I'm currently wondering why I'm seeing at least one, perhaps two, zones which seem to always come on right at the start of their optimisation period first thing in the day. I have had this set to 2 hours, because I thought why not, if 2 hours are not needed to heat a room, it will simply come on later. But our bedroom always kicks in right at the start of the 2 hours. This morning it only took about 45 mins to reach SP, but it still insisted on coming on early. 30mins after first call for hit the boiler demand was only 12%. (And why is the bedroom TRV always the noisiest ? )

If it had been freezing in the past day or two I would perhaps understand it, but its been relatively mild the past few days.

Am I just being impatient with the self learning? Or is something else going on?
