Please note: This product should only be installed by 
a qualified electrician or competent heating installer 
and should be in accordance with the local wiring 
regulations.
Note: These products use RF (Radio Frequency) technology to 
communicate with each other and it is important that care is taken 
during installation to ensure good wireless connection.  Building 
structure and materials may influence performance and large metal 
objects such as boiler cases, appliances or mirrors in line of sight 
between the thermostat and the receiver will prevent communication.
The receiver should be mounted near to the heat source leaving 
a minimum distance of 30cm away from any metal enclosures or 
appliance and positioned so that no large metal obstruction is between 
the receiver and thermostat.  The thermostat can be mounted remotely 
up to 30m from the receiver while considering signal strength will 
be reduce as it passes through walls and ceilings.  Walls and ceilings 
containing steel reinforcement or with metal foil lined insulation will 
also have a significant effect on communication distance and may 
block signal completely. 
It is recommended that the RF connection should be checked 
before permanently mounting the thermostat and where necessary 
the location of the thermostat must be moved to ensure reliable 
communication.  The thermostat should be mounted at a height of 
approximately 1.5m from the floor and away from draughts or heat 
sources such as radiators, open fires or direct sunlight.
