[EnergyPlus_Support] RE: Your input file
Thank you for your help, Linda.
Well, changing the zone mixer outlet fixed the problem with the data, but
now it seems there is something wrong with the controls. The ac is cooling
the zones to 15 C at night. Shouldn't the heat have kicked on by then?
As far as I know the set point schedules are okay. Heating is set at 20 C
during the day and 15 C at night, and cooling is 24 C day and 30 C night.
Even with this there is cooling in the plenums (around 8 C). Am I
specifying this wrong?

Sorry we're not figuring things out so well. Perhaps we have become more
popular recently, we seem to be swamped in questions! And clean up from
being gone, of course.
