Adjusting the heating curve (Vitocontrol-S, WB2B)
The heating curves illustrate the relationship between the outdoor temperature and the boiler water or the supplytemperature. To put it simply: the lower the outdoor temperature, the higher the boiler water or supply temperature. Theroom temperature again depends on the boiler water or the supply temperature.
Factory default settings:Slope: = 1.4Shift: = 0
Generally, the heating curve is set:In range A for underfloor heating systems,In range B for low temperature heating systems (according to the Energy Savings Order),

Functions
The boiler water temperature isrecorded separately:Fixed high limit (FHL)Boiler temperature sensor KTS(changes in resistance NTC)
Upper control limit.Electronic maximum limitSetting range: 20 to boiler coding carddefaultThe maximum boiler water temperaturelimit can be adjusted via codingaddress 06.
Control sequence
Boiler goes cold
(set value 4ºC below set point)The burner start signal is set to the setboiler water temperature less (=less7.2ºF or 4ºC) and the burner starts itsown monitoring program.
Note:
Value on display shown in K (Kelvin).
1 K = 1.8 Fahrenheit degrees or 1

Cascade control unit
Brief description
The 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 the
cascade control
35 to 3F, 41 to 4F.For a description, see the codingoverview.
Set supply temperature
The 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 limit
Electronic 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 limit
Electronic minimum system supplytemperature limit.Setting range: 68 to 261˚F / 20 to127˚C.The minimum supply temperature limitcan be adjusted via coding address 36.

Function description – Vitocontrol-S, WB2B
Cascade control (continued)
Control sequence
Stand-alone type of control: Parallel boiler control
(coding 3b : 0 without supply temperature sensor or
coding 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.
With supply temperature sensor:
The contro deviation is calculated fromthe set supply temperature and theactual supply temperature to determinethe start-up and shutdown criteria.
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.
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 criterion
Boilers 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 times
Shutdown criterion
The boiler is shut down via a shutdownintegral. The shutdown criterion is metwhen the shutdown integral exceeds alimit set via coding address 46, and theboiler started last will be shut down.
5414553v1.8
60
Function description – Vitocontrol-S, WB2B
Cascade control (continued)
Net calorific strategy 1
Conventional boilers are preferablyoperated at their upper output range, toreliably prevent the formation ofcondensate due to low returntemperatures.With net calorific strategy 1, anadditional boiler will only be started ifthe maximum output of all currentlyactive burners is insufficient to achievethe set supply temperature.A boiler will be shut down, when theremaining boiler(s) can achieve therequired output on its/their own.
Benefit:As few boilers as possible are active.
Start-up criteria
The boiler is started via a start-upintegral.The start-up criteria is met when thestart-up integral exceeds a limit set viacoding address 45, and the next boilerin the sequence will be started (seepage 62).
Shutdown criteria
The boiler is shut down via an outputstatement (coding 3d: 1).A boiler is shut down when thecurrently required output can beachieved without the boiler which wasstarted last.
Net calorific strategy 2
With the net calorific strategy 2, anadditional boiler will only be started ifthe maximum output of all currentlyactive burners is insufficient to achievethe set supply temperature.A boiler will be shut down if the burnerwas returned to its minimum outputbecause of a large negative controldeviation, and the output is then stilltoo high.
Benefit:Long burner operating times
Start-up criteria
The boiler is started via a start-upintegral.The start-up criteria is met when thestart-up integral exceeds a limit set viacoding address 45, and the next boilerin the sequence will be started (seepage 62).

Heating circuit control
Brief description
The control unit provides controlcircuits for one high temperature(boiler) circuit and two mixing valvecircuits.The set supply temperature of everyheating circuit results from the outdoortemperature, the set room temperature,the operating mode and the heatingcurve.The supply temperature of the systemcircuit corresponds to the commonsystem supply temperature.The supply temperature of the mixingvalve circuits is regulated by thestepped opening or closing of themixing valves.The mixing motor control changes theactuating and pause times subject tothe control difference(control deviation).
Coding addresses which influence the
heating circuit control
9F,A2 to A7, A9, C3 to C8, F1, F2For a description, see the codingoverview.
Functions
The high temperature (boiler) circuit issubject to the boiler water temperatureand its control range limits.The heating circuit pump is thecontrolling element. The mixing valvecircuit supply temperature is recordedby the supply temperature sensor.
Time program
The control unit timer changes inaccordance with the times programmedin the room heating and DHW heatingprogram between the heating withnormal room temperature and heatingwith reduced room temperatureoperating modes.Every operating mode has its own setlevel.
Outdoor temperature
A heating curve must be set up formatching the control unit to thebuilding and the heating system.The heating curve characteristicsdetermine the set boiler watertemperature subject to outdoortemperature. An average outdoortemperature (dampened) is used forcontrol purposes. This comprises theactual and the adjusted outdoortemperature.

Heating circuit pump logic
(economy circuit)
The heating circuit pump is switchedOFF (set supply temperature set to 0˚C /32˚F), when the outdoor temperatureexceeds the value selected via codingaddress A5.
Extended economy circuit
The heating circuit pump is switchedOFF, and the set supply temperature isset to 32˚F / 0˚C, if:The outdoor temperature exceeds thevalue selected via coding address A6.
The set room temperature is reducedvia coding address A9.
In conjunction with the mixing valvecircuit:The mixing valve has been closed for12 minutes (mixing valve economyfunction, coding address A7).
Slab curing function
(only in conjunction with a mixing valvecircuit).
Please note:
Four different temperature profiles canbe selected for drying the slab. Theseprofiles are activated via codingaddress F1.
When the slab curing function isactivated, the heating circuit pump ofthe mixing valve circuit is switchedON, and the supply temperature will beheld at the selected profile. Aftercompletion (30 days), the mixing valvecircuit will be regulated automaticallyvia the set parameters.
System dynamics – mixing valve circuit
(only in conjunction with a mixing valvecircuit)
You can influence the controlcharacteristics of the mixing valve viacoding address C4.
Central operation
Central operation for all downstreamheating circuits can be programmed viacoding address 7A.The heating and holiday program thenapplies to all heating circuits in thesystem.The programming unit of the otherheating circuits displays central controlwhen the heating program and holidayprogram buttons are activated.Any set holiday programs in theheating circuit programming units willbe deleted.
Party and economy buttons on all
control units are without effect.
Frost protection
When the outdoor temperature fallsbelow 34˚F / 1˚C, a supplytemperature of at least 50˚F / 10˚Cwill be safeguarded.For changes, see coding address A3,variable frost limit.

DHW tank control
54 to 75, 7F, A2.For a description, see the codingoverview.
Functions
Time program
An 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.
In conjunction with coding address 7F
7F: 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.
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 priority
With 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 protection
The DHW tank will be heated to 68˚F /20˚C, if the DHW temperature fallsbelow 41˚F / 5˚C.
Auxiliary functions – DHW heating
This function is activated by providinga second set DHW temperature viacoding address 58 and activating the4th DHW phase for DHW heating.
Set DHW temperature
The set DHW temperature can beadjusted between 50 and 140˚F / 10and 60˚C. The set range can beexpanded to 203˚F / 95˚C via codingaddress 56.You can select the set DHWtemperature at the programming unit ofthe control and at every Vitotrol 300remote control unit (if installed).You can determine the allocation toindividual heating circuits via codingaddress 66.
DHW recirculation pumpIt delivers hot water to the draw-offpoints at adjustable times. Up to fourcontrol periods can be set at the timer.
Auxiliary circuits
The DHW heating can be disabled orenabled by changing over the heatingprogram.
System with DHW tank heating system
The above functions also apply inconjunction with calorifiers.Set the following codings:4C: 1, 4E: 1, 55: 3.For a description, see the codingoverview.
Systems with Vitosolic
A third DHW temperature set-point canbe programmed via coding address 67.Reloading suppression will be activebelow the set temperature. The DHWtank is heated only by the solar heatingsystem.

DHW tank temperature control (continued)
Control sequence
Pump delay
The DHW pump continuous operation(coding 62: 10) after the DHW tankheating, until:– the actual temperature is 9˚F / 5˚Chigher than the set DHWtemperature or
– the maximum time delay (adjustablevia coding address 62) has beenreached.
Without the pump time-delay forDHW tank heating (coding 62: 0).
Coding 55: 0:
DHW heating
The DHW tank goes cold
(set value 4.5˚F / –2.5 ˚C, adjustablevia coding address 59)The common supply temperature isadjusted 36˚F / 20˚C higher than theset DHW (adjustable via coding address60).
The DHW tank is hot
(set value +4.5˚F / 2.5˚C)The common set supply temperature isreturned to the weather-compensatedvalue.
Coding 55: 1:
Adaptive DHW tank heating
With adaptive DHW tank heating, thespeed of the temperature rise duringDHW heating is taken into account.Also taken into account is the questionof whether the boiler will be required tosupply heat after the DHW tank hasbeen heated or whether residual boilerheat should be transferred to the DHWtank.Accordingly, the control unitdetermines the burner and DHWrecirculation pump shutdown point toprevent the set DHW temperaturebeing substantially exceeded after theDHW tank has been heated.
Coding 55: 2:DHW tank temperature control with
2 DHW tank temperature sensors
The 1st DHW tank temperature sensorenables the DHW pump, and isevaluated for stop conditions duringthe pump run-on time. The 2nd 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 (for
DHW 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
(1st DHW tank temperature sensor:Actual value ≥ set valueand2nd DHW tank temperature sensor:Actual value > set value -2.7˚F /–1.5˚C)The common set supply temperatureis returned to the weather-compensated value;
The DHW pump:– is immediately switched OFF, if thethree-way mixing valve is openor
– is switched OFF after run-on timeadjustable via coding 62.
