[1] Automatic storage timing for domestic water heating

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 storage temperature is reached, no times are involved.

Automatic storage is the advised domestic hot water mode. In this mode water heats up during the night

(when space heating requirements are lower) until the storage set point. 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.

The storage temperature set point and timing are field settings.

 [1-00] Status: defines whether the domestic water heating (storage mode) during night is enabled (1)

or not (0).

 [1-01] Start time: time of the night at which the domestic water should be heated. The ending time

will variate for each system.

 [1-02] Status: defines whether the domestic water heating (storage mode) during daytime is enabled

(1) or not (0).

 [1-03] Start time: time of the day at which the domestic water should be heated. The ending time will

variate for each system.

Notes : 1. Make sure the domestic hot water is only heated up to the domestic hot water temperature you

require.

Start with a low domestic hot water storage temperature set point, and only increase if you feel that

the domestic hot water supply temperature is not sufficient for your needs (this depends on your water

using pattern).

2. Make sure the domestic hot water is not heated unnecessary. Start with activating automatic storage

during night (default setting). If it seems that the domestic hot water night storage operation is not

sufficient for your needs, an additional storage during daytime can be set.

3. For energy-saving purposes, it is advised to enable the weather dependent domestic water heating.

Refer to setting

“[b-02] Status: defines whether the weather dependent domestic water heating is

turned ON (1) or OFF (0).” on page 110.

4. Manual storage is possible: to activate push 5 seconds on the w button. The w icon starts to blink,

the water will be heated up till storage set point (one time action). It can also be stopped manually by

pushing the w button.

5. Be aware that despite the automatic storage is a pre-programmed schedule timer, it is only active

when the schedule timer is enabled. This means that you have to push the rp button and confirm that

the p is displayed to make sure that the automatic storage will operate.

Refer to "[b] Domestic hot water set points" for temperature set points.
