» Ground source
The application wizard in the Assist menu helps
you set the correct control mode.
Example: Ground source
Firstly, identify your pump in the application
overview to the left. Secondly, choose “Ground
source” in the application wizard and press “OK”.
Then select either “Ground loop” or ”Distribution
side” depending on the position of the pump.
Press “OK”. Keep choosing the characteristics
corresponding to your system until the setup is
complete.
Tip!
By using the pump’s internal sensor and installing
another temperature sensor on the return pipe,
you are able to measure the dierence between
the inlet and outlet temperatures; the Delta-T (ΔT).
Knowing Delta-T is especially useful in ground
source applications, as the pump performance can
be regulated to ensure a specic Delta-T value.
