Powering up my new Vaillant which was installed earlier this year, so just testing ahead of the season.  So I have set INACTIVE as I wanted to run full weather compensation (so NO influence of any temperature controllers).  And as a test today I set a weekly planner for the HP to run for 2hours between 2pm and 4pm.  It came on at 2pm but didn't turn off at 4pm.

So when running pure weather comp, is the weekly planner NOT active?  Screen prints of my set up attached.

(PS note.  Only trying to running a time schedule such that I can use overnight peak rates, house only needs 4/5 hours a day/night in the shoulder months, so will run 24/7 once winter is here.)
