SELECTING THE OPERATING MODE
The RePuro heat recovery unit can be controlled by two operating modes:
• AUTOMATIC: Once this mode is selected the heat recovery unit is activated on for the time period set in the parameter “Clean-
ing time”, forcing the fans to maximum speed. At the end of the “Cleaning time” the heat recovery unit automatically reverts to
manual mode.
• MANUAL: This mode activates the heat recovery unit and keeps it active until the key to switch off the unit is pressed (key shown
in paragraph 5.1). During this mode the fans operate at the speed selected by parameters PO1 and PO2.
To select one of these modes it is necessary to press the key shown in the diagram below. Each press of the key passes the operat-
ing modes from one to the next (the same key enables or disables any heaters, and the function is shown by the appearance or
disappearance of the AUX icon), as shown in the following diagram:
If this icon is present then the ac-
tive operating mode is AUTOMAT-
IC, whilst if the icon is not seen the
unit is controlled in MANUAL mode
If the heat recovery unit is
