UPS3 is a circulator pump designed to be used in domestic heating systems with either variable or constant flow rate. The pump automatically controls the differential pressure by adjusting the pump performance to the actual heating demand without the use of external components. <P><P> The new UPS3 is a compact, high efficiency replacement for Grundfos UPS and UPS2 15-50/60 circulator pumps and many internal boiler pumps. Suitable for domestic heating systems with boilers up to 30kW, just one model of UPS3 can be used to replace all previous 4m, 5m and 6m head versions of UPS and UPS2 pumps. <P><P> <strong> Features & Benefits: </strong> <br> </p><ul> <li> Three constant curves/constant speed curves.</li> <li> Two proportional-pressure curves.</li> <li> Two constant-pressure curves.</li> <li> Speed control via a low-voltage PWM (Pulse Width Modulation) signal profile A (heating). The PWM signal is a method for generating an analog signal using a digital source.</li> <li> Low EEI (Energy Efficiency Index).</li> <li> Deblocking device.</li> <li> Alarm and warning indication.</li> <li> Low noise level.</li> <li> Very simple installation.</li> </ul>
