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.

A temperature sensor in the pump housing records either the feed or the return temperature, depending on its installation position.
A second temperature sensor must be connected to the pump using analogue inputs AI1 or AI2.

The heating and cooling quantity is identified separately based on the application.

Activating heating/cooling quantity measurement

In the “Diagnostics and measured values” menu, select

  1. “Heat/cooling quantity measuring”
  2. “Heat/cooling quantity On/Off”.

Then configure the sensor source and sensor position in the “Sensor feed temperature” and “Sensor return temperature” menu items.

Configuring the sensor source in the feed

In the “Diagnostics and measured values” menu, select

  1. “Heat/cooling quantity measuring”
  2. “Feed temperature sensor”
  3. “Select sensor source”.

Configuring the sensor source in the return

In the “Diagnostics and measured values” menu, select

  1. “Heat/cooling quantity measuring”
  2. “Sensor return temperature”
  3. “Select sensor source”.

Potential sensor source options:

  • Internal sensor
  • Analogue input (AI1)
  • Analogue input (AI2)
  • CIF module

Configuring the sensor position in the feed

  1. Select “Heat/cooling quantity measuring”
  2. “Feed temperature sensor”
  3. “Select sensor position”.

Select “Internal sensor”, “Feed” or “Return” as the sensor positions.

Configuring the sensor position in the return

  1. Select “Heat/cooling quantity measuring”
  2. “Sensor return temperature”
  3. “Select sensor position”.

Select “Internal sensor”, “Feed” or “Return” as the sensor positions.
