d5 on Remeha Avanta Plus 18s System

Your boiler has temporarily paused heating because the radiators are already as hot as the temperature you asked for, but it will automatically turn back on in a few minutes once it cools slightly.

Monitor it

This is a minor fault. Keep an eye on it and mention it at your next annual boiler service. Reset the boiler and see if it clears.
