2000h - Pump Setpoint

This Parameter sets the active working point of the pump. The resolution is in 0.01 Percent which means that the value 10000 corresponds to 100%. 100% represents the max setpoint (depending on Control Mode, Max Pressure, Max Speed, etc.) and 0% represents the setpoint 0 (not depending on control Mode).

If a value is written that is lower than the specified pump min value (depending on Control Mode) it is limited to the min value and the Par 2050h Bit 2 - Setpoint out of Range is set. The pump does not turn off if the value 0 is written.

The setpoint is saved internally on power off. If the pump is restarted or rebooted the last value is loaded automatically.

Usage: This value should not be automatically written, it should only be written if a change is required (a user manually changes the setpoint on a monitor or alike) otherwise it will take priority over other control methods, and would make it impossible to change the Setpoint from other sources. If an automated source is to set Values, then use Par 2008h - Bus Setpoint instead of this Parameter.

Note: This Parameter is write only, in order to read back the setpoint that is being processed by the pump, read Par 2048h - Wanted Setpoint.

Dependency: This Parameter can change meaning if Par 2041h - System Control Mode changes.

Dependency: This Parameter is disabled, if the Par 200Ah Bit 5 - Activate Bus Setpoint is set to "1".

Dependency: CAN write access to This Parameter is disabled, if the Par 2056h Bit 4 - Local Operation Active is set to "1".

In the case of a Single Pump, This Parameter contains/affects the value of This Pump.
In the case of a Double Pump - Master, This Parameter contains/affects the value of This System.

2001h - Pump Control Mode

This Parameter sets the active control mode of the pump. It is basically the same as the Par 2009h - Bus Control Mode. If a Control Mode is to be set in the pump, this parameter should be used. This Parameter has no constant min and max values, instead it allows only the supported Control Modes to be written to This Parameter. If a value is written, that is not supported, a min, max or other suitable error will be generated by the pump and the last valid value will be kept.

If CONST_SPEED mode is set in a DP System, both pumps run syncronously. CONST_SPEED mode is not supported by this parameter if the active pump is in a MP system.

The control mode is saved internally on power off. If the pump is restarted or rebooted the last value is loaded automatically.

Usage: This value should not be automatically written, it should only be written if a change is required (a user manually changes the setpoint on a monitor or alike) otherwise it will take priority over other control methods, and would make it impossible to change the Control Mode from other sources. If an automated source is to set values, then use Par 2009h - Bus Control Mode instead of this Parameter. This value does not affect the value of Par 2000h - Pump Setpoint (or Par 2008h - Bus Setpoint) and Par 2048h - Wanted Setpoint (if they already were at 50% they stay at 50% after changing this Parameter).

Note: This Parameter is write only, in order to read back the chosen setpoint for the pump, read Par 2049h - Wanted Control Mode.

Dependency: This Parameter is disabled, if the Par 200Ah Bit 6 - Activate Bus Control Mode is set to "1".

Dependency: CAN write access to This Parameter is disabled, if the Par 2056h Bit 4 - Local Operation Active is set to "1".

Dependency: This Parameter disables Par 208Bh - Estimated Pressure (System), if it is set to "CONST_CONTROL (PID)".

In the case of a Single Pump, This Parameter contains/affects the value of This Pump.
In the case of a Double Pump - Master, This Parameter contains/affects the value of This System.

2002h - Pump Command

This Parameter controls the running mode of the pump.

Usage: This value should not be automatically written, it should only be written if a change is required (a user manually changes the setpoint on a monitor or alike) otherwise it will take priority over other control methods, and would make it impossible to turn the pump on or off from other sources. If an automated source is to set values, then use Par 200Ah - Bus Command instead of this Parameter.

Dependency: This Parameter is disabled, if the Par 200Ah Bit 5 - Activate Bus Setpoint is set to "1".

Dependency: CAN write access to This Parameter is disabled, if the Par 2056h Bit 4 - Local Operation Active is set to "1".

In the case of a Single Pump,
In the case of a Double Pump - Master,

2002h Bit 0 - Pump On/Off

This Bit turns the pump on or off. On means that the pump is pumping and Off means that the pump is not pumping. It is not possible to completely turn off the pump, the pump is always in standby mode.

Note: The on off setting is saved internally on power off, this parameter becomes this saved value upon restart or reboot.

Dependency: This Bit has the same priority as Par 200Ah Bit 0 - Pump On/Off.

Dependency: This Bit has lower priority than Par 200Ah Bit 1 - Extern Off.

Dependency: This Bit has lower priority than Par 200Ah Bit 2 - Extern Max.

Dependency: This Bit has lower priority than Par 200Ah Bit 3 - Extern Min.

Dependency: This Bit has lower priority than Par 200Ah Bit 4 - Extern On.

In the case of a Single Pump, This Bit contains/affects the value of This Pump.
In the case of a Double Pump - Master, This Bit contains/affects the value of This System.

2008h - Bus Setpoint

This Parameter sets the active working point of the pump.

Usage: This value should only be used if a source continuosly sends values (a regulation unit, a 0-10V conversion unit or similar). If only a new value is to be written, then use Par 2000h - Pump Setpoint.

Note: If the setpoint is accompanied with a control mode (PDO), and the control mode is invalid, only the setpoint will be accepted and it would then depend on the previously selected control mode.

Note: This Parameter is write only, in order to read back the setpoint that is being processed by the pump, read Par 2048h - Wanted Setpoint.

Note: All percentages lower than the current min value (depending on Control Mode) are accepted, but limits the value to the min value. This activates the Par 2050h Bit 2 - Setpoint out of Range. The pump does not turn off if the value 0 is written to This Parameter.

Note: This Subindex is reserved for I/O-Module or Bus communication, it should not be used by a Gateway or other Master device.

Note: In the case of a DP or multipump where one or more pumps are set to Off, Max, Min or On, the other (DP), or one of the others (MP), still regulates with the chosen setpoint (This Parameter). This means that an external regulation unit can set specific pumps to Off, Max, Min or On (with specified fixed speed) and still regulate the last pump externally.

Dependency: This Parameter can change meaning if Par 2041h - System Control Mode changes.

Dependency: This Parameter is disabled, if the Par 200Ah Bit 5 - Activate Bus Setpoint is set to "0".

Dependency: CAN write access to This Parameter is disabled, if the Par 2056h Bit 4 - Local Operation Active is set to "1".

In the case of a Single Pump, This Parameter contains/affects the value of This Pump.
In the case of a Double Pump - Master, This Parameter contains/affects the value of This System.

2009h - Bus Control Mode

This Parameter is basically the same as the Par 2001h - Pump Control Mode. The difference is that this parameter is written by a I/O-Module and it can have a higher priority (set by Par 200Ah Bit 6 - Activate Bus Control Mode) than its counterpart. It sets the active control mode of the pump.

Usage: This value should only be used if a source continuosly sends values (a regulation unit, a 0-10V conversion unit or similar). If only a new value is to be written, then use Par 2001h - Pump Control Mode.

Note: This Parameter is write only, in order to read back the chosen setpoint for the pump, read Par 2049h - Wanted Control Mode.

Note: This Parameter has no constant min and max values, instead it allows only the supported Control Modes to be written to This Parameter. If a value is written, that is not supported, a min, max or other suitable error will be generated by the pump.

Note: This Parameter is reserved for I/O-Module or Bus communication, it should not be used by a Gateway or other Master device.

Note: If CONST_SPEED mode is set in a DP System, both pumps run syncronously.

Note: CONST_SPEED mode is only supported by this parameter if the active pump is in a MP system. The MP CONST_SPEED mode is very different from the DP speed mode.

Dependency: This Parameter is disabled, if the Par 200Ah Bit 6 - Activate Bus Control Mode is set to "0".

Dependency: CAN write access to This Parameter is disabled, if the Par 2056h Bit 4 - Local Operation Active is set to "1".

Dependency: This Parameter disables Par 208Bh - Estimated Pressure (System), if it is set to "CONST_CONTROL (PID)".

In the case of a Single Pump, This Parameter contains/affects the value of This Pump.
In the case of a Double Pump - Master, This Parameter contains/affects the value of This System.

200Ah - Bus Command

Note: This Parameter is write only, in order to read back the chosen setpoint for the pump, some of the values can be read in Par 204Ah - Wanted Command.

Note: This Parameter is reserved for I/O-Module or Bus communication, it should not be used by a Gateway or other Master device.

Note: The activation bits are always evaluated first, so this byte can contain an combination of different values.

Note: This Parameter is deactivated if Par 1016h Sub 1 - Consumer Heartbeat Time (I/O Module) is activated and no corresponding heartbeat is present on the bus.

Example: If Par 200Ah Bit 2 - Extern Max is set in an MP system, then all pumps would run at Maximum Speed. If Par 2021h Sub 2 - Extern Off (Slave 1) is set at the same time, all pumps would run at Maximum Speed, but Slave 2, since Extern Off has higher Priority than Extern Max, would be turned off.

Dependency: CAN write access to This Parameter is disabled, if the Par 2056h Bit 4 - Local Operation Active is set to "1".

In the case of a Single Pump,
In the case of a Double Pump - Master,
