NOTE FOR DHW MODE: leaving water temperature is the tem-
perature of the water produced by the unit and not the DHW tem-
perature available to the user; the DHW temperature is in fact a
function of this parameter and of the coil surface of the DHW boiler.
Operation range by heat pump with
possible limitation and protection.
