OPERATION GENERAL INFORMATION General information Safety The chapter Operation is intended for users and heating Intended use contractors. The appliance is designed to: The chapter Installation is intended for heating contractors. — Heat buildings. Subject to the relevant system, also observe the operating and installation instructions of the components that are part of the Observe the operating limits listed in the speciﬁcation table.
Page 4: Appliance Description
OPERATION APPLIANCE DESCRIPTION Appliance description Operation Properties Heat pump manager WPM The appliance is an air source heat pump that operates as a heating heat pump. Heat is extracted from the outside air at a low temperature level, which is then transferred to the heating water at a higher level. The heating water can be heated up to a ﬂow temperature of 75 °C.
