This setting is only effective if simultaneous operation ofthe Booster Heaters (BOH) and the heat pump is permitted([4-03] is not set to 0).– [6-03] Priority of "High Output" operating mode: stipulates thepriority if the operating modes "Low Noise" and "High Output"are active at the same time.– [6-04] Stages in the operating mode "Low Noise":– 1 = Lowest noise reduction.– 2 = Medium noise reduction.– 3 = Highest noise reduction.[7-00] - Low tariff mains connection (HT/LT) / SmartGrid connection (SG)These parameters facilitate the configuration of the DAIKIN Hotwater heat pump with an existing low tariff mains connection andSmart Grid connection.As soon as the function is activated by the parameter [7-00] > 0,the operation of the DAIKIN Hot water heat pump is changed, de-pending on the switch position of the connected potential-free ex-ternal switching contact.The following setting options are available:– [7-00]: Stipulation as to whether the heat pump is connectedto a low tariff mains connection / Smart Grid connection.– 0 = Normal mains connection (default setting).– 1 = Evaluation low tariff mains connection.– 2 = Evaluation low tariff mains connection.– 3 = Evaluation low tariff mains connection and Smart Gridconnection.[7-01] Switch hysteresis Booster Heater (BOH)If the hot water set temperature is set to a value which is abovethe maximum hot water temperature achieved in exclusively heatpump mode, the electrical Booster Heater (BOH) is switched infor hot water generation (see fig. 5-6).The following setting options are available:– [7-01] Switching hysteresis Booster Heater (BOH) when hotwater set temperature is above the maximum possible hotwater temperature in exclusively heat pump mode.Factory setting 2 KAn ON temperature > 45°C makes sure that onlythe electrical Booster Heater (BOH) is used and notthe heat pump. This increases the usage duration ofthe refrigerant compressor.In the operating modes "ECO" and "Automatic" thehot water heating mode only starts when themeasured hot water temperature falls below 45°C.T Water temperatureT HP MAX Maximum water temperature of the heat pump at thetemperature sensor in the hot water storage tank (55°C)T HP OFF OFF temperature of the heat pumpT HP ON ON temperature of heat pumpT U hot water temperature (as set on the controller)Fig. 5-5 Illustration of the control system for hot water generation bythe heat pumpSettingsOperatingmodeOperating mode[6-03] Off [6-04] = 1 [6-04] = 2 [6-04] = 30 OFF Normal Low Noise 1 Low Noise 2 Low Noise 3ON High output Normal Low Noise 1 Low Noise 21 OFF Normal Low Noise 1 Low Noise 2 Low Noise 3ON High output High output High output High outputTab. 5-2 Overview of operating modes "Low Noise" and "HighOutput" with simultaneous activationIf [6-03] is set to "1", the operating mode "High Out-put" has priority over the operating mode "LowNoise".[7-00] Assessment contact Behaviour of heatpumpHT / LT SMARTGRID0 (default) — — Normal operatingmode1Open — Normal mode(low tariff)Closed — Reduced mode(high tariff)2Open — Reduced mode(high tariff)Closed — Normal mode(low tariff)3Open Open Normal operatingmodeClosed Open Reduced mode,expensive powerOpen Closed Switch-on recom-mendation,cheap powerClosed Closed Switch-oncommand,cheap powerTab. 5-3 Configuration table parameter [7-00]
