EKHBRD011~016ADV1+Y1Indoor unit for air to water heat pump system and options4P402192-1A – 2015.04Operation manual12Domestic water heatingDomestic water heating can be done through several standardoperation modes:• Automatic storage: by field setting, once during night and/oronce during the afternoon the water is heated till storage setpoint.• Manual storage: if due to special circumstances, productionof hot water (till storage set point) is needed immediately(1 time), this function can be used.• Reheat: the reheat function can be activated next to orseparate from the automatic storage operation if the userwants to keep the domestic hot water tank at the minimumreheat temperature.Next to the standard domestic water heating operation modes, it isalso possible to freely program the domestic water heating operationthrough the schedule timer (refer to "Programming quiet mode ordomestic water heating" on page 14). Then the mode is switched onor off at a scheduled time. Five actions can be programmed permode. These actions are repeated daily (additional schedule ofstorage on top of the automatic day and night storage functionality).Quiet modeRefer to "Programming quiet mode or domestic water heating" onpage 14.Switch the mode on or off at a scheduled time. Five actions can beprogrammed per mode. These actions are repeated daily.Programming and consulting the schedule timerProgramming the schedule timer is flexible (you can add, remove oralter programmed actions whenever required) and straightforward(programming steps are limited to a minimum). However, beforeprogramming the schedule timer, remind: Familiarize yourself with the icons and the buttons. You will needthem when programming. Refer to "Remote controller buttonsand icons" on page 3. Fill out the form at the very end of this manual. This form canhelp you define the required actions for each day. Keep in mindthat:- In the space heating program, depending on remotecontroller model 4 or 5 actions can be programmed perweekday. The same actions are repeated on a weekly basis.- In the domestic water heating and quiet mode program,depending on remote controller model 4 or 5 actions can beprogrammed per mode. The same actions are repeated on adaily basis. Take your time to enter all data accurately. Try to program the actions in a chronological way: start withaction 1 for the first action and end with the highest number forthe last action. This is not a requirement but will simplify theinterpretation of the program later. If 2 or more actions are programmed for the same day and at thesame time, only the action with the highest action number will beexecuted.Example: You can always alter, add or remove the programmed actionslater.NOTE Remark that only the time when domestic waterheating must start and stop can be programmedin the schedule timer. When domestic waterheating is enabled, the water will be heated tillstorage set point. The storage set point is setthrough field setting. For energy-saving reasons, keep hours with lowelectricity cost tariffs in mind when programmingthe schedule timer for domestic water heating.NOTE If the auto restart function is disabled, theschedule timer will not be activated when powerreturns to the unit after a power supply failure.Press the button to enable the schedule timeragain. When power returns after a power supply failure,the auto restart function reapplies the userinterface settings at the time of the power supplyfailure (if time is shorter than 2 hours). It istherefore recommended to leave the auto restartfunction enabled. The programmed schedule is time driven.Therefore, it is essential to set the clock and theday of the week correctly.Refer to "Setting the clock" on page 4. When the schedule timer is not enabled ( iconnot displayed), schedule timer actions will not beexecuted! The programmed actions are not stored accordingto their timing but according to the time ofprogramming. This means that the action that wasprogrammed first gets action number 1, eventhough it is executed after other programmedaction numbers.NOTE Remote controller model: 4 actionsRemote controller model: 5 actionsProgrammed actions Executed actionsTime(hour)Temperature(°C)Time(hour)Temperature(°C)1 16:00 — 22 1 06:00 — 212 18:00 — OFF 2 08:00 — 233 08:00 — 23 3 16:00 — 224 06:00 — 21 4 18:00 — OFF5 18:00 — 26
