Eco Mode Function - Hitachi TAW-270NH2A Operation Manual

ECO MODE FUNCTION

O
The ECO mode uses the heater pump for heating without engaging the electric heater. In ECO mode, you can use a
lower temperature for hot water temperature setting than is otherwise possible. It is a convenient feature for reducing
power consumption when less water is available.
Note: 1. Water temperature, outside temperature and other factors may increase the heating time and make it
impossible to reach the hot water temperature setting.
2. Anti-bacteria mode uses the electric heater. If you do not want to use the electric heater, turn anti-bacteria
mode off.
3. Electric heater operates in the case of compressor protection.
O
You can set a water temperature between 40 to 55°C. It is recommended that you set a water temperature that is
about 5°C lower than usual. The factory default setting is 50°C. A lower temperature setting will increase operating
efÀ ciency.
