Function description – Vitocontrol-S, WB2BCascade control unitBrief descriptionThe supply temperature is regulated bystarting or stopping the burner or bystarting/stopping individual burners.The boilers will be controlled to the setboiler water temperature determined bythe cascade control (stand-alone typeof control).Subject to the system design, you mayselect between one gross calorificstrategy and two net calorificstrategies.The boiler sequence (see page 62) canbe determined via coding 2 and theboiler sequence selection.Coding addresses which influence thecascade control35 to 3F, 41 to 4F.For a description, see the codingoverview.Set supply temperatureThe set supply temperature isdetermined fromthe set supply temperature set-pointvalues of system circuit A1 andmixing valve circuits M2 and M3,the set supply temperature values ofadditional heating circuits (e.g.Vitotronic 200-H),the set DHW temperature andexternal demands (e.g. the setsupply temperature defaulted bycoding address 9b or via the InputModule 0 to 10 V).Upper control limitElectronic maximum system supplytemperature limit.Setting range: 68 to 261˚F / 20 to127˚C.The maximum supply temperature limitcan be adjusted via coding address 37.This value must be set no higher thanthe lowest value of coding address 06of all connected Vitotronic 100, HC1.Lower control range limitElectronic minimum system supplytemperature limit.Setting range: 68 to 261˚F / 20 to127˚C.The minimum supply temperature limitcan be adjusted via coding address 36.5414 553 v1.458

Function description – Vitocontrol-S, WB2BCascade control (continued)Control sequenceStand-alone type of control: Parallel boiler control(coding 3b : 0 without supply temperature sensor orcoding 3b : 1 with supply temperature sensor)The cascade control unit defaults theset boiler water temperature to allcurrently active boilers.Every Vitotronic 100 individuallyregulates the dafaulted settemperature.The control sequence is subject to thestart-up and shutdown criteria selectedwith control strategy (coding address3C):Gross calorific strategy.Net calorific strategy 1.Net calorific strategy 2.Without supply temperature sensor:The control deviation is calculated fromthe set boiler water temperature andthe estimated average actual boilerwater temperture of the active boiler todetermine the start-up and shutdowncriteria. Only those boilers are takeninto consideration whose boiler circuitpumps are not switched OFF.With supply temperature sensor:The contro deviation is calculated fromthe set supply temperature and theactual supply temperature to determinethe start-up and shutdown criteria.Gross calorific strategy (Condensing strategy)It is the aim of the gross calorificstrategy to operate as many boilers aspossible at the lowest output(modulation) level.Start-up criterionBoilers are started via an outputstatement (coding 3d : 1).An additional boiler will be startedwhen the currently required output canalso be achieved by the currently activeboiler plus the next boiler in the boilersequence (see page 69).AdvantagesOptimum utilization of thecondensing effect (as many boilersactive as possible)Long burner operating timesShutdown criterionThe boiler is shut down via a shutdownintegral.

Function description – Vitocontrol-S, WB2BDHW tank temperature controlBrief descriptionThe DHW tank control logic is aset-point control. It is the result ofstarting and stopping the DHW pump.The switching differential is ±4.5˚F /2.5˚C.FunctionsTime programAn automatic program or an individualtime program may be selected for DHWheating and the control of the DHWrecirculation pump.Compared with the space heatingcircuit’s heat-up phase, DHW heatingin automatic mode starts 30 minutesearlier.The individual time program enables upto four switching periods per day to beset via the time switch to control theDHW heating/heating and the DHWrecirculation pump.Any DHW tank heating sequence willbe completed, independent of the timeprogram.During DHW tank heating, a constantboiler supply temperature will be set(36˚F / 20˚C higher than the set DHWtank temperature, adjustable via codingaddress 60) and space heating isswitched OFF (optional DHW tankpriority).In conjunction with coding address 7F7F: 1 Detached house:Automatic mode:For systems with two or three spaceheating circuits, the heating times forthe first of the existing heatingcircuits will be applied.Individual time program:The switching times for DHW heatingand the DHW recirculation pumphave the same effect on all heatingcircuits.Coding addresses which influence theDHW tank control54 to 75, 7F, A2.For a description, see the codingoverview.7F : 0 Apartment building:Automatic mode:For systems with two or threeheating circuits, the heating timesfor the respective heating circuitwill be applied.Individual time program:The switching times for DHW heatingcan be adjusted separately for eachheating circuit.DHW priorityWith DHW priority (coding A2: 2):The set supply temperature will beset to 32˚F / 0˚C while the DHWtank is being heated.The mixing valve closes, and theheating circuit pumps are switchedOFF.With DHW priority:The heating circuit control unitcontinues to operate with the sameset value.Frost protectionThe DHW tank will be heated to 68˚F /20˚C, if the DHW temperature fallsbelow 41˚F / 5˚C.Auxiliary functions – DHW heatingThis function is activated by providinga second set DHW temperature viacoding address 58 and activating the4 th DHW phase for DHW heating.Set DHW temperatureThe set DHW temperature can beadjusted between 50 and 140˚F / 10and 60˚C.

The 2 nd DHWtank temperature sensor (inside thecold water inlet) is designed toprematurely start DHW tank heatingwhen large quantities of DHW aredrawn off as well as to prematurelystop DHW tank heating if no DHW isdrawn.Coding 55: 3:DHW tank control – DHW heating (forDHW loading systems only)The DHW tank goes cold(set value -4.5˚F / –2.5˚C, adjustablevia coding address 59), The common set supply temperatureis adjusted 36˚F / 20˚C higher thanthe set DHW temperature (adjustablevia coding address 60). The primary DHW pump is switchedON. The three-way mixing valve opensand then regulates to the defaultedset value. The DHW pump cycles (short termON and OFF) until the set supplytemperature has been reached, thenit runs constantly. If, during DHWtank heating, the actual value staysbelow the required set supplytemperature, then the DHW pumpwill temporarily cycle again.The DHW tank is hot(1 st DHW tank temperature sensor:Actual value ≥ set valueand2 nd DHW tank temperature sensor:Actual value > set value -2.7˚F /–1.5˚C) The common set supply temperatureis returned to the weathercompensatedvalue; The DHW pump:– is immediately switched OFF, if thethree-way mixing valve is openor– is switched OFF after run-on timeadjustable via coding 62.5414 553 v1.467
