Notes:
▪ The operation area is extended to lower flow rates only in case the
unit operates with heat pump only, and the temperature of the flow
medium is sufficiently high. (This does not apply to start‑up
operation, defrost operation, and backup heater operation in case
a backup heater is installed.)
▪ About the dashed lines: the higher operation range limit is only
valid if the flow medium is water. If glycol is added to the system,
the limit is lower.
▪ Selecting a flow outside the operating area can damage the unit or
cause the unit to malfunction.
