10 Spare parts
10.1
Procuring spare parts
The original components of the product were also certified
by the manufacturer as part of the declaration of conformity.
If you use other, non-certified or unauthorised parts during
maintenance or repair work, this may void the conformity of
the product and it will therefore no longer comply with the
applicable standards.
We strongly recommend that you use original spare parts
from the manufacturer as this guarantees fault-free and safe
operation of the product. To receive information about the
available original spare parts, contact the contact address
provided on the reverse of these instructions.
▶
If you require spare parts for maintenance or repair
work, use only the spare parts that are permitted for the
product.
10.2

Disposing of the outdoor temperature
sensor if defective
Note
The outdoor temperature sensor has a reserve
power supply lasting approximately 30 days. Dur-
ing this time the outdoor temperature sensor will
continue to send radio signals even if defective. If
the outdoor temperature sensor is defective and
within range of the radio receiver unit, the radio
receiver unit will receive signals from the defective
yet intact outdoor temperature sensor.
