CM700 Wireless - Programmable Room Thermostat

1) 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 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.
