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 carry out on your combustion equipment (e.g. regular checks, cleaning).
Your system is preset at the factory
The control unit is factory-set to " for central heating and DHW heating.
"
Your heating system is therefore ready for use:
Central heating
■ The rooms are heated in accordance with the settings on your control unit and room temperature control unit.
■ 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
■ The DHW is heated to 50 °C.
■ 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.
Power failure
■ All data is saved if there is a power failure.

Tips on saving energy
Utilise the setting options on the control unit and the room temperature control unit:
■ 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 12).
■ Never set the DHW temperature too
■ Select the heating program that meets your current requirements:
– In the summer, if you do not want to heat any rooms but require hot water, select the " " heating pro-
– If you do not want to heat any rooms and require no hot water for a prolonged period of time, select the
" " heating program (see
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.

Maintenance
Maintenance
Cleaning
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 strongly 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. All boilers should therefore 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.
You can clean the front of the programming unit with a microfibre cloth.
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.
In this connection, 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 hygiene 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.
28
Terminology
Constant temperature operation
In constant temperature operation, the heating water is constantly heated to the selected boiler water temperature.
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:
■ "
"
The rooms are heated and DHW is provided (winter mode).
■ " "
DHW is provided but there is no central heating (summer mode).
■ " "
Frost protection for the boiler and
DHW cylinder is active, no central heating, no DHW heating (standby mode).
Note
A heating program for central heating without DHW heating is not available. If rooms are to be heated, hot water is generally also required (winter mode).
If you still only want central heating, select the " " heating program and set the DHW temperature to 10 °C (see
page 15). This means that you will not
heat DHW unnecessarily but the DHW cylinder is protected against frost.
Heating circuit
A heating circuit is a sealed circuit between the boiler and radiators, in which the heating water circulates.
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.
Boiler water temperature
See "Constant temperature operation".
Open flue operation
The combustion air is drawn from the room where the boiler is installed.
Balanced flue operation
The combustion air is drawn from outside the building.
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.
Set temperature
Default temperature that should be reached; e.g. set DHW temperature.
29
Terminology
(cont.)
Summer mode
Heating program " ".
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.
