Input for external sensor
An external differential pressure sensor can be used to
control the flow in the system to obtain the externally
set pressure, which results in following benefits:
• Minimises operating costs.
• Prevents valve noise.
• Ensures comfort (enough pressure).
Grundfos Eye

pump status indicator light providing information about
the pump operating status.
The indicator light will flash in different sequences and
provide information about the following:
• power on/off
