E Minimum water flow during defrost operation.
Notes:
▪ About the dashed lines: 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.)
▪ The upper operation range is only valid if the flow medium is
water. If glycol is added to the system, the operation range limit is
lower.
▪ Selecting a flow outside the operating area can damage the unit or
cause the unit to malfunction.
