The “OV-DMC 3” software enables valves to
be adjusted using a range of measurement
methods. During this process measurement
values (differential pressure and flow rate) are
given and displayed graphically. The supply
flow and return flow temperatures can addition
-
ally be determined if temperature sensors are
connected. The measured values are used to
determine, display, and log the presets for the
valves.
