4. INSTALLATION AND SIZING CONSIDERATIONS
The Well-X1™functions like a traditional pressure switch by cycling the pump on and off. The factory pressure settings are 40 psi cut-in and 60 psi cut-out. The controller allows these settings to be adjusted to best suit the application. The Well-X1™can operate in two primary modes:
A. STANDARD OPERATION
Using a standard 20 psi differential, the Well-X1™can be sized according to the chart below. In this application, the sizing and performance will be similar to a traditional pressure tank and mechanical switch combination.

18 | WX1-251 | WX1-302 | WX1-302 | WX1-302 |
20 | WX1-302 | WX1-302 | WX1-302 | - |
B. CONSTANT PRESSURE MODE
The Well-X1™control allows a narrow differential to provide consistent water pressure. The factory 20 psi differential can be reduced so the cut-in and cut-out pressures are within 10 psi. When installed as a constant pressure system, the chart below should be used to ensure the tank volume is sufficient to provide adequate cycle protection.
