Selection of secondary pumps for Multi-Flow Adaptation
Select the partner pump by turning the operating button and press to confirm.
When pressed, the white tick appears on the selected pump.
The secondary pump indicates for its part on the display that it has been selected.
All other secondary pumps are selected in the same way. Then press the Back button to go back to the "Set
control mode" menu.
When secondary pumps are installed in a circuit with a mixer, the mixed volume flow can be taken into ac-
count. For this purpose, select and activate the additional control function Multi-Flow Adaptation mixer.
Set control mode: Multi-Flow Adaptation mixer
To be able to use the function, the temperatures on the feeder pump have to be recorded:
• in the secondary feed (T1) downstream of the hydraulic shunt
• in the primary feed (T2) upstream of the hydraulic shunt
For this purpose, connect temperature sensors to the AI1 and AI2 analog inputs.
NOTICE
In order to determine the mixed volume flow, the heat quantity measurement function with
a connected temperature sensor in the secondary feed and secondary return must always be
activated on the secondary pumps with mixer.
Select "Switched on" by turning the operating button and press to confirm.
The temperature sensors on the feeder pump must then be configured on the AI1 and AI2 analog inputs. To
do this, select the temperature sensor T1 for the temperature of the secondary feed in the "Set control
mode" menu.
In this way, the analog input AI1 is automatically configured to signal type PT1000 and used as the actual
temperature value T1.
Proceed in the same way with the temperature sensor T2 on analog input AI2.
After these adjustments, Multi-Flow Adaptation is activated with the additional control function "Multi-Flow
Adaptation mixer".
9.6 Adjustment - Manual operation
All control modes, which are selected via the setting assistant, can be overridden with the functions of man-
ual operation OFF, MIN, MAX, MANUAL.
DANGER
The pump can start despite the "OFF" function
The "OFF" function is not a safety function and is no replacement for disconnecting the
power supply for maintenance work. Functions such as pump kick can start up the pump de-
spite the "OFF" function being set.
• Always disconnect the pump from the power supply before carrying out any work!
Manual operation functions can be selected in the menu
"Manual operation (OFF, MIN, MAX, MANUAL)":
