1.3 INSTALLATION INFORMATION

As these products communicate using RF technology special
care must be taken during installation. The location of the RF
components as well as the building structure may influence
performance of the RF system. To assure system reliability,
please review and apply the information given below.
Within a typical residential building the two products should
communicate reliably within a 30m range.
It is important to take into consideration that walls and ceilings
will reduce the RF signal. The strength of the RF signal
reaching the RF Receiver depends on the number of walls and
ceilings separating it from the Room Thermostat, as well as the
building construction. Walls and ceilings reinforced with steel
or plasterboard walls lined with metal foil reduce the RF signal
significantly more.
