Thanks Ian.....
Struggled a bit this morning again too...I tried auto cal and it just kept coming up ERR...
Same thing the pump either DE or PS with cycling in between....no continuous flow...finally got it to pump continuously by flow on 46 and CAL on 99(reduced down to 45 once my water was hot)....
Could the pressure switch be faulty?
Once I got it going its been great all day..it dead ends quickly after turning tap off at pole even with very hot water
Hi Dazmond
While PS is displayed the controller will struggle to auto cal this is because the pump is not running. so there is nothing for the controller to detect. A high calibration figure does make it more likely the Pump pressure switch will activate rather than being dead ended by the controller.
The cycling between DE/PS was likely due to the High calibration as the pump pressure would activate on occasion because the controller would be slow to DE at a high Cal value.
Once there was consistent flow at 46 and Cal 45 the controller was working as expected.
As this is a hot system hoses will expand more once there are warm and you may find cal can come down a little more as this will make the controller quicker to DE the pump. A suggestion here is to run auto cal with flow rate set at 46 with the hoses cold.
The reason for doing it with hoses cold is that sets the maximum end of Calibration for the system as the Hoses warm and expand Calibration would be lower. By setting the Cal with cold hoses we give the system some flexibility.
Note the discussion around resin beads. It is a possible cause of pump problems as the beads can block the pump head vane in worst case scenario. That said at the moment as the controller has found the right cal for the flow rate and set that seen im leaning more toward it being a case of setting up with the new pump.
Re a faulty pressure switch its possible you have been unlucky, But again as the system has found its sweetspot that seems unlikely. Have good Christmas/New year Break
