In this mode, the indoor unit will deliver hot water to the domestic hot
water tank based on the daily fixed pattern. This mode will continue
until the storage temperature set point is reached. During operation
of this mode, the
icon will be blinking with 1 second intervals.
Automatic storage is the recommended domestic hot water mode. In
this mode, water heats up during the night (when space heating
requirements are lower) until the storage temperature set point is
reached. The heated water is stored in the domestic hot water tank at
a higher temperature so it can fulfil the domestic hot water
requirements throughout the day.
