Appliance characteristics
Application
Your atmoCRAFT gas heating boiler provides heating
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
functions of your boiler.
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
fault, the display of diagnosis and fault codes assists
your heating engineer in quickly finding the cause of
the fault.
