energy-efficient operation
Keep the heat inside the room - at night too
At night, closing shutters and drawing curtains noticeably reduces heat losses via the
window areas. Insulating the radiator recesses and light coloured paintwork can save
up to 4 % off your heating bills. Airtight joints at windows and doors also helps to keep
energy inside the room.
Minimise energy losses through sensible ventilation
Ventilating for long periods loses heat stored in walls and objects. Result: The ambient
climate will only become comfortable again after prolonged heating. Short and thorough
airing is more effective and pleasant.
Venting the radiators
Regularly vent the radiators in every room. This safeguards the perfect function of ra-
diators and thermostats, particularly in the upper apartments of apartment blocks. The
radiator responds quickly to changing heat demands.
Intelligent use of DHW circulation pumps
Always control DHW circulation pumps via time switches. Program these in accordance
with your DHW demand patterns.
The optimum DHW temperature
Only ever set the DHW temperature or that of the cylinder to the temperature you really
require. Any additional heating costs additional energy.
Continuous handling of DHW
Showering consumes only approx. 1/3 of the water volume required for a bath. Imme-
diately repair any dripping taps.
If the illuminated ring of the status indicator flashes red, where possible read off the
fault code from the connected controller and note down the code. The boiler can be
restarted by pressing the reset button. In case of a repeated fault, switch OFF the
boiler and notify your heating contractor.
Gas fired condensing boilers are equipped with an electronic flue gas temperature
limiter. The system automatically shuts down when the flue gas temperature exceeds
110 °C. The boiler can be restarted by pressing the reset button. If this recurs, ask
your heating contractor to check the flue gas system.
Please note - risk of damage, poisoning and suffocation.
