Operation area is extended to lower flow rates only in case the unit
operates with heat pump only. (Not in startup, no backup heater operation, no
defrost operation.)
Notes:
▪
Selecting a flow outside the operating area can damage the unit or cause the unit
to malfunction. See also the minimum and maximum allowed water flow range in
the technical specifications.
▪
Make sure water quality complies with EU directive 2020/2184.
