Nibe furnace display shows normal operation but room remains too hot

Safety: Avoid setting very low flow temperatures in freezing conditions without proper frost protection.

• Relocate room sensor: Move the sensor away from drafts, sunlight, and heat sources so it measures average room temperature.
• Lower heating curve: In the Nibe menu, reduce the heating curve slope and/or offset gradually until comfort improves.
• Check zone valves: Ensure any motorized valves close properly when there is no heat demand.
