Environmental protection and disposal
Environmental protection is a fundamental corporate strategy
of the Bosch Group.
Thermostat and receiver communication error
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.
After the communication connection has been disconnected
for 350 seconds, the red LED of the receiver will flash fast and
slowly alternately.
The cause of the failure may be the distance between the
thermostat and the receiver, wireless frequency conflicts or low
batteries in the thermostat.
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.
•
When the receiver is reconnected to the thermostat, the
receiver will automatically switch to the normal working
mode.
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.
•
When the communication is disconnected, the receiver will
automatically turn OFF the heating in the boiler. This
function effectively avoids energy waste and safety issues
when the communication is disconnected in winter mode.
When the communication between the receiver and the
thermostat is disconnected, the heating can be turned ON
manually in the button on the receiver. The green LED will
flash fast and slowly alternately. Once the wireless
communication is reconnected, the receiver will work
according to settings of the thermostat.
•
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.
•
•
If the receiver is installed too far from the thermostat, the
wireless communication may be weakened. After the
communication is disconnected for a period of time, it can
be restored to the normal working mode.
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.
When the power supply of the receiver is insufficient, the
communication connection will fail. The receiver will be in
standard working mode after the power supply is
recovered, and it will work according o settings of the
thermostat. It is not necessary to perform any operation to
the thermostat or the receiver, unless the location of the
thermostat is changed.
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.
Thermostat real-time temperature deviation
If deviation between thermostat real-time temperature and
actual temperature exceeds 1.5℃, the thermostat needs to be
calibrated.
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.
For consulting the calibration method, check parameter P03.

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