Instruction manual

The ideal position to locate the RT505TX thermostat is about 1.5m
above floor level. It should be mounted in a location where the
thermostat is accessible, reasonably lit and free from extremes of
temperature and draughts. Do not mount the thermostat on an
outside wall, above a radiator or in a location where it may be
subjected to direct sunlight.
To ensure trouble free operation of the Radio Frequency (RF)
signal, always ensure that the programmable thermostat is
mounted away from any possible sources of interference (such as
radios, TV sets, computers, etc.), and is not mounted on or in close
proximity to large metal objects. Installing the RT505TX in
enclosed areas such as cellars and basements is not recommended.
