INFORMATION When the DHW tank mode is reheat, the risk for capacity shortage and comfort problem is significant. In case of frequent reheat operation, space heating/cooling function is regularly interrupted. 4.5.3 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: t 60°C 00:00 07:00 50°C 15°C 40°C 14:00 21:00 1 2 3 4 5 Tt 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. 4.5.4 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: t Tt 60°C 00:00 07:00 50°C 45°C 15°C 14:00 21:00 35°C 1 2 4 5 3 Tt DHW tank temperature t Time 4.5.5 To change the domestic hot water temperature In Reheat only mode, you can use the room temperature setpoint screen to read out and adjust the domestic hot water temperature. 1 Go to [5]: Tank. You can read out the desired and actual room temperature in the center of the setpoint screen. 2 Turn the right dial to adjust the domestic hot water temperature. In other modes, you can only view the setpoint screen but not modify it. Instead, you can modify the settings for the Comfort setpoint [5.2], Eco setpoint [5.3] and Reheat setpoint [5.4]. 4.5.6 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. 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. 4.6 Advanced usage The amount of information you can read out in the menu structure depends on your user permission level: ▪User: Standard mode ▪Advanced user: You can read out more information To change the user permission level You can change the user permission level as follows:

Each saved degree can save up to 6% of heating/cooling costs. ▪Do NOT increase the desired room temperature to speed up space heating. The space will NOT heat up faster. ▪When your system layout contains slow heat emitters (example: under floor heating), avoid large fluctuation of the desired room temperature and do NOT let the room temperature drop too low. It will take more time and energy to heat up the room again. ▪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 leaving water temperature ▪In heating mode, a lower desired leaving water temperature results in lower energy consumption and better performance. In cooling, the opposite is valid. ▪Set the desired leaving water temperature in accordance with the heat emitter type. Example: Underfloor heating is designed for lower leaving water temperature than radiators and heat  pump convectors. 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. 6 Maintenance and service 6.1 Overview: Maintenance and service The installer has to perform a yearly maintenance. You can find the contact/helpdesk number via the user interface. As end user, you have to: ▪Keep the area around the unit clean. ▪Keep the user interface clean with a soft damp cloth.

Increase (decrease) the desired room temperature. If the problem recurs daily, do one of the following: ▪Increase (decrease) the room temperature preset value. ▪Adjust the room temperature schedule. The desired room temperature cannot be reached. Increase the desired leaving water temperature in accordance with the heat emitter type. 7.4 Symptom: The water at the tap is too cold Possible cause Corrective action You ran out of domestic hot water because of unusual high consumption. If you immediately need domestic hot water, activate the DHW tank Powerful operation. However, this consumes extra energy. If you can wait, overrule (increase) the active or next scheduled desired temperature so that more hot water will be produced exceptionally. If the problems recurs daily, do one of the following: ▪Increase the DHW tank temperature preset value. ▪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. The desired DHW tank temperature is too low. 7.5 Symptom: Heat pump failure When the heat pump fails to operate, the backup heater and/or booster heater can serve as an emergency heater and either automatically or non-automatically take over the heat load. ▪When auto emergency is set to Automatic and a heat pump failure occurs: ▪For EHVH/X: The backup heater will automatically take over the heat load and domestic hot water production ▪For EHBH/X: The backup heater will automatically take over the heat load, and the booster heater in the optional tank will automatically take over the domestic hot water production. ▪When auto emergency is set to Manual and a heat pump failure occurs, the domestic hot water and space heating operation will stop and need to be recovered manually via the user interface. To recover operation manually, go to the Malfunctioning main menu screen, where the user interface will then ask you to confirm whether the backup heater and/or booster heater can take over the heat load or not.
