  • Seite 14: Summary Of Operations

    Two different models have been designed for different purposes: one model for space heating only and the other one for space heating as well as for DHW operation. For DHW operation (optional), HITACHI offers two specific YUTAKI S80 DHW tanks (DHWS200S-2.7H2E and DHWS260S-2.7H2E) which may be placed on top of the indoor unit or besides it, as an integrated unit to...
  • Seite 15 GENERAL INFORMATION Space cooling YUTAKI units can also be operated in cooling operation The dedicated “Cooling kit” accessory has been designed for this purpose. Combining the heating only models with these cooling kits, the reversible models become available. In this case, combination with fan-coils, refreshing floor or both (2nd temperature area) can be applied.
