  • the heating element performance can be limited to a range of 50% to 80% of the nominal load.
  • Sleep Mode Function At 70°C or lower to reduce the energy consumption over night. Sleep mode is activated if there is no dispense for a certain time (the time can be selected for example 2hrs). To wake up the boiler module 60 the hot water dispense button needs to be selected and the heating element 71 will start to heat the pressure tank 80 until the defined temperature has been reached.
  • Heater Jump Start Function Every time a hot dispense button is selected the heating element 71 is switched on to avoid a delay. After the dispense buttons is released the heating element 71 continues to work in the normal temperature control mode.
  • the heating element 71 communicates with the dispensing head 14 and indicate readiness, or failures (e.g. "not ready” means the hot water is not hot enough to dispense (i.e. hot water ⁇ 90°C)), out of function, filter full), and option for GPRS communication for submitting the technical performance data.
  • Filter Lifetime Control can be selected by operating time or by throughput calculated by the valve opening time.
  • the usual setting is 6 months or 5000 liters throughput whatever appears first.
  • the standard flowrate is 21/min at the nozzle 18 which leads to a filter life time of 2500min or 41.66hrs valve opening time.
  • Safety Function maximum dispense is only allowed for the max portion size of 11.
  • Scale Detection System is used to detect if calcium deposits have settled on the heating element.
  • the boiler controller When heating up from sleep mode, the boiler controller will measure the temperature rise per time interval (dT/dt).
  • the default descaling interval will be 1 year. This default interval will be adjusted based on the described dT/dt measurement in the range of 0.5 to 1.2 years. If the sleep mode is never entered, the default descaling interval of 1 year will be used.
  • the scale detection system is used to give an early warning to the operator to indicate a possible problem with the heating element 71. To protect the heating element 71 a descaling service needs to be done to secure the heating element useful life.
  • the boiler module 60 can be set into an automatic sanitation mode where the filter unit 40 is replaced by a sanitation cartridge.
  • the control system activates the sanitation mode, controls the reaction time of the chemicals, and controls the flush time after sanitation. During this process the dispensing head 14 is deactivated.
  • the controller 114 is programmable and includes a processor 115 and a memory 116.
