Reading from Met Éireann stations around the house (median of three), recorded hourly by your home.
When it is this warm outside, rooms do not call the boiler at all. Radiator valves keep their targets; hot water is never affected.
Warmer rooms on cold days, or cooler on mild ones: each rule adds or takes away a few degrees from the scheduled temperature in the rooms you pick, while the outside temperature meets its condition. Rules never touch a hold, Away or Heating Off, and the room's safe range still applies.
The sunrise/sunset option for schedule changes is on the Heating schedule page.
