When I try the run OS model which used to run straight in OS 2.4.0 in OS 2.5.0 I get the E+ warnings:

** Warning ** ProcessScheduleInput: Schedule:Day:Interval="2LLO TUESDAY", Values are outside of range for Schedule Type Limits Name=FRACTIONAL

And finally I get the E+ severe :

   ** Severe  ** ProcessScheduleInput: Schedule="2ND LIVING LIGHT USAGE" has values outside its Schedule Type (FRACTIONAL) range
   **   ~~~   **   Minimum should be >=0.000 and Maximum should be <=1.000

The following are relevant lines from the in.idf file:

  Fractional,                             !- Name
  0,                                      !- Lower Limit Value {BasedOnField A3}
  1,                                      !- Upper Limit Value {BasedOnField A3}
  Continuous;                             !- Numeric Type

  2LLO Tuesday,                           !- Name
  Fractional,                             !- Schedule Type Limits Name
  Linear,                                 !- Interpolate to Timestep
  06:00,                                  !- Time 1 {hh:mm}
  0,                                      !- Value Until Time 1
  07:15,                                  !- Time 2 {hh:mm}
  1,                                      !- Value Until Time 2
  16:15,                                  !- Time 3 {hh:mm}
  0,                                      !- Value Until Time 3
  18:15,                                  !- Time 4 {hh:mm}
  1,                                      !- Value Until Time 4
  24:00,                                  !- Time 5 {hh:mm}
  0;                                      !- Value Until Time 5

The errors are eliminated when Linear is replaced with Average in interpolate to Timestep. Am I doing something wrong?

Here is a link to the idf file.

It is possible that you have come across a bug related to the new linear interpolation code. Could you send me the IDF file to me to test. jglazer at gard dot com

@JasonGlazer I just added a link to the IDF file. let me know if you can access it. By the way when I cleared that issue I get problem with Foundation for walls having air gap.

You discovered a bug in the EnergyPlus 8.9.0 code related to the new linear interpolation method. I posted the issue here. As a work around, instead of using 0 and 1 in the schedule, try using 0.001 and 0.999.
