2) Press the TIMER button to set the number of vacation days. Press ▲ or ▼ to

When the VACATION function is started under the On state, the water heater
calculates the number of vacation days accumulatively. And the STERILIZE function
will be started to sterilize the water tank one day before the vacation is over. In addition,
hot water is prepared by advance in the HOTWATER before the vacation is over.
Note:
① When time goes from 23:59 to 00:00, the system enters a new day, which is the
basis for increasing the number of days.
② Every time after the VACATION function is started or the number of vacation
days is adjusted in the vacation function setting interface, the number of
vacation days will be recalculated accumulatively. Even when the VACATION
function is being performed, operations such as vacation function resetting and
vacation day adjusting will also cause recalculation of the number of vacation
days.
③ After the VACATION function is set, the water heater can still precisely calculate
the number of vacation days accumulatively in the case of short-term power
failure. But ensure that there is no long-term power failure; otherwise, the clock
of the water heater will malfunction and the VACATION function will not work
properly.
