Any luck with getting hold of that Change Log.
Any luck with getting hold of that Change Log.
I'm pretty sure it needs a setpoint change to kick in. I have a bedroom that is currently set at 15C all day over several intervals. The room temp has been constantly above this (currently 19.9) and the controller still shows this as normal schedule following. The room temp has been at least 20C for the last 24 hours.
Another room is set at 16C most of the day but has a short boost in the morning to 20. The boost period should be active (now 8am), the current room temp is 19.5, the controller is showing the room is off with a setpoint of 5C. I think at the setpoint change at the beginning of the boost (7am) the room temp may have been 20C. The room setpoint has been 5C since 1pm yesterday.
The outside temp is currently 7C.
Beta installed late morning day before yesterday.
I currently have other zones in CW boost.
All zones configured for WW.
Neither room described has CW configured.
Both HR92 for temp sensor.
Two questions?
1. Why didn't WW kick in for the first room?
2. What would have happened if the temperature in the second room had fallen more quickly after 7am? I suspect nothing is going to happen.
This morning again an interesting mix of zone behaviour with the new features - really difficult to fathom out if correct or not ??

Something else I spotted yesterday in the installer menu zone config>select zone>parameters>Rate of Rise - have I missed this or is it new and if so is it related to advanced load scaling? Is an adjustable value but random selection of zones all show the same 3C value

SteveP, Since it was hot yesterday, I still have one room that is shut down from last night, due to it not not dropping below the actual SP by 1'C( I think it needs to be this). That room is holding heat still so not dropped below SP so still in hot weather shutdown.. So have a look at your setpoints for the photos you taken. If room temps are 1'C below SP then I do not think the shutdown resets. 1.5'C I believe it resets..
Question about your office... I see the loop symbol which is a permanent overrule of 5'C SP, did you make this permanent overrule, or was that a manual override, because I had a random permanent overrule appear instead of the a manual override I performed.
Well spotted, yes this is new.
As the value is named "Load scaling rate of rise" when you go into it then I'd say yes it's related to load scaling
Mine are all set to 3.0C as well and the range is 0.5C to 6C. This setting will be related to how many degrees C per hour the radiators in a zone can raise the temperature going at full tilt.
When I analysed the optimal start function years ago I came to the conclusion that the controller started off with an assumption of 3C / hour rate of rise for all zones before gradually adapting to the true rate of rise of each zone, (to get the room to hit the target at the right time) with a maximal adaption range of approximately 1-6C / hour. So it's interesting to see a default of 3C here and a similar range of adjustment.
Perhaps Andy can clarify what adjusting this zone setting would do - load scaling is said to be adaptive to the characteristics of each zone (after a week or two of monitoring the zone characteristics to learn) so I'm not sure how a manual adjustment fits in here, and whether altering this value would override any automatic adaption, as there isn't an "auto" setting to return it to after you've manually made a change.
