Salus ERT20RF Ver010_89 12/03/2014 10:05 Page 9 TESTING THE RF TRANSMISSION It is important to site both the receiver and thermostat in locations where the RF signal cannot be interrupted. The receiving range between thermostat and receiver is approximately 30 metres indoors, however many factors can affect the RF transmission and shorten the operating distance, e.g. shielding by thick walls, foil back plasterboard, metal objects such as filing cabinets, general RF interference, and so on.

The red led below the dial will glow. When the correct temperature has been reached then the LED will go out. If LED is flashing continuously in normal operation then the batteries need replacing.
