Truma Ultraflow Smart Switch 2nd Generation

Upgrade your water system with the Truma Ultraflow Smart Switch 2nd Generation. This self-calibrating system is designed to intelligently manage the pressure-controlled Ultraflow Maxi Pump used in many caravans and motorhomes.

The inline adaptive technology constantly measures your submersible pump's performance and monitors battery voltage, automatically adjusting the start and stop pressures to ensure consistent and efficient water delivery. Thanks to the integrated processor, no adjustments are ever required—simply plug it in for optimal performance.

The Smart Switch includes crucial dry-run protection. If the water container runs empty, the system detects the lack of water and immediately stops the pump after a short delay, preventing costly damage. The pressure switch then locks out until the water tank is safely refilled.
