Beyond the basic signal functions, ecocirc PREMIUM configuration is
equipped with a digital display as well. The display provides
information on the actual hydraulic performance and electrical power of
the pump on the following way: The display shows the electrical power
of the pump in Watts for 10 seconds, than shows the elevated water
column height (differential pressure) in meters for 10 seconds, than the
actual flow in m3/h for 10 seconds. Than the display returns to the
energy consumption in Watts and the cycle starts again.
The PREMIUM display messages also provide detailed information on
the air purge mode status as well as detailed error messages:
