Hi Everyone

I am going to model a simple zone with 2 spaces (one inside wall) in OpenStudio. I am going to find the inside wall surface temperature after a jump in temperature from 0 to 20 DegC. ( for a validation with a heat transfer problem). To do so, I model the temperature step change in thermostat set-point profile. ( from 0Am to 8AM = 0 Degc and after that 20 DegC). But when I look at the results, the minimum zone air temperature is around 12 Degc. why it does not come to zero? ( I do not know its related or not, but what is temperature type limit name? for example temperature 38)
