[esp-r] control bug?

[Stephan Schlitzberger]

Hello esp-r-users,
 
something strange happens to the (weekend-) controls at the beginning of
each day (Saturday, Sunday and Monday)
.
In the picture attached you can see the simulation results of the air
temperature of a 100% temperature controlled zone. I used the maximum number
of 8 controlperiods for each day type. Each is 3 hours long and controlled
by a basic controller for heating/cooling.
When you take a look at the picture, you see that at the beginning of each
day the first hour during the first determined 3-hour-period from 0.00 to
3.00 doesn´s behave as it shoud. During this first hour you find exactly the
temperature belonging to the corresponding control-period from the day
before from 0.00 to 3.00. 
Obviously this behaviour doesn´t occure during weekdays. At the beginning of
the 4th day the first 3-hour-period (from 72 to 75) has one constant
temperature

 
??? does anybody know what the reason for this could be, or is it really a
bug?
 
Best regards
Stephan Schlitzberger
