Check the model, note the full code and learn the useful precautions before the diagnosis.
Before reading the list
Selection for the Radson Digital RF thermostat, manual 51042(2). Err in position 6 reports an internal or external sensor fault according to the flashing symbol; Lo and Hi in position 4 indicate lower and upper floor limits. The manual also distinguishes the limiter sensor in position 4 (Er in EN/NL, Err in FR). Identify the position and symbol before interpreting the message. Ordinary hydronic radiators do not display these messages, and this list does not cover older Radson boilers.
