do you need the pressure switch connected or does it work without pressure switch like varistream

The controller will work if you bypass the pressure switch. However we designed the controller to operate with the pump pressure switch. for sound engineering reasons.
1. This provides an additional fail safe should for any reason the controller fail to (DE) stop the pump for some reason.
2. The controller carries out an electrical test to ensure the pump and pressure switch are in the circuit. If the pump can not detect the pump due to damaged cable/connectors the control will display PS (pressure switch) as a default message. This is one of the crucial protections we put in place. The control no longer passes any current to the pump but instead retests the condition every few seconds. This prevents a dangerous condition occurring for example ( a loose moving or damaged connection touching ground (Van panels) because the controller is now limiting the energy.
If you are planning to come to the Dorset Show Saturday I will be there and can discuss this further.
