I have just installed a PS150 BOOST pump and PUMPROL points and a PS Controller unit in a Solar array. Cut in cut out pressure is 30/50PSI, this is all working fine the pump is cutting in at the required pressure and cutting out at the required pressure but when the pump cuts out and the points open it shows a red LED on the PS contoller say Tank Full(which is not possible as there is no float switch installed at this stage). When the pressure is dropped to the 30PSI the contact points close to start the pump but it will not kick back in and still has the Tank Full Red LED showing?
Any help I would be very grateful

Cheers
