In case of frequent reheat operation, space heating/cooling function is regularly interrupted. 5.7.2 Scheduled mode In scheduled mode the DHW tank produces hot water corresponding to a schedule. The best time to allow the tank to produce hot water is at night, because the space heating demand is lower. Example: Tt 60°C 50°C 40°C 1 2 3 4 5 15°C 00:00 07:00 14:00 21:00 t Tt DHW tank temperature t Time Initially, the DHW tank temperature is the same as the temperature of the domestic water entering the DHW tank (example: 15°C). At 00:00 the DHW tank is programmed to heat up the water to a preset value (example: Comfort = 60°C). During the morning, you consume hot water and the DHW tank temperature decreases. At 14:00 the DHW tank is programmed to heat up the water to a preset value (example: Eco = 50°C). Hot water is available again. During the afternoon and evening, you consume hot water again and the DHW tank temperature decreases again. At 00:00 the next day, the cycle repeats. 5.7.3 Scheduled + reheat mode In scheduled + reheat mode, the domestic hot water control is the same as in scheduled mode. However, when the DHW tank temperature drops below a preset value (=reheat tank temperature hysteresis value; example: 35°C), the DHW tank heats up until it reaches the reheat set point (example: 45°C). This ensures that a minimum amount of hot water is available at all times. Example: Tt 60°C 50°C 45°C 1 2 3 4 5 35°C 15°C 00:00 07:00 14:00 21:00 t Tt Domestic hot water tank temperature t Time 5.7.4 Using DHW powerful operation About powerful operation Powerful operation allows the domestic hot water to be heated by the backup heater or booster heater. Use this mode on days when there is more hot water usage than usual. Operation manual 13 5 Operation To check if powerful operation is active If is displayed on the home screen, powerful operation is active. Activate or deactivate Powerful operation as follows: 1 Go to [5.1]: Tank > Powerful operation 2 Turn powerful operation Off or On. Usage example: You immediately need more hot water You are in the following situation: You already consumed most of your domestic hot water. You cannot wait for the next scheduled action to heat up the domestic hot water tank. Then you can activate powerful operation. The domestic hot water tank will start heating up the water to the Comfort temperature. INFORMATION When powerful operation is active, the risk of space heating/cooling and capacity shortage comfort problems is significant. In case of frequent domestic hot water operation, frequent and long space heating/cooling interruptions will happen. 5.8 Schedule screen: Example This example shows how to set a room temperature schedule in heating mode for the main zone.

Weather-dependent operation The unit operates 'weather dependent' if the desired leaving water or tank temperature is determined automatically by the outdoor temperature. It therefore is connected to a temperature sensor on the North wall of the building. If the outdoor temperature drops or rises, the unit compensates instantly. Thus, the unit does not have to wait for feedback by the thermostat to increase or decrease the temperature of the leaving water or tank. Because it reacts more quickly, it prevents high rises and drops of the indoor temperature and water temperature at tap points. Advantage Weather-dependent operation reduces energy consumption. Weather-dependent curve To be able to compensate for differences in temperature, the unit relies on its weather-dependent curve. This curve defines how much the temperature of the tank or leaving water must be at different outdoor temperatures. Because the slope of the curve depends on local circumstances such as climate and the insulation of the house, the curve can be adjusted by an installer or user. Operation manual 15 5 Operation Types of weather-dependent curve There are 2 types of weather-dependent curves: 2-points curve Slope-offset curve Which type of curve you use to make adjustments, depends on your personal preference. See "5.9.4 Using weather-dependent curves" 4[ 17]. Availability The weather-dependent curve is available for: Main zone - Heating Main zone - Cooling Additional zone - Heating Additional zone - Cooling Tank (only available to installers) INFORMATION To operate weather dependent, correctly configure the setpoint of the main zone, additional zone or tank. See "5.9.4 Using weather-dependent curves" 4[ 17]. 5.9.2 2-points curve Define the weather-dependent curve with these two setpoints: Setpoint (X1, Y2) Setpoint (X2, Y1) Example a Y2 Y1 X1 X2 Item Description a Selected weather dependent zone: : Main zone or additional zone heating : Main zone or additional zone cooling X1, X2 Y1, Y2 : Domestic hot water Examples of outdoor ambient temperature Examples of desired tank temperature or leaving water temperature. The icon corresponds to the heat emitter for that zone: : Underfloor heating : Fan coil unit : Radiator : Domestic hot water tank Possible actions on this screen Go through the temperatures. Change the temperature. Go to the next temperature. Confirm changes and proceed. 5.9.3 Slope-offset curve Slope and offset Define the weather-dependent curve by its slope and offset: Change the slope to differently increase or decrease the temperature of the leaving water for different ambient temperatures. For example, if leaving water temperature is in general fine but at low ambient temperatures too cold, raise the slope so that leaving water temperature is heated increasingly more at decreasingly lower ambient temperatures. Change the offset to equally increase or decrease the temperature of the leaving water for different ambient temperatures. For example, if leaving water temperature is always a bit too cold at different ambient temperatures, shift the offset up to equally increase the leaving water temperature for all ambient temperatures. Examples Weather-dependent curve when slope is selected: c a b e d Y4 Y3 Y2 Y1 X1 X2 Weather-dependent curve when offset is selected: c a b e d Y4 Y3 Y2 Y1 X1 X2 Item a b c d e Description WD curve before changes. WD curve after changes (as example): When slope is changed, the new preferred temperature at X1 is unequally higher than the preferred temperature at X2. When offset is changed, the new preferred temperature at X1 is equally higher as the preferred temperature at X2. Slope Offset Selected weather dependent zone: : Main zone or additional zone heating : Main zone or additional zone cooling : Domestic hot water X1, X2 Examples of outdoor ambient temperature Operation manual 16 ETVH/X16S(U)18+23EA6V+9W + ETBH/X16EF6V+9W Daikin Altherma 3 H HT F+W 4P644732-1 2021.02 Item Y1, Y2, Y3, Y4 Description Examples of desired tank temperature or leaving water temperature. The icon corresponds to the heat emitter for that zone: : Underfloor heating : Fan coil unit : Radiator : Domestic hot water tank Possible actions on this screen Select slope or offset. Increase or decrease the slope/offset. When slope is selected: set slope and go to offset. When offset is selected: set offset. Confirm changes and return to the submenu. 5.9.4 Using weather-dependent curves Configure weather-dependent curves as following: To define the setpoint mode To use the weather-dependent curve, you need to define the correct setpoint mode: Go to setpoint mode ...

Restriction: Only available to installers. [5.C] Tank > WD curve INFORMATION Maximum and minimum setpoints You cannot configure the curve with temperatures that are higher or lower than the set maximum and minimum setpoints for that zone or for the tank. When the maximum or minimum setpoint is reached, the curve flattens out. To fine-tune the weather-dependent curve: slope-offset curve The following table describes how to fine-tune the weatherdependent curve of a zone or tank: You feel ... Fine-tune with slope and offset: At regular outdoor At cold outdoor temperatures ... temperatures ... Slope Offset OK Cold -- OK Hot -- Cold OK Cold Cold -- Cold Hot Hot OK Hot Cold Hot Hot -- To fine-tune the weather-dependent curve: 2-points curve The following table describes how to fine-tune the weatherdependent curve of a zone or tank: You feel ...

Each saved degree can save up to 6% of heating/cooling costs. Do NOT increase/decrease the desired room temperature to speed up space heating/cooling. The space will NOT heat up/cool down faster. When your system layout contains slow heat emitters (example: underfloor heating), avoid large fluctuation of the desired room temperature and do NOT let the room temperature drop too low/ rise too high. It will take more time and energy to heat up/cool down the room again. Operation manual 17 7 Maintenance and service Use a weekly schedule for your normal space heating or cooling needs. If necessary, you can easily deviate from the schedule: For shorter periods: You can overrule the scheduled room temperature until the next scheduled action. Example: When you have a party, or when you are leaving for a couple of hours. For longer periods: You can use the holiday mode. Tips about DHW tank temperature Use a weekly schedule for your normal domestic hot water needs (only in scheduled mode). Program to heat up the DHW tank to a preset value (Comfort = higher DHW tank temperature) during the night, because then space heating demand is lower. If heating up the DHW tank once at night is not sufficient, program to additionally heat up the DHW tank to a preset value (Eco = lower DHW tank temperature) during the day. Make sure the desired DHW tank temperature is NOT too high. Example: After installation, lower the DHW tank temperature daily by 1°C and check if you still have enough hot water. Program to turn ON the domestic hot water pump only during periods of the day when instant hot water is necessary. Example: In the morning and evening. 7 Maintenance and service 7.1 Overview: Maintenance and service The installer has to perform a yearly maintenance. You can find the contact/helpdesk number via the user interface. 1 Go to [8.3]: Information > Dealer information. As end user, you have to: Keep the area around the unit clean.

The weather-dependent curve is Adjust the weather-dependent set incorrectly. curve. See "5.9 Weather- dependent curve" 4[ 15]. 8.4 Symptom: The water at the tap is too cold Possible cause You ran out of domestic hot water because of unusual high consumption. The desired DHW tank temperature is too low. Corrective action If you immediately need domestic hot water, activate the DHW tank Powerful operation. However, this consumes extra energy. See "5.7.4 Using DHW powerful operation" 4[ 13]. If the problems recurs daily, do one of the following: Increase the DHW tank temperature preset value. See the user reference guide. Adjust the DHW tank temperature schedule. Example: Program to additionally heat up the DHW tank to a preset value (Eco setpoint = lower tank temperature) during the day. See "5.8 Schedule screen: Example" 4[ 14]. 8.5 Symptom: Heat pump failure When the heat pump fails to operate, the backup heater and/or booster heater can serve as an emergency heater. It then takes over the heat load either automatically or by manual interaction. When Emergency is set to Automatic and a heat pump failure occurs: For ETVH/X: The backup heater automatically takes over the domestic hot water production and space heating. For ETBH/X: The backup heater automatically takes over the heat load, and the booster heater in the optional tank takes over the domestic hot water production. 8 Troubleshooting When Emergency is set to Manual and a heat pump failure occurs, the domestic hot water heating and space heating stops. To manually recover it via the user interface, go to the Malfunctioning main menu screen and confirm whether the backup heater and/or booster heater can take over the heat load or not. Alternatively, when Emergency is set to: auto SH reduced/DHW on, space heating is reduced but domestic hot water is still available. auto SH reduced/DHW off, space heating is reduced and domestic hot water is NOT available. auto SH normal/DHW off, space heating operates as normally but domestic hot water is NOT available. Similarly as in Manual mode, the unit can take the full load with the backup heater and/or booster heater if the user activates this via the Malfunctioning main menu screen. When the heat pump fails, interface. Possible cause Heat pump is damaged. or will appear on the user Corrective action See "8.1 To display the help text in case of a malfunction" 4[ 18]. INFORMATION When the backup heater or booster heater takes over the heat load, electricity consumption will be considerably higher. 8.6 Symptom: The system is making gurgling noises after commissioning Possible cause There is air in the system. Corrective action Purge air from the system.(a) Incorrect hydraulic balance. 1 Perform hydraulic balancing to assure that the flow is correctly distributed between the emitters. 2 If hydraulic balancing is not sufficient, change the pump limitation settings ([9-0D] and [9-0E] if applicable). Various malfunctions. Check if or is displayed on the home screen of the user interface. See "8.1 To display the help text in case of a malfunction" 4[ 18] for more information about the malfunction. (a) We recommend to purge air with the air purge function of the unit (to be performed by the installer). If you purge air from the heat emitters or collectors, mind the following: WARNING Air purging heat emitters or collectors. Before you purge air from heat emitters or collectors, check if or is displayed on the home screen of the user interface. If not, you can purge air immediately. If yes, make sure that the room where you want to purge air is sufficiently ventilated. Reason: Refrigerant might leak into the water circuit, and subsequently into the room when you purge air from the heat emitters or collectors.
