1.1 Intended use
In the event of inappropriate or improper use,
damage to the product and other property
may arise.
The product is intended for using an eBUS
interface to control a heating installation with
heat generators from the same manufacturer.
The radio control, the radio receiver unit and
the wireless outdoor temperature sensor
must be installed in a location that receives
sufficiently high signal. The radio control is
not intended to be portable.
Intended use includes the following:
– observance of accompanying operating,
installation and servicing instructions for
the product and any other system compon-
ents
– installing and fitting the product in accord-
ance with the product and system approval
– compliance with all inspection and main-
tenance conditions listed in the instruc-
tions.
Intended use also covers installation in ac-
cordance with the IP class.
Any other use that is not specified in these
instructions, or use beyond that specified in
