Special care must be taken during installation with product that communicates using RF technology.
The location of the RF components as well as the building structure may influence performance of the RF
system.
Within a typical residential building the two products should communicate reliably within a 30m range. It is
important to take into consideration that wall and ceilings will reduce the RF signal. The strength of the RF
signal reaching the relay box depends on the number of walls and ceilings separating it from the room
thermostat, as well as the building construction – see

signal significantly more.
