Todd,
One way to do this is to set up a global parameter value for the hours
between 6 & 10 and change those parametrically. So you wouldn't be
varying the setback hour, but rather the temperatures at the time
between those hours. Not the cleanest way to do it, but it works.

Subject: NINJA-SPAM:[Equest-users] User Expressions in Schedules eQuest
Is there a way to modify day schedules using global parameters. For
example, say I want to compare the difference between having a setback
start at 6 pm instead of 10 pm. I know how to create two different
schedules and change them in the parametric run to get the difference.
However, let's say I want to use a single schedule to save time if I
want to run many different parametric runs. In pseudo code, I would say
something like-
Global parameter - Setback Hour (6 pm or 10 pm)
If time < "Setback Hour", then cooling setpoint is 72, else cooling
setpoint is 80
There would be a similar code to bring the setpoint back to occupied.
Is it at all possible to create a User expression in the schedules that
would to this? I could not find a keyword that corresponds to a time of
day, so I think this all may be in vain.
Thanks,
Todd
