Appliance characteristics
2 Application
Your atmoCRAFT gas heating boiler provides heating
3 for living or business rooms via a hot-water central
heating system.
A storage tank is connected to your boiler for heating
the hot water.
Various controllers are available as Vaillant accessories
for comfortable adjustment of the heating and hot water
3 functions of your boiler.
4 Description of the appliance
- The especially efficient two-stage method of operation
of the gas burner in the atmoCRAFT boilers ensures
low switching frequency and high levels of standard
efficiency.
- Your boiler is fitted with a digital information and
analysis system (DIA-System) for maintenance and
service work by the heating engineer.
The status display provides information on the
operational condition of your boiler. In the event of a
7 fault, the display of diagnosis and fault codes assists
your heating engineer in quickly finding the cause of
the fault.
