Introductory information
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 "Heat-
ing and DHW".
Your heating system is therefore ready for use:
Central heating
■ Between 6:00 and 22:00 h, the rooms are heated at 20 °C "Set room tem-
perature" (standard heating mode).
■ Between 22:00 and 6:00 h, the rooms are heated at 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 temper-
ature". 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.

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 so 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
For additional control unit energy saving functions, please contact your heating contractor.
Further recommendations:
■ Correct ventilation/airing.
Briefly open windows fully and at the same time close the thermostatic 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.

DHW heating
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.
■ If you don't want the automatic mode, you can select up to 4 individual time phases per day for DHW heating, which can be the same for every day of the week or different. Set the start and end points for each time phase.
■ When setting, bear in mind that your heating system requires some time to heat the DHW to the required temperature.
■ In the "Extended menu", you can scan the current time program under "Infor-
mation" (see chapter "Scanning information", "DHW" group).

Cleaning
All equipment can be cleaned with a commercially available domestic cleaning agent (non-scouring). Clean the surface of the programming unit with a microfibre cloth.
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.

Ordering fuel oil
Fuel oil quality
Vitoladens appliances 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.
■ Increase in 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 rape seed 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.

Building drying
Your heating contractor can, for example, enable the "Screed function" for your new installation or fitting for building drying. With the screed function, your screed is dried in line with the building material according to a fixed time program (temperature/time profile).
53
Appendix
Terminology
(cont.)
The screed function affects the heating circuits with a mixer:
■ All rooms are heated according to the temperature/time profile.
Your settings for central heating have no effect for the duration of the building drying.
■ DHW heating is carried out (but priority control is cancelled).
Heating program
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.
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 chapter "Setting the DHW temperature"). This means that you will not heat DHW unnecessarily but the
DHW cylinder is protected against frost.
54
Operating status
In the heating program "Heating and
DHW", the operating status changes from "Standard heating mode" (see
page 56) to the operating status
"Reduced heating mode" (see
page 57) 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.

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 temperature 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.

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.
Actual temperature
Current temperature at the time of the scan; e.g. actual DHW temperature.
Mixer
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
(see chapter "Setting the room temperature").

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 chapter "Setting the room temperature").
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 disable 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 drinking 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.
