Operation range
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.
