BoilerFaultCodesTechnical description
Do not send time to LON
What causes this fault?
This fault occurs when there is a configuration error in the boiler's communication settings, specifically regarding how it shares time and date information with other linked components. It usually happens because the control system is trying to send a time signal to a network module that isn't set up to receive it, or there is a minor data mismatch between the internal boards.
DIY fix possible
Turn the boiler power off at the fused spur switch.Wait for 30 seconds.Turn the power back on and check if the date and time settings are correct on the display.
