? NOTE
• (*1): If Heating source (HES)= “HP+Heat.+Boil.”, Bivalent point (BOBP) has a range withing -15 and 20ºC.
• (*2): If Heating source (HES)= “HP+Heat.+Boil.”, the bivalent point for electric heater must be equal or higher than the bivalent point for boiler + 5
ºC of offset (Bivalent point (HEBP) ≥ Bivalent point (BOBP) + 5 ºC).
• (*3): If Status (DHWs)= “Enabled”. This parameter is not displayed in case of YUTAKI S80 (Version for combination with DHW).
