The mode can be

The mode can be activated via the installer menu with the P1 parameter. • BOOST (button " " ) both heat pump and heating element are used to reach the set temperature in the shortest possible time. Once set temperature is reached, previous working mode is reactivated. • HOLIDAY To be used during a period of absence. After the period chosen Holiday mode is deactivated and the product will automatically start to work according to previous setting. Holiday mode is set by User Menu. In this mode no heating is performed, antifreeze protection and antibacterial cycle are guaranteed. USER MENU To access the user menu, press “ MENU ”. The word INFO will appear on the display. Press the “ + ” and “ - ” buttons to scroll the parameters U1, U2, U3 ... U10, the description of the parameter is shown in the line below. Once you have chosen the parameter press the “ SET ” button to select it. To go back to the parameter selection, press the “ MODE ” button. Therefore, each day of the week can be customised one by one by selecting the corresponding parameter. Warning: if the selected time period is too short, the desired temperature may not be reached. • PROGRAM SETTINGS U3 PRG SET parameter. Program Setting allows to customize the different working modes when U1 is ON. PARAMETER NAME U3.1 T MIN U3.2 PREHEAT PARAMETER DESCRIPTION Beyond the time slot, a minimum water temperature is guaranteed. Heat pump to pre-heat water: the set temperature is reached at the beginning of the selected time slots. Heat Pump pre-heat the water: set temperature is already achieved at the beginning of the selected time slots PARAMETER NAME PARAMETER DESCRIPTION U1 PROGRAM It selects different operating modes PROGRAM ON - TIME BASED: GREEN, COMFORT, FAST PROGRAM OFF - ALWAYS ACTIVE: GREEN, COMFORT, FAST, AUTO, HC-HP U2 PRGTIME User can select the desired time slots. U3 PRG SET User can customize the time programming U4 HOLIDAY To activate/deactivate the HOLIDAY mode When On is confirmed the user has to enter the number of days of absence as “Holiday Days" [1, 99] U5 ANTBACT Activated/deactivated status of the antibacterial function (on/off). U6 DATE To set the date (Year, Month, Day) and time (hours and minutes). User can enable/disable the auto switch among solar/daylight saving hours. U7 REPORTS It displays energy consumption (total). U8 SILENT To enable/disable the SILENT mode (On/Off) Recommended for unducted installation. U9 I-MRESET To reset the delivery profiles select On and press the SET button. The data saved in the memory is deleted and the learning starts from the current week. U10 WIFI RS WHERE AVAILABLE To reset the Wi-Fi data, select On and press the SET button. • TIME SCHEDULING U2 PRGTIME parameter. the user can set 4 different time slots for each day of the week in the operating modes GREEN, COMFORT and FAST. [START] and [STOP] define the beginning and the end of a time slot. After the fourth time slot, to reset the time slot selected and the ones after, press " - " until "OFF" is displayed and then press "SET". If a time slot is not set it remains as not defined. Example: the water heating system is active from 8 am to 12 pm and from 4 pm to 8 pm. [START1] = 8:00; [STOP1] = 12:00; [START2] = 16:00; [STOP2] = 20:00; [START3] = 00:00; [STOP3] = 00:00; [START4] = 00:00; [STOP4] = 00:00; If ALL_DAYS is selected the same time slots are assigned from Monday to Sunday. Then each day of the week can be customised one by one, selecting the corresponding parameter. INSTALLER MENU CAUTION! THE FOLLOWING PARAMETERS MUST BE ADJUSTED BY QUALI- FIED PERSONNEL The main product settings can be modified via the installer menu. The changeable parameters are shown on the display together with the spanner symbol “ ”. To enter the installer menu press the “MENU” button for 3 seconds, press the “ + ” and “ - ” buttons and enter the access code 234. PARAMETER P0 P1 P2 P3 P4 P5 P6 P7 P8 NAME PARAMETER DESCRIPTION Entering the code to access the installer menu. The display will show the number 222, press the “ + ” and CODE “ - ” and enter the code 234, press the “SET” button to confirm. It will then be possible to access the installer menu. Operation with two-tier power supply: 0. HC-HP_OFF (disabled default) HC-HP 1. HC-HP 2. HC-HP_40 3. HC-HP24h To disable/enable the antibacterial function ANTIBACT ON (function enabled) OFF (function disabled) Gives the temperature to be achieved [60/75 ° C] with T ANTB the antibacterial cycle and to be maintained for 1 hour at least. Adjustment of the maximum obtainable temperature T MAX [65 / 75 °C]. A higher temperature value allows for using a greater amount of hot water. Adjustment of the minimum obtainable temperature [40 /50 °C]. A lower temperature setting allows for T MIN more energy-efficient operation in the event of limited hot water consumption. Minimum temperature to be guaranteed in I-Memory I-M TMIN mode when no withdrawns have been detected by the algorithm Maximum water temperature that can be achieved with TMAX HP the heat pump only. It can be set by the installer in the [40 / 62 °C] range. Minimum air temperature that ensures the heat pump working; if air temperature goes below this value the TMINAIR compressor is inhibited. It can be set by the installer in the [-10, 10°C] range 20 /EN

P9 HYST HP Hysteresis value that allows the heat pump to restart after having achieved the target temperature. It can be set by the installer in the [3 / 12°C] range. P10 TANKVOL This parameter gives the capacity of the tank; it is useful in case of spare part customization. P11 PV MODE Operation with PV: 0. OFF (PV disabled - default) 1. PV_HP (PV with HP only) 2. PV_HE (PV with HP and HE1) 3. PV_HEHP (PV with HP and HE1 + HE2) P12 PV TSET This parameter gives the temperature to be achieved in PV mode. It can be set by the installer in the [55 / 75 °C] range. P13 SG MODE Operation with SG: 0. OFF (SG disabled - default) 1. HP_ON (SG enabled with HP only) P14 SYSMODE System Operation: 0.

After having done the electrical connections as described in paragraph 4.11 fig. 14 and set the P11 parameter to other than "0". The signal should be received at least for 5 minutes to enable the photovoltaic function (once the product starts a cycle, it will operate for at least 30 minutes). When the signal is detected, the operating mode works as follow:: - OFF (value 0 – default) PV mode disabled - PV_HP (value 1) When the signal from the inverter is present. The product will reach the set temperature (the highest between T SET POINT and PV TSET) with only the heat pump (max 62°C). - PV HE (value 2) The product will reach the set temperature (the highest between T SET POINT and PV TSET) operating with only the heat pump up to 62°C and if needed with the heating element (1500 W). - PV_HEHP (value 3) set temperature (the highest between T SET POINT and T W PV) is achieved with the heat pump and the heating element (1000 W) up to 62°C. For higher Temeratures than 62 °C the second heating element (1500 W) is activated. • P13 PARAMETER - SG FUNCTION If you have an SG signal, you can connect the signal cable as described in the "electrical connections" chapter when the function P13 is enabled the SG icon will be displayed. Once the SIG2 signal has been received for at least 5 minutes (once the product starts a cycle, it will work for at least 30 minutes), the name of the selected mode alternates with the text SG ON and the current operating mode is automatically changed by thermostating the product at set temperature (the maximum between T SET POINT and PV TSET), operating only with the heat pump (max 62 ° C). • P16 PARAMETER - SILENT This function reduces the sound level (performance can vary from those declared). It can be enabled via the P16 parameter on the installer's menu. Once activated, the symbol appears on the display " ". ANTI-FROST FUNCTION If the temperature of the water in the tank falls below 5 °C while the appliance is powered, the heating element (1000 W) will be automatically activated to heat the water up to 16 °C. DEFROST " " The defrost function is activated when the heat pump has been working for at least 20 minutes, the detected air temperature is below 15°C and the evaporator temperature is decreasing rapidly. When the defrost cycle is running, the icon to the side is displayed. 21 / EN
