[Equest-users] Zero Relative Humidity

I am modeling a supermarket with a warehouse in back. The warehouse is equipped with  unit heaters to warm indoor air to 55 deg. F (Max) and exhaust fan capacity of 22,000 cfm. I modeled infiltration as 9 cfm/sq.ft. per rollup door and set the exhaust fans to purge twice a day for 2 hours total. The 55 deg. F setpoint is scheduled, and the facility is in the deep south (Florida).

I am consistently getting humidity values of zero in the hourly report (RH, *, Twet-bulb, doesn't matter). Anyone ever had similar experience?
