Installation and operating instructions Wilo-Stratos GIGA2.0-I, Wilo-Stratos GIGA2.0-D
Setting the control functions
Basic control modes
‣ 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 se-
lection of the actual value or sensor source (analogue input AI1 ... AI4).
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
configured yet.
When you confirm a selected basic control mode, the "Setting assistant" sub-menu ap-
pears, 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/deactiv-
ation of the "No-Flow Stop" function or input of emergency operation speed.
Heating & cooling application
The "Heating & cooling" application combines both the applications if both heating and
cooling occurs in the same hydraulic circuit. The pump is set separately for both applic-
ations and can switch between both applications.
In the "Settings" menu , select the following in turn:
1. "Set control mode"
2. "Setting assistant"
3. "Heating & cooling"
