Water flow rate through the unit in the space heating/cooling circuit
C
Minimum water flow rate during normal operation
D
Minimum water flow rate during Cooling operation
E
Minimum water flow rate during Heating/Defrost and Backup-Heater operation
Dashed lines:
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.
