How can I avoid coldstart in EnergyPlus simulation when the RunPeriod starts on Saturday when the HVAC system is unavailable? I currently defined the RunPeriod object as follows:

RunPeriod,
Annual,                  !- Name
1,                       !- Begin Month
1,                       !- Begin Day of Month
2022,                    !- Begin Year
12,                      !- End Month
31,                      !- End Day of Month
2022,                    !- End Year
Saturday,                !- Day of Week for Start Day
No,                      !- Use Weather File Holidays and Special Days
No,                      !- Use Weather File Daylight Saving Period
Yes,                     !- Apply Weekend Holiday Rule
Yes,                     !- Use Weather File Rain Indicators
Yes,                     !- Use Weather File Snow Indicators
No;                      !- Treat Weather as Actual

I tried increasing the minimum number of warming-up days to 30 but it didn't help. The simulation results still show unrealistic zone air temperature values (around 10*C) in the first few days as if the entire warming-up period had 30 Saturdays.

Are there any best practices for handling simulations that start on weekends to avoid cold start issues? Any insights or suggestions would be greatly appreciated. Thank you!
