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).
ESP=External static pressure [kPa] in the space heating/cooling
circuit.
Flow=Water flow through the unit in the space heating/cooling
circuit.
Notes:
▪ Selecting a flow outside the area of operation can cause damage
or malfunction of the unit. See also the minimum and maximum
allowed water flow range in the technical specifications.
▪ Water quality MUST be according to EN directive EC98/83EC.
