Breaker box for SQFlex Wind, which are controlled by a manual on/off switch. Grundfos Remote Management The CiU 273 SQFlex is designed to work with the SQFlex pump and is a combined monitoring, control and communication unit for the SQFlex pump. CiU 273 enables monitoring the system operation anywhere in the world through GSM network. Grundfos SQFlex CU200 Interface Box Pump Controller. The CU200 interface box communicates with the pump and monitors operating conditions. Built-in diagnostics indicate faults and dry-running, display operating status, power consumption and water level switch input. Grundfos CU 200 SQFlex Control Unit A user-friendly interface box that maintains two-way communication with the pump and monitors the operating conditions. Built-in diagnostics indicate faults and dry-running, display operating status power consumption and level switch input. Grundfos has developed the MGFlex motor for optimal performance using solar power, for surface pump applications. In addition to solar panels, Grundfos solar surface pumps can be run from the grid or a generator. With variable speed operation and motor protection built in as standard, Grundfos solar surface pumps offer. Easy installation.

Grundfos Cu 200 Sqflex User Manual F3 Error 1

  The control box has an F3 where the volts are usually at. I don't know what that means, or how to fix it.

  
  Welcome to the forum.
  According to Grundfos, 'F3' means no contact to the pump. Hopefully that is just a bad connection or bad cable. In addition to checking the cable and the connection in the CU200, check the end cover (with socket) on the pump. The F3 fault could also mean a defective CU200 or defective pump.

  IS THERE ANY WAY TO BYPASS THE CONTROLER BOX

  
  I believe so (but have no actual experience with that pump or controller). One thing a controller does is protect the pump from running when the voltage or current is not sufficient.... the pump can be burned out if the voltage or current is not sufficient. If you are sure of your power source, you can give it a try. If a cloud comes by and drops your solar output, you may damage your pump.

  The Grundfos SQLFlex takes a wide range of AC or DC input because it uses a rectifier to get DC and then uses that DC to power an inverter that delivers exactly what voltage and frequency the pump motor needs to use up the available power.
  I do not think that the inverter is in the pump (I may be wrong), but rather in the controller. That means that bypassing the controller is very likely to damage the pump beyond repair, as the pump would want to run on correctly pulsed AC.

  The SQF Package has a standard SQ pump inside that runs from AC only. The majority of SQ pumps are 240vac. The SQ pump does have electronics inside for soft starting and detecting that water is there. A few other things also. If this was bought as a package the SQF, then you can feed 240 in to test it without the SQF electronics (you need to disconnect them!!!). The other thing is your well could be dry.

  11 days and he is not back and maybe he called the folks that installed the pump. Maybe he did what alot of people in my state are doing and called a water truck.....
  The problems I have seen with this controller were from lightning. Another good reason to run a straight type SQ pump at 240VAC or the shallow 120VAC SQ pump.

  Hi Don,
  We did fine this winter with a last rain in May topping off our 16,000 gallon tanks. The rainfall was about our lowest as we get between 30 and 60 inches a year. After 4 years of drought we had a seasonal total of 15 inches of rain and 1/2 inch of snow.
  There is a hurricane heading off the Baja coast that could bring us a shower if we are lucky. You never stop learning and we discovered that there can be 35 gallons in the roof to tank pipes that can condense off the roof some nights up here. We would hear it in the downspout for years. Last year we started saving the first 15 minutes of rainfall in a garden only tank and it really was an eyeopener.
  The state is giving people a tank and 2,500 gallons a month and helping with re-drilling for folks. I like the rainwater much more and it always tastes great to drink. It makes great ice cubes for adult beverages.....
  You take care and say Hi to Karen !
