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 Relay Box depends on the number of walls and ceilings separating it from the room thermostat, as well as the building construction - the diagram below illustrates an example of typical signal strength reduction. Walls and ceilings reinforced with steel or plasterboard walls lined with metal foil reduce the RF signal significantly more. Once a position is selected for the room thermostat this can be checked using the RF Communication Test mode as described in section 2.2.3 Locating the Room Thermostat. If the position is unsuitable the Relay Box will not respond and an alternative position must be selected. = Signal Strength Wall Wall Wall Ceiling Max.
