Note: When the heating is working and within the range shown in the table below
If the thermistor is out of range the boiler will lock out, automatically “resetting” again when
the working range is entered. In case DHW is working the boiler continues work even if the
led
displays fault. The boiler uses the heating t
hermistor to regulate DHW temperature.
