Information for 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 help to keep
energy inside the room.
Minimise energy loss through sensible ventilation
Ventilating for hours loses heat stored in walls and objects. As a result, the room
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
radiators 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 uses additional energy.
Sensible handling of DHW
Showering consumes only approx. 1/3 of the water volume required for a bath. Repair
any dripping taps immediately.
If the illuminated ring of the status indicator flashes red, where possible read the fault
code on the connected control unit accessory and note the code. The boiler can be
restarted by pressing the reset button. In case of repeated faults, switch OFF the
boiler and notify your heating contractor.
Oil 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.
Caution - risk of damage, poisoning and suffocation!
