SQFlex Controllers

Control Unit - the "brain" of the system lets you specify your preferred water pressure, make manual

 adjustments for special needs, and tells you when the system is boosting pressure. All with a simple, user-friendly design!

IO 100 / IO 102

IO 100
A very simple and easy-to-use system and with cable interface. Controlled by a manual on/off switch.
IO 101
Acts as interface for powering back-up supplies, providing automatic change-over. For instance when changing from generator to solar energy, the solar panels automatically power the system as soon as the fuel tank runs dry.

CU 200

A user-friendly interface box that maintains two-way communication with the pump

 and monitors the operating conditions. Built-in diagnostics indicate faults and dry-running, display operating status power consumption and level switch input.

SQFlex Water Level Switch

 Level Switch

Save energy as you save water. With a level switch inside the storage tank connected to the CU 200 control unit, the pump knows when the tank is full and shuts itself off.
