Floating indoor temperature shift - incorrect IP/SI conversion?

Post by zekk828 » Mon Oct 12, 2020 2:47 pm -1100

Forgive me for using IP units, but I think I may have found a conversion error with regard to the "floating indoor temperature shift" input under ASHRAE 160 user-defined climate. Assuming this is meant to represent the dead-band temperature range, I would want to list 2.5 degrees C, or 5 degrees F. However, when I enter 5F, there's essentially zero variation in temperature. When I enter 36.5F, however, it translates to 2.5C when I switch to SI units. So I think that instead of converting from relative F-->C, it's converting literally from degrees F to degrees C. In other words, I think WUFI is translating 5F to -15C, rather than 2.5C. Is this a bug, or do I not understand what "floating indoor temperature shift" is?
