If a fault occurs during operation, a fault code (e.g. EH b3)

the system components for fault codes not listed here.
The wired room controller may display a different fault code to

8 Environmental protection and disposal
Environmental protection is a fundamental corporate strategy
of the Bosch Group.
The quality of our products, their economy and environmental
safety are all of equal importance to us and all environmental
protection legislation and regulations are strictly observed.
We use the best possible technology and materials for
protecting the environment taking account of economic
considerations.
Packaging
Where packaging is concerned, we participate in country-
specific recycling processes that ensure optimum recycling.
All of our packaging materials are environmentally compatible
and can be recycled.
Used appliances
Used appliances contain valuable materials that can be
recycled.
The various assemblies can be easily dismantled. Synthetic
materials are marked accordingly. Assemblies can therefore be
sorted by composition and passed on for recycling or disposal.
Old electrical and electronic appliances
This symbol means that the product must not be
disposed of with other waste, and instead must be
taken to the waste collection points for treatment,
collection, recycling and disposal.
The symbol is valid in countries where waste
electrical and electronic equipment regulations apply, e.g.
"European Directive 2012/19/EC on old electronic and
electrical appliances". These regulations define the framework
for the return and recycling of old electronic appliances that
apply in each country.
As electronic devices may contain hazardous substances, it
needs to be recycled responsibly in order to minimize any
potential harm to the environment and human health.
Furthermore, recycling of electronic scrap helps preserve
natural resources.
For additional information on the environmentally compatible
disposal of old electrical and electronic appliances, please
contact the relevant local authorities, your household waste
disposal service or the retailer where you purchased the
product.

Batteries
Batteries must not be disposed together with your household
waste. Used batteries must be disposed of in local collection
systems.
