By adjusting the motor/pump speed, the SubDrive Utility can deliver constant pressure dependably, even as water demand changes. For example, a small demand on the system, such as a bathroom faucet, results in the motor/pump running at a relatively low speed. As greater demands are placed on the system, such as opening additional faucets or using appliances, the speed increases accordingly to maintain the desired system pressure. Using the provided SubDrive pressure sensor, system pressure can be set in the range of 25–80 psi (1.7–5.5 bar). • Reduced Tank Size: Conventional systems use larger tanks in order to store water, whereas SubDrive Utility systems may utilize a smaller tank in order to maintain constant pressure. • Over Temperature Foldback: SubDrive Utility controllers are designed for full power operation in ambient temperatures up to 122 °F (50 °C) at nominal input voltage. In extreme thermal conditions, the controller will reduce output power in an attempt to avoid shutdown and potential damage while still trying to provide water. Full output power is restored when the internal controller temperature cools to a safe level. • Motor Soft Start: Normally, when there is a demand for water, the SubDrive Utility will be operating to accurately maintain system pressure. Whenever the SubDrive Utility detects that water is being used, the controller always “ramps up” the motor speed while gradually increasing voltage, resulting in a cooler motor and lower start-up current compared to conventional water systems. In those cases where the demand for water is small, the system may cycle on and off at low speed. Due to the controller’s soft-start feature and the sensor’s robust design, this will not harm the motor or the pressure sensor.Adjustable • Under-load Sensitivity: The SubDrive Utility controller is configured at the factory to ensure detection of under-load faults in a wide variety of pumping applications. In rare cases (as with certain pumps in shallow wells), this trip level may result in nuisance faults. If the pump is installed in a shallow well, activate the controller and observe system behavior. Once the controller begins to regulate pressure, check operation at several flow rates to make sure the default sensitivity does not induce nuisance under-load trips.
