Features
The WellZone™ digital controller provides pressure control for single phase 2-wire submersible well pump applications. It uses a 0-150 PSI pressure transducer to monitor the discharge pressure and turns the pump ON and OFF according to the Start and Stop setpoints. The LCD display is visible through the clear cover of the enclosure to allow for quick view of the system pressure, run status, hours run and pump cycles. The rotary button provides the user with a simple navigation method through the menu and program settings. It features built in pump protection including rapid cycling and dry run. It is preprogrammed to run the pump as the pressure drops below 40 PSI and stop as the pressure rises above 60 PSI. High & Low pressure settings are available with an auxiliary alarm relay.
Mounting the Control Panel
- Drill and fasten top of the enclosure using appropriate anchor.
- Drill and fasten bottom of the enclosure using appropriate anchors.

Wiring the Control Panel
CAUTION!
Disconnect all power to the control panel before wiring.
Ensure that the incoming supply power voltage is the same as the rating of the pump motor being installed. Ensure that the rated Amps of the motor does not exceed the rating of the control panel.
- Connect the following wires to the proper terminal positions:
• Incoming power to the circuit breaker
• Motor/Pump power to Motor
• Pressure transducer
See wiring label on inside the control panel for details. - Verify correct operation of control panel after the installation is complete.
- Maximum motor cable lengths.
| Motor | Feet – Motor Cable (75C)¹ | |||
| Vac | HP | Amps² | 14 AWG | 12 AWG |
| 115V | 1/2HP | 12.0A | 100 | 160 |

¹Cable length is measured from the motor to the main panelboard (Service Entrance) 75C Insulation – AWG Copper Wire only. Do not use aluminum conductors.
Use with 2-wire motor only with internal thermal protection.
²Typical S.F.A. (Service Factor Amps). Check motor nameplate for actual data.
Operation Guide
Notes :
A. If there is no operation for 20 sec, the display will return to the main screen.
B. The service function is used for alerting the user when it is time to change a filter or to serivce the equipment after the accumulated run time is reached.
The icon 
will flash on main screen when the timer is done (Filter at 0%).
Push and hold ESC button 4 seconds to reset the filter or service time.
| Parameter | Description | Default | Range Min | Range Max | Unit | Function |
| START | Start Pressure | 40.0 | 1.0 | 140.0 | PSI | The pump will RUN when the pressure drops below the “START” pressure value and continue to RUN until the pressure rises above the “STOP” value. Set START<STOP. The “STOP” value should be at least 10 PSI over the “START” value. |
| STOP | Stop Pressure | 60.0 | 10.0 | 150.0 | PSI | The pump will RUN when the pressure drops below the “START” pressure value and continue to RUN until the pressure rises above the “STOP” value. |
| HIGH | High Pressure | 70.0 | 0.0 | 150.0 | PSI | High Pressure alarm. The pump will stop if the pressure rises above this value. |
| LOW | Low Pressure | 20.0 | 0.0 | 150.0 | PSI | Low Pressure alarm. If the pressure drops below this value, the “LOW TMR” timer will start. The pump will stop when the timer is done and a “LOW PRESS” alarm will be displayed. |
| LOW TMR | Low Pressure Timer | 30 | 0 | 3599s(59m:59s) | Seconds | Low pressure timer. This delay timer needs to be long enough to allow the pump to pressurize the system on start up. It can be used to detect a broken discharge pipe or significant leak. Value is in Seconds (s). |
| OVERLOAD | Motor Overload | 12.0 | 4.0 | 14.0 | Amps | Set to the motor S.F.A. (Service Factor Amps) value as listed on the motor nameplate. The pump will stop if it is pulling excessive amps and the “OVERLOAD” alarm will be displayed. The controller will reset the fault automatically after a cooling period. The controller will reset this fault 4 times automatically before requiring a manual reset. |
| DRY RUN | Dry Run Amps | 0.0 | 0.0 | 14.0 | Amps | Pump DRY RUN protection. Set this value lower than the normal pump operating amps. 30% lower than the motor Service Factor Amps is common. Adjust up or down as this function is tested. Example: Motor SFA = 10.0A. Set the Dry Run Amps = 7.0A. Set to “0.0” to disable this function (Default). |
| DRY TMR | Dry Run Timer | 30 | 0 | 3599s(59m:59s) | Seconds | Time delay before stopping the pump on “DRY RUN” as the amps are lower than the “DRY RUN” amps value. Timer value is in seconds (s). |
| RECHARGE | Recharge Timer | 20 | 0 | 3599m(59h:59m) | Minutes | Automatic reset timer after a “DRY RUN” trip, allowing for enough time for the well to recharge. Timer value is in minutes (m). |
| STRT / MIN | Starts Per Minute | 2 | 1 | 10 | Cycles | Rapid cycle protection. Enter the maximum allowable pump starts per minute. If the number of starts is exceeded, the display will show “RPD CYCL” and a manual reset is required for the pump to start again. |
| NO AMPS | No Amps Detect | ON | ON | OFF | NA | No amps detection function informs the user of thermal switch trip internal to the motor. Allow the motor to cool and it will start again automatically. This detection function is disabled when set to “OFF”. |
| FILTER | Filter Life Timer | 200 | 1 | 9999 | Hours | Set the estimated pump run time between filter replacements. The time is set in hours (h) and corresponds to pump running hours. will flash on the screen when this timer is done. |
Fault Information
Auto Reset – resets when the fault clears
Manual Reset – press and hold ESC button over 4 seconds in main screen.
