I am trying to take an existing hospital building file (idf) from Atlanta, Georgia, and simulating it with a weather file (IWEC) from Johannesburg, SA. Based on my research, Johannesburg and Atlanta should have similar climates. I didn't make any additional changes in the idf file except changing the latitude, longitude, time zone, and elevation to match Johannesburg numbers. I am encountering this severe error in which the chiller is failing. Has anybody dealt with this before? Please help

** Severe  ** FindRootSimpleController: Controller error for controller = "CAV_2_COOLC_CONTROLLER"
**   ~~~   **  Environment=RUNPERIOD 1, at Simulation time=08/26 01:45 - 02:00
**   ~~~   **   Controller function is inconsistent with user specified controller action = Reverse action
**   ~~~   **   Actuator will be set to maximum action
**   ~~~   ** Controller control type=Temperature and humidity ratio
**   ~~~   ** Controller temperature setpoint = 7.76E-003 [C]
**   ~~~   ** Controller sensed temperature = 7.81E-003 [C]
**   ~~~   ** Controller humidity ratio setpoint = 7.76E-003 [kgWater/kgDryAir]
**   ~~~   ** Controller sensed humidity ratio = 7.81E-003 [kgWater/kgDryAir]
**   ~~~   ** Controller actuator mass flow rate set to 12.37 [kg/s]
