[. . . ] [b-03] set point: storage temperature (see figure "Domestic water heating modes" on page 6). [b-02] Status: defines whether the weather dependent domestic water heating is turned ON (1) or OFF (0). If enabled, the storage set point will be set weather dependent. In case of a higher ambient temperature (e. g. during summertime), temperature of supply water to the domestic hot water tank will be higher too, so that storage temperature set point can be set lower in order to keep the overall equivalent hot water amount the same during the whole year. Therefor it is recommended to use this function. Remark that the w icon will only be blinking during effective operation. During the operation it is always possible to cancel the operation by pushing the w button once. Be aware that after pushing the w button, it is possible that the permanently lit w icon still displays, meaning that the reheat function is enabled. The storage temperature set point is a field setting. Refer to the chapter "Field settings" on page 14 for a detailed description how to set one or more field settings.

EKHBRD011~016AAV1+Y1 Operation manual 7 Indoor unit for air to water heat pump system and options 4PW54466-1A Manual storage is deactivated automatically when the set point for the domestic hot water storage temperature is reached. It can also be stopped at any time by pushing the w button. Other operation modes Start up operation (d) Reheat This mode will prevent the domestic hot water from cooling down lower than a certain temperature. When enabled the indoor unit will deliver hot water to the domestic hot water tank when the reheat minimum value is reached. The domestic water heating will continue until the reheat maximum temperature is reached. Selecting reheat operation for domestic water heating 1 Use the w button to enable reheat operation. The w icon will display. NOTE During start up, the d icon displays, indicating that the heat pump is starting up and is not working in a steady state condition. Defrost operation (d) In space heating operation or domestic water heating operation, freezing of the outdoor heat exchanger may occur due to low outdoor temperature. If this risk occurs, the system goes into defrost operation. It reverses the cycle and takes heat from the indoor system to prevent freezing of the outdoor system. [. . . ] When exiting FIELD SET MODE, "88" may be displayed on the remote controller LCD while the unit initializes itself.

This maintenance should be carried out by your local Daikin technician (see installation manual). The only maintenance which may be required by the operator is: keeping the remote controller clean by means of a soft damp cloth, checking if the water pressure indicated on the manometer is above 1 bar.
