• The data corresponding to "With simultaneous operation of electric heater in DHW tank" is calculated in combination with the YUTAKI S80 DHWT
accessory "DHWS(200/260)S-2.7H2E".
• The data corresponding to "Without simultaneous operation of electric heater in DHW tank" does not consider the consumption of simultaneous
operation of the electric heater in the domestic hot water tank (DSW4-3 set in OFF).
• The DHW tank heater is intended to be used in case that indoor and/or outdoor unit are out of order. If the heater operation of the DHW tank is
enabled during the indoor unit operation, the indoor unit CB and ELB may trip-OF. If it is desired to enable the DHW tank heater operation during
normal indoor unit operation, adjust de DSW4 pin 3 of the PCB1 in "ON" position and consider the recommended protections detailed in the data "
With simultaneous operation of electric heater in DHW tank).
