3. Activate parameter 3-5-4 (charging accumulator).
4. Set parameter 3-11-1 (energy-saving mode) to ON.
5. Set parameter 3-11-2 (direct OFF) to ON.
The setting OFF
(flow detection) should only be selected for difficult site conditions and
6. Enter the pump load value in parameter 3-11-3 (stop speed %).
7. Set parameter 3-11-4 (time Direct OFF) to define the time period the pump is to keep on
running in order to charge the accumulator before stopping.
8. Adjust parameters 3-11-3 and 3-11-4 until the required stopping behaviour is obtained.

7.1.14 Setting flow detection
When one pump set is operated, the control unit checks the quantity of the fluid handled.
The pump set’s speed is slightly lowered within a configurable time interval. If the actual
value is within the bandwidth, the control unit triggers the filling of the accumulator and stops
the pump set.
Setting the time interval
ü
Logged in at Service level.
1. Call up parameter 3-4-3-5-2 (time flow rate).
2. Set time [seconds].
Setting the bandwidth
ü
Logged in at Service level.
1. Call up parameter 3-4-3-5-1 (bandwidth flow rate).
2. Set the setpoint [%].
7.1.15 Setting the ambient temperature monitoring device (optional)
If the configurable ambient temperature value is exceeded, a warning message is output.
The ambient temperature is shown on the display. When the 24-hour average ambient
temperature is too high, an alert (red LED) is output. Ambient temperature monitoring cannot
be used in combination with the digital inputs for remote reset, setpoint changeover and
functional check run.
ü
The temperature sensor Pt1000 is fitted and electrically connected.
[
1. Call up parameter 3-3-4 (WSD).
2. Set the water flow detection on the accumulator to TEMPERATURE.
3. Call up parameter 3-4-4-3 (ambient temperature).
4. Set the temperature [°C].
7.1.16 Enabling digital inputs (optional)
NOTE
This function cannot be used in conjunction with ambient temperature
monitoring.
