Hi, I have a Grundfos JQ1 pump that according to the suppliers needs a new pressure switch (Transducer).
The pump won't start and gives 6 flashes on the red led on the control panel. I have also been told that the switch is no longer available.
Does anyone know of any old stock. Alternatively, can this pump be modified to run continuously and use and external sensor.
I have a reasonable knowledge of electronics so any info such as a circuit diagram or service manual would be much appreciated.
