A controller for large pumps with motor power from 1.1kW to 2.2kW. The Watertech Controlpres is an automatic controller which allows the setting of the working pressure. The Controller will start and stop the pump depending on opening and closing of the taps and offers run dry protection. It comes equipped with automatic restart in case of failure and anti-jamming function. Ideal for above ground pumps and submersible pumps up to 3 HP. The working pressure and start pressure are adjusted by turning the knob on the back of the device. Technical Information Operation Parameters Adjustable start and output pressure Run Dry Protection A user-friendly interface with LED indicators displaying power status, pump running and alarm indication. 1”1/4 (32mm) male connections to guarantee a higher flow rate Pressure Gauge No need for an expansion tank, check valve, filter or fittings. Starting Pressure 1.2–4.5 Bar Output Pressure 3–6.5 Bar Technical Features Power: 1.1kW (1.5 HP) -115V - 2.2kW (3 HP) - 230V Pressure regulating range: 3 – 6.5 bar Max Current: 16A Max Operating Pressure: 12 Bar Single Phase-115/230 Frequency: 50-60 Hz Protection Grade: IP65 Max Temperature: 65°C Minimum Flow Rate-1 LPM Certifications: TÜV SÜD 1 Year Manufacturing Defect Warranty View our Warranty Terms here. Construction Materials Wetted parts are made from high quality corrosion resistant materials Installation and Startup The device can be installed directly on the pump or between the pump and the first tap. Make all the electrical connections, check that the pump is correctly primed, open a tap and energize. The green Power on led will light up on the control panel and the pump will start (yellow “Pump on” led on) and will keep running for several seconds to pressurize the system. If this time is insufficient, the device will stop the pump (red “Failure” led blinking). Press and hold down the Restart button until the red Failure led turns off and the water comes out of the open tap. When the tap is closed, the pump will stop after a few seconds (yellow “Pump on” led turns off). From now on, the device will turn the pump on and off depending on the opening and closing of the tap. To set the required pressure turn the knob on the back of the device (regulation range from 3 to 6,5 bar). In case of water shortage, the device will stop the pump and protect it from dry running (red “Failure” led blinking). In case of a temporary blackout, the device will automatically rearm once the electricity returns. Automatic Restart and Anti-Jamming Function In case of stopping due to a water shortage, the device will automatically make 10 double attempts to rearm over the 24 hours following the failure, each lasting approximately 5 seconds to allow the pump and the system to reload if possible. The user can try to rearm the device at any time by pressing the Restart button. If for any reason the pump remains idle for 24 consecutive hours, the device will carry out a start-up of the pump motor for about 5 seconds.
