Fig. 86 Min., max. and user-defined duty
Description
The function allows you to let the pumps run in open loop at a set
performance.
Setting range
CU 352 allows you to change between three operating modes:
1. 8.7.39 Min. duty (4.3.14.1).
2. 8.7.40 Max. duty (4.3.14.2).
3. 8.7.41 User-defined duty (4.3.14.3).
For each of these operating modes, you can set the
number of operating pumps and the pump
performance (speed).
