[esp-r] Problem with zone control

[Grant, Jordan]

Hi all,



I'll try to keep this short. The problem seems to be with the zone control. Initially I had defined a more complex control logic and so I simplified it to see if this solved the problem but had no joy.



Basically,

               - I've changed the calendar days in the model context because I want to implement different control on three days in particular (12/2 - 14/2).

               - In the zone control menu I've defined control for the three days and allowed anything out with this period to free float [See images 2-4, below]

               - I've run a simulation which covers the three day period. See below the sensible heating from the period 12-2-2014 to 15-2-2014. I cannot understand why there is NO heat injected between 0hr and 1hr on the 13th feb or why there IS heat injected between 0hr and 1hr on the 15th feb.

What is also interesting is that I changed the control on the 14th feb back to "freefloating." I would've expected the sensible heating graph to show heat being put in from 10am on the 12th (day type - heat on) until 24 hours on the 13th (day type - steady heat). However the heating appears to be on from 10am - midnight on the 12th and then from 1am on the 13th until 1am on the 14th. I've tried different ways of defining the control but can't seem to fix this.



Please let me know if you have any thoughts on this.



Thanks,



Jordan
