2.2 GRUNDFOS Control 2000 S Fig. 2 PFU 2000 Front Cover The GRUNDFOS Control 2000 S controls a number of pumps on mains operation. The Control 2000 S always includes the PFU 2000 with applica- tion-optimized software, but it is also available with a PMU 2000.
2.2.1 Examples of Booster Sets Hydro 2000 S Example: Example: GRUNDFOS Hydro 2000 MS. GRUNDFOS Hydro 2000 MSH. Four pumps and a diaphragm tank. One half-size pump, three full-size pumps and a diaphragm tank. PFU 2000 PFU 2000 One pump in operation.
Operation with PFU 2000 EPROM settings or PFU 2000 RAM settings can be changed by means of the DIP switches in the PFU 2000. 1. Connect the GRUNDFOS BUS between the PMU 2000 and the PFU 2000. The PFU 2000 EPROM default settings and the PFU 2000 RAM settings are listed in the “List of Control Parameters”.
The pumps are cut in if the actual value remains below the set- PMU 2000 point. With the “control function” (display 214) set to “normal”, the GRUNDFOS BUS switching-off levels for the cascade-controlled pumps are calcu- lated as follows: PFU 2000...

3.2.4 Setpoint 3.2.5 Setpoint Influences Operation with PFU 2000 RAM / PMU 2000 Settings: Operation with PFU 2000 RAM / PMU 2000 Settings: The maximum setpoint is set in “setpoint max.” (display 200). In order to optimize the operation of the system, it is often advan- This value is the upper limit of the setpoint and forms the basis of tageous to operate the system with a variable setpoint instead of the calculation of “setpoint act.”...
Remote Control of Setpoint via a PCU 2000: Via PCU 2000 inputs for the pumps connected to the zone and the GRUNDFOS BUS, the setpoint may be controlled linearly to the PCU 2000 input signal. Operation with PFU 2000 EPROM Settings:...
3.2.7 Measuring Unit for Control Value 3.2.9 Minimum Switching Sequence Operation with PFU 2000 RAM / PMU 2000 Settings: Minimum switching sequence is the time between two switchings (on/off of pumps). If the signal transmitter used features a measuring unit different from the one in the presetting, an alternative measuring unit can Operation with PFU 2000 RAM / PMU 2000 Settings: be selected (display 213).

Motors fitted with grease nipples should be lubricated with a high- temperature lithium-based grease, see the instructions on the fan cover of GRUNDFOS motors. In the case of seasonal operation (motor is idle for more than 6 months of the year), it is recommended to grease the motor when the pump is taken out of operation.
9. Operating and Fault Indications The two indicator lights (LED) on the front cover of PFU 2000/ PMU 2000 indicate pump operation (green) and/or fault (red). Two external indicator lights (LED) can be connected instead of the two indicator lights (LED) on the front cover. The function of the indicator lights (LED) and the operating and fault signal outputs appears from the table below.
