Installation / AdjustmentDescription of functions - Basic functionsHot waterThe need of hot water production is created when thetemperature on the hot water sensor (VVG) drops belowthe temperature set in menu 1.1. The need ceases whenthe temperature exceeds the set temperature in menu 1.2.When two or more compressors are programmed for hotwater charging, these are engaged and disengaged with0.5 degrees minus difference for starting and stopping.Thevalue can be set in menu 1.8. That’s to say, if compressor 1starts at 50 °C and stops at 55 °C then compressor 2 startsat 49.5 °C and stops at 54.5 °C i.e. each F1330 connectedfor possible switching between hot water and heating hasits own shuttle valve.Hot water mode normally has priority over heating mode.However, it is possible to set the period time and max timefor hot water production in menus 1.6 and 1.7.When in heating mode, the hot water temperature ismeasured before stopping. With less than 2 degrees to hotwater start, hot water mode will start using one compressordirectly without stopping, once the heating requirementis reached.Connection of hot water productionThe shuttle valve (VXV) is connected to the terminal blockX6:3 (230 V), X6:4 (N), X6:5 (230 V with heat production)and X6:6 (230 V with hot water production).The hot water sensor (VVG) is installed in the water heater’ssubmerged tube. The sensor must make good contactwith the measurement area to give the best function. Thesensor is connected to screw terminals X4:11 and X4:12 onthe EBV-card.X6+EBV-cardX4X4LEKThe heat pump in the picture is fitted with accessories.Quick guide - menu settingshot water productionMenu 1.1 Start temperature HW[U]The temperature when the heat pump starts to workwith the hot water production is set here. When bracketsare shown, this means the high pressure pressostathas tripped during hot water charging and F1330 hasautomatically lowered the set temperature by the valuein brackets. The reduction is removed when the value ischanged. The value is adjustable between 5 and 55 °C.The factory setting is 45 °C.Menu 1.2 Stop temperature HW[U]The temperature when the heat pump stops workingwith the hot water production is set here. When bracketsare shown, this means the high pressure pressostathas tripped during hot water charging and F1330 hasautomatically lowered the set temperature by the valuein brackets. The reduction is removed when the value ischanged. The value is adjustable between 20 and 60 °C.The factory setting is 50 °C.Menu 1.6 Periodtime HW/Heat.[U]The length of the period time for hot water productionand heating are set here. The value is adjustable between0 and 60 minutes. The factory setting is 60 minutes.Menu 1.7 Maxtime HW-product.[U]Here you select how much time of the period time (menu1.6) is to be used to heat the hot water when there is aneed of both heating and hot water. The value is adjustablebetween 0 and 60 minutes. The factory setting is 60minutes.24 NIBE F1330
