Page 12: Operating Modes
8. Operating modes User operation depends on the system mode. The system modes are described in the following sections. 8.1 Local mode, external stop not activated In this mode, the system is locally controlled, and the external stop via digital input is not activated. The flow charts below show examples of how settings can be made. -

Changing the setpoint Changing the setpoint If you do not touch the buttons for 3 seconds, CU 323 reverts to the initial display. 8.2 Remote-controlled, external stop not activated In this mode, the system is remote-controlled, and the external stop via digital input is not activated. If you want to change the local settings, follow the flow chart examples below. -

8.4 Adjusting the proportional-pressure setpoint The function has these purposes: • compensate for pressure losses Description • reduce the energy consumption You can only enable this function in pressure-controlled systems. • increase the comfort for the user. The function automatically adapts the setpoint to the actual flow rate to compensate for flow-dependent dynamic losses. -
