available domestic cleaning agent (non-scouring).
You can clean the front 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.
Regular maintenance ensures trouble free, energy
efficient, environmentally responsible and safe heating.
Your heating system must be serviced by an authorized
contractor at least every 2 years. For this, we advise you
to arrange an inspection and maintenance contract with
your local heating contractor.

Terminology

Heating program
With the heating program you determine whether the
boiler is available for heat production to the Vitotronic
300-K MW2C or if the boiler is in standby with frost
protection active.
You can select the following heating programs:
H "Heating"
The boiler is available to the Vitotronic 300-K for heat
production.
H "Standby mode"
Frost protection for the boiler.
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
boiler temperature.
18 18
Boiler
Increasing boiler contamination raises the flue gas
temperature and thereby increases energy losses.
For that reason, all boilers should be cleaned annually.
Damaged connecting cables
If connecting cables of the appliance or externally
installed electrical accessories are damaged, replace
them with special connecting cables. Replace only with
Viessmann cables. Contact your local heating contractor.
Room air dependant operation
The combustion air is drawn from the room where the
boiler is installed.
Direct vent 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 tank.
Set temperature
Default temperature that should be reached;
e.g. set boiler temperature.
