\/li\u003e\n\u003cli\u003eSave \/ restore configuration\u003c\/li\u003e\n\u003cli\u003eAutomatically generated installation report\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"gs-sec\"\u003e\n\u003cdiv class=\"gs-h\"\u003eSpecifications\u003c\/div\u003e\n\u003cdiv class=\"table-wrapper\"\u003e\u003ctable class=\"gs-tbl\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eGrundfos designation\u003c\/td\u003e\n\u003ctd\u003eCU 202 UL 2 (also written CU202)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart No.\u003c\/td\u003e\n\u003ctd\u003e92799798\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication\u003c\/td\u003e\n\u003ctd\u003eMonitoring and control of SQFlex submersible pumps in solar applications\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupply voltage range\u003c\/td\u003e\n\u003ctd\u003e30 to 300 VDC and 90 to 240 VAC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePump communication\u003c\/td\u003e\n\u003ctd\u003eMains-borne signalling over the pump power supply cable — no extra cable to the pump\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLocal interface\u003c\/td\u003e\n\u003ctd\u003eKeypad and LED display: system status, alarms and warnings, pump performance data\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWireless\u003c\/td\u003e\n\u003ctd\u003eBuilt-in Bluetooth for Grundfos GO; Wi-Fi for Grundfos Connect\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWired communication\u003c\/td\u003e\n\u003ctd\u003eGENIbus, Modbus\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInputs and outputs\u003c\/td\u003e\n\u003ctd\u003eTwo configurable inputs and outputs — level or pressure signal for start and stop\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBackup power\u003c\/td\u003e\n\u003ctd\u003eOptional 24 VDC, keeps measurements and communication alive\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDefault configuration\u003c\/td\u003e\n\u003ctd\u003eTank filling\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003c\/div\u003e\n\u003cp style=\"font-size:12.5px;color:#9B9EA3;margin-top:8px;line-height:1.55\"\u003eFrom the Grundfos CU 202 datasheet 93298465, 11\/2024.

It is used wherever the system has a storage tank with a level switch, a pressure tank with a pressure switch, a well whose yield calls for a speed limit, or a need for status and alarms on site or remotely.\u003c\/p\u003e\n\u003cp\u003eThe CU 202 is the controller on the Grundfos 2026 renewables price list. Grundfos literature from 2021 shows the earlier CU 200 for pumps up to 1400 W and the CIU 903 for the 2500 W high-speed pumps; Grundfos states the CU 202 is compatible with the full SQFlex range. For Grundfos Connect, Grundfos calls for a 3-wire 18 AWG communication cable between the CU 202 and the CIU 902, and a Grundfos Connect subscription for each installation.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"gs-note\"\u003e\n\u003cb\u003eBefore You Order\u003c\/b\u003eThe part number is the control unit only: pump, array, disconnects, surge protection, level or pressure switch and cable are separate items.
