Commissioning 

The commissioning and matching of the 

control unit to local conditions and building 

characteristics, as well as instructing 

the user in the operation of the system, 

must be carried out by your heating contractor. 

As the user of new combustion equipment, 

you may be obliged to notify your 

local flue gas inspector of the installation 

[check local regulations]. Your local flue 

gas inspector will also inform you [where 

appropriate] about work he may be 

required to perform on your combustion 

equipment (e.g. regular checks, cleaning). 

Your system is preset at the factory 

The control unit is factory-set to "Heating 

and DHW". 

Your heating system is therefore ready 

for use: 


■ Between 6:00 and 22:00 h, the rooms 

are heated with 20 °C "Set room 

temp" (standard heating mode). 

■ Between 22:00 and 6:00 h, the rooms 

are heated with 3 °C "Set reduced 

room temp" (reduced heating mode, 

frost protection). 

■ Your heating contractor can make further 

settings for you during commissioning. 

You can change any settings individually 

at any time to suit your requirements 

(see chapter "Central heating"). 

DHW heating 

■ Between 5:30 and 22:00 h, the DHW 

is heated to 50 °C "Set DHW temperature". 

Any installed DHW circulation 

pump is ON. 

■ Between 22:00 and 05:30 h, the DHW 

cylinder temperature will not be reheated. 

Any installed DHW circulation 

pump is OFF. 

■ Your heating contractor can make further 

settings for you during commissioning. 

You can change any settings individually 

at any time to suit your requirements 

(see chapter "DHW heating"). 

Frost protection 

■ Your boiler and DHW cylinder are protected 

against frost. 

Wintertime/summertime changeover 

■ This changeover is automatic. 

Time and date 

■ The day and time were set by your 

heating contractor during commissioning. 

5592 682 GB

Your system is preset at the factory (cont.) 


Power failure 

■ All data is saved if there is a power 

failure. 

Terminology 

To provide you with a better understanding 

of the functions of your control unit, 

the appendix contains the chapter "Terminology" 

(see page 44). 

Tips on saving energy 

Utilise the setting options for the control 

unit and remote control (if installed): 

■ Never overheat your rooms. Every 

degree by which the room temperature 

is reduced saves up to 6 % on heating 

costs. 

Never set your room temperature 

higher than 20 °C (see page 18). 

■ Never set the DHW temperature too 

high (see page 25). 

■ Only activate the DHW circulation 

pump for times when DHW is drawn 

off. Set the time program for this (see 

page 27). 

■ Select the heating program that meets 

your current requirements: 

– For short absences (e.g. shopping 

trips), select "Economy mode" 


As long as economy mode is activated, 

the room temperature is 

reduced. 

– If you are going away, set the "Holiday 

program" (see page 23). 

As long as the holiday program is 

activated, the room temperature is 

reduced and DHW heating is off. 

– In summer, when you don't want to 

heat any rooms but do need DHW, 

select the heating program "Only 

DHW" (see page 25). 

5592 682 GB 

7


Tips on saving energy (cont.) 

In conjunction with a solar thermal 

system: 

DHW heating is set at the factory to 

start at 05:30 h. On sunny days, the 

DHW cylinder receives sufficient 

heat from the solar thermal system 

that the DHW temperature is still 

high enough the next morning. You 

can program DHW heating to start at 

10:00 h, for example. 

– If you don't want to heat the rooms 

and you don't require DHW for an 

extended period, select the heating 

program "Standby mode" (see 

page 16). 

For additional energy saving functions of 

the control unit, please contact your 

heating contractor. 

Further recommendations: 

■ Correct ventilation/airing. 

Briefly open windows fully and at the 

same time close the thermostatic radiator 

valves. 

■ Close roller shutters (if installed) at 

dusk. 

■ Set thermostatic valves correctly. 

■ Never cover radiators or thermostatic 

valves. 

■ Controlled DHW consumption: A 

shower generally uses less energy 

than a full bath.

Setting the time program for DHW heating 

■ The time program for DHW heating is 

made up of time phases. One time 

phase from 5:30 to 22:00 h for every 

day of the week is set at the factory. 

■ Automatic mode is set at the factory 

for DHW heating. This means that, in 

standard heating mode, the DHW is 

reheated to the set temperature. To 

ensure that hot water is available at 

the start of standard heating mode, the 

time phase for DHW heating begins 

automatically half an hour earlier than 

the time phase for standard heating 

mode.

Maintenance 

Maintenance 

Cleaning 

You can clean the surface of the programming 

unit with a microfibre cloth. 

All equipment can be cleaned with a 

commercially available domestic cleaning 

agent (non-scouring). 

Inspection and maintenance 

Inspection and maintenance of your 

heating system is prescribed by the 

Energy Savings Order and DIN 4755, 

DVGW-TRGI 2008 and DIN 1988-8. 

Regular maintenance ensures troublefree, 

energy efficient, environmentally 

responsible and safe heating. Your heating 

system must be serviced by an 

authorised contractor at least every 

2 years. For this, we advise you to 

arrange an inspection and maintenance 

contract with your local heating contractor. 

Boiler 

Increasing boiler contamination raises 

the flue gas temperature and thereby 

increases energy losses. For that reason, 

all boilers should be cleaned annually. 

DHW cylinder (if installed) 

The DIN 1988-8 and EN 806 specify that 

maintenance and cleaning should be 

carried out no later than two years after 

commissioning and thereafter as 

required. 

Only a qualified heating contractor 

should clean the inside of a DHW cylinder 

and the DHW connections. 

Refill any water treatment equipment 

(e.g. a lock or injection system) in good 

time, if such equipment is installed in the 

cold water supply of the DHW cylinder. 

Observe the manufacturer's instructions. 

Additionally for a Vitocell 100: 

We recommend that the correct function 

of the sacrificial anode is checked annually 

by your heating contractor. 

The anode function can be checked without 

interrupting the system operation. 

The heating contractor will check the 

earth current with an anode tester. 

Safety valve (DHW cylinder) 

The safety valve function should be 

checked every six months by venting, 

either by the system user or the local 

heating contractor. The valve seat may 

become contaminated (see the valve 

manufacturer's instructions). 

Potable water filter (if installed) 

To maintain high hygienic standards, 

proceed as follows: 

■ Replace filter element on non-back 

flushing filters every six months (visual 

inspection every two months). 

■ On back flushing filters, back flush 

every two months.

Appendix 

Ordering fuel oil 

Fuel oil quality 

Vitoladens are approved for the combustion 

of low sulphur fuel oil to DIN 51603- 

EL-1 (max. sulphur content 50 ppm). 

A condensate neutralising system is not 

required (according to Code of Practice 

ATV-DVWK-A 251 [Germany]) when 

using this low sulphur fuel. 

Fuel oil additives 

Fuel oil additives are materials that can 

be used providing they offer the following 

characteristics: 

■ Improvement of stability during fuel 

storage. 

■ Improvement of the thermal stability of 

the fuel. 

■ Reduction of odour development during 

filling. 

Please note 

! Fuel oil additives can create residues 

and impair the safe operation 

of your heating system. 

The use of fuel oil additives that 

leave residues is not permissible. 

Combustion improvers 

Combustion improvers are additives for 

optimising fuel oil combustion. 

Viessmann oil burners do not require 

combustion improvers, as these burners 

operate with clean and efficient combustion. 

Please note 

! Combustion improvers can create 

residues and impair the safe 

operation of your heating system. 

The use of combustion improvers 

that leave residues is not permissible. 

Biofuels 

Biofuels are made from vegetable oil, 

e.g. sunflower or rapeseed oil. 

Please note 

! Biofuels can lead to damage on 

Viessmann oil burners. 

Their use is not acceptable. 

If in doubt refer to your local heating contractor.

Terminology 

Setback mode (reduced heating 

mode) 

See "Reduced heating mode". 


The heating program determines 

whether you heat your rooms and DHW, 

or only heat DHW, or whether you shut 

down your heating system with frost protection 

monitoring. 

You can select the following heating programs: 

■ "Heating and DHW" 

The rooms are heated and DHW is 

provided (winter mode). 

■ "Only DHW" 

DHW is provided but there is no central 

heating (summer mode). 

■ "Standby mode" 

Frost protection for the boiler and the 

DHW cylinder is enabled, no central 

heating, no DHW heating. 

5592 682 GB 

44

Appendix 

Terminology (cont.) 

Note 

No heating program is available for central 

heating without DHW heating. When 

you want central heating, hot water is 

generally also required (winter mode). 

If you do want just central heating, select 

the heating program "Heating and 

DHW" and set the DHW temperature to 

10 °C (see page 28). This means that 

you will not heat DHW unnecessarily but 

the DHW cylinder is protected against 

frost. 

Operating status 

In the heating program "Heating and 

DHW", the operating status changes 

from "Standard heating mode" (see 

page 47) to the operating status 

"Reduced heating mode" (see 

page 48) and vice versa. The times for 

the operating status change are defined 

when the time program is set. 

Extension kit for heating circuit with 

mixer 

Assembly (accessory) for controlling a 

heating circuit with mixer. 

See "Mixer". 

Heating curve 

Heating curves illustrate the relationship 

between the outside temperature, room 

temperature (set value) and boiler water 

or (heating circuit) flow temperature. The 

lower the outside temperature, the 

higher the boiler water or (heating circuit) 

flow temperature. 

In order to guarantee sufficient heat and 

minimum fuel consumption at any outside 

temperature, the conditions of your 

building and your heating system must 

be taken into consideration. The heating 

curve is set by your heating contractor 

for this purpose. 

Note 

If your heating system includes heating 

circuits with mixers, then the flow temperature 

for the heating circuit without 

mixer is higher by a selected differential 

than the flow temperature for the heating 

circuits with mixer. 

The illustrated heating curves apply with 

the following settings: 

■ Heating curve level = 0 

■ Standard room temperature (set 

value) = 20 ºC

Heating circuit 

A heating circuit is a sealed circuit 

between the boiler and radiators, in 

which the heating water circulates. 

A heating system may comprise several 

heating circuits. For example, one heating 

circuit for the rooms occupied by you 

and one heating circuit for the rooms of 

a separate apartment. 

Heating circuit pump 

Circulation pump for the circulation of the 

heating water in the heating circuit. 

A mixer mixes the water heated in the 

boiler with the cooled water returning 

from the heating circuit. The water, 

heated to the right temperature in line 

with demand, is delivered to the heating 

circuit by the heating circuit pump. The 

control unit adjusts the heating circuit 

flow temperature via the mixer to the various 

conditions, e.g. different outside 

temperature. 

Night setback 

See "Reduced heating mode". 

Standard heating mode 

When you are in the house during the 

day, you can heat the rooms in standard 

heating mode. Set the periods using the 

time program for central heating. During 

these times, the rooms are heated to the 

standard room temperature. 

Standard room temperature 

Set the standard room temperature 

when you are at home during the day 


Open flue operation 

The combustion air is drawn from the 

room where the boiler is installed. 

47

Appendix 


Balanced flue operation 

The combustion air is drawn from outside 

the building. 

Reduced heating mode 

When you are out or during the night, you 

can heat the rooms in reduced heating 

mode (setback mode). Set the periods 

using the time program for central heating. 

During these times, the rooms are 

heated to a reduced room temperature. 

Reduced room temperature 

When you are out or during the night, set 

the reduced room temperature (see 

page 18). See also "Reduced heating 

mode". 

Safety valve 

A safety device that must be installed by 

your heating contractor in the cold water 

pipe. The safety valve opens automatically 

to prevent excess pressure in the 

DHW cylinder. 

Solar circuit pump 

In conjunction with solar thermal systems. 

The solar circuit pump delivers the 

cooled heat transfer medium from the 

DHW cylinder indirect coil to the collectors. 

Set temperature 

Default temperature that should be 

reached; e.g. set DHW temperature. 

Summer mode 

Heating program "Only DHW". 

At warmer times of the year, i.e. when 

the rooms do not have to be heated, you 

can stop heating mode. The boiler 

remains enabled for DHW heating. 

Cylinder primary pump 

Circulation pump for heating the DHW in 

the DHW cylinder. 

Potable water filter 

A device that removes solids from the 

water. The potable water filter is installed 

in the cold water pipe upstream of the 

DHW cylinder or the instantaneous 

water heater. 

Weather-compensated mode 

In weather-compensated mode, the 

heating flow temperature is controlled 

according to the outside temperature. 

This means that no unnecessary heat is 

generated in order to heat the rooms to 

the set room temperature you selected. 

The outside temperature is captured and 

transmitted to the control unit by a sensor 

fitted outside the building. 

DHW circulation pump 

The DHW circulation pump transfers the 

hot water around a circuit between the 

DHW cylinder and the draw-off points 

(e.g. hot tap). This makes hot water 

available quickly at the draw-off point.
