Accuracy of the displayed and recorded operating data
Volume flow
The volume flow is determined with the help of the connected differential pressure sensor.
The accuracy of the volume flow specification with pure water is approx. +/- 5 % of the
duty point.
If a water-glycol mixture is used, the accuracy is in the range of +/-10 % ... 50 % depend-
ing on the mixing ratio.
Temperature
External sensors such as PT1000 must always be connected for temperature measurement.
Accuracy information is not available here as it depends on the following factors:
• how and where temperature sensors are installed on the piping;
• which accuracy class of the sensor was selected;
• length of the sensor cable.
The accuracy within the Stratos GIGA2.0 is up to +/- 2 K depending on the temperature
value.
Heating/cooling quantity measurement
Installation and operating instructions • Wilo-Stratos GIGA2.0-I, Wilo-Stratos GIGA2.0-D • Ed.02/2022-07
NOTICE
The energy measurement for heating or cooling can be conducted without
an additional energy meter. The measurement can be used for the internal
distribution of heating and cooling costs or for system monitoring. As the
heating and cooling quantity measurement is not calibrated, it cannot be
used as the basis for billing.
NOTICE
For constant recording of the heating/cooling quantity without interrupt-
ing data recording, the pump must only be switched on/off via a digital in-
put with EXT. OFF. There is no data recording when the mains voltage is
switched off.
