When the selection is confirmed, "Setting assistant" will be displayed in the menu.
Select a control mode via the
application and
system type.
All control modes
are also available to be selected
directly.
Direct selection of a basic control mode
In the "Settings" menu, select the following in turn:
1. "Set control mode"
2. "Setting assistant"

application.
The following basic control modes are available:
Basic control modes
‣ Differential pressure ∆p-v
Settings help
‣ Differential pressure ∆p-c
‣ Index circuit ∆p-c
‣ Dynamic Adapt plus
‣ Volume flow Q-const
‣ Multi-Flow Adaptation
‣ Temperature T-const.
‣ Temperature ∆T-const
‣ Speed n-const
‣ PID control
Table 21: Basic control modes
Every control mode, with the exception of speed n-const, additionally requires the selection
of the actual value or sensor source (analogue input AI1 ... AI4).
When you confirm a selected basic control mode, the "Setting assistant" sub-menu appears,
displaying the selected control mode in the information bar.
You see more menus under the display. These are intended for parameter configuration.
For example: input of the setpoints for differential pressure control, activation/deactivation
of the "No-Flow Stop" function or input of emergency operation speed.
NOTICE
The differential pressure sensor of the Stratos GIGA2.0-I/-D is already
configured at the factory to 2 ... 10 V at the analogue input.
No other setting of the analogue input is required for a control mode with
differential pressure (Dynamic Adapt plus, Δp‑v, Δp‑c) and volume flow
constant (Q-const.).
If the analogue input has not been configured at the factory or if the signal
2 ... 10 V or 4 ... 20 mA is not recognised, the "Cable break in analogue 1"
warning is displayed
For the Stratos GIGA2.0-I/-D ... R1, no analogue input is configured at the
factory. The analogue input must be actively configured for every control
mode.
If no analogue input is configured for a control mode with differential
pressure (Dynamic Adapt plus, Δp‑v, Δp‑c) and volume flow constant (Q-
const.), the warning "Delivery head/flow unknown" (W657) is displayed.
NOTICE
For the Stratos GIGA2.0, the differential pressure sensor is already pre-
configured to an analogue input at the factory. For Stratos GIGA2.0 ... R1,
no analogue input is preconfigured yet.
