The Submatic Q is a compact electronic pump controller designed for probe-level operation and automatic pump management. Built to work with two probe sensors (Probe N), it provides reliable water level regulation, dry-run protection and alarm output for a single pump application. The unit is available for 230V / 415V supplies and is specified to control motors up to 2 HP, making it suitable for sump pumps, sewage pumps, rainwater harvesting, tank filling and booster applications.

Key features

• Probe-based level control — accepts two probe inputs for filling or emptying without float switches.
• Dry-run protection to prevent motor damage and extend pump life.
• Relay outputs: motor control relay (suitable for up to 2 HP motors) plus a secondary relay for alarm or solenoid valves.
• Auto/Manual switch and input for a start/stop pressure switch or float switch for flexible control schemes.
• Compact, robust enclosure for easy integration in pump control panels and field installations.

Applications & compatibility

Ideal for domestic and light-commercial drainage and sewage systems, irrigation and rainwater harvesting, the Submatic Q pairs with Probe N sensor cables (available in multiple lengths) and can be used alongside pressure switches and float sensors for hybrid control setups. This makes it a versatile water level regulator and submersible pump controller for maintenance-free automatic operation.
