Fig. 91: Heating/cooling quantity measurement
The heating or cooling quantity is recorded by the pump's volume flow detection and
checking the temperature in the feed and return.
For detecting the temperature, two temperature sensors must be connected to the
pump via the analogue inputs. They must be installed in the flow and return.
The heating and cooling quantity is identified separately based on the application.
NOTICE
With Stratos GIGA2.0, the differential pressure sensor is configured to AI1 at the
factory for determining the volume flow.
With Stratos GIGA2.0 ... R1, a differential pressure sensor must be mounted and con-
figured.
