ARP Circulation Pump
Application
-The ARP circulation pump is used for transferring clean water or other liquids similar to water in physical and chemical properties
-Heating systems with constant or variable flows
-Heating systems with variable flow-pipe temperature
-Heating systems where night setback is desired
-Heating systems where the differential pressure of the pump is too high during periods of reduced flow demand
-Heating systems that require a fully automatic adjustment of the performance to flow demands
-Pressure boosting of water heaters
-Circulation and pressure boosting of domestic water

| Mode | Pump Feature | Function |
| Auto | Max.to min. proportional pressure curve | The automatic adaptation function allows the pump to control the performance to within a defined performance range (i.e. adjusting the pump performance to the system size and the variations in load over time). In this mode, the pump is set to proportional-pressure control |
| PP1 | Min. Proportion pressure curve | The pump duty point will move up or down on the lowest proportional pressure curve, depending on the heat demands in the system. The pressure is reduced when the heat demand falls, and increases when the demand rises |
| PP2 | Max. Proportion pressure curve | The duty point of the pump will move up or down on the highest proportional pressure curve, depending on the heating demand in the system. The pressure is reduced when the heat demand falls, and increases when demand rises |
| CP1 | Max. constant pressure curve | The duty point of the pump will move out or in on the highest constant-pressure curve, depending on the heat demand in the system. The pressure is kept constant, regardless of the heat demand. |
| CP2 | Min. constant pressure curve | The duty point of the pump will move out or in on the highest constant-pressure curve, depending on the heat demand in the system. The pressure is kept constant, regardless of the heat demand. |
| Ⅲ | Speed Ⅲ | In speed Ⅲ, the pump is set to run on the maximum curve under all operating conditions. Quick venting of the pump can be obtained by setting the pump to speed Ⅲ for a short period. |
| Ⅱ | Speed Ⅱ | In Speed Ⅱ, the pump is set to run on the intermediate curve under all operating conditions. |
| Ⅰ | Speed Ⅰ | In Speed Ⅰ, the pump is set to run on the min, curve under all operating conditions. |
| Night mode | The pump changes to automatic night setback, (the minimum performance and power consumption) provided that certain conditions are met. |
