Q&A for Hard-Wire Fan and Pre-Wired Fan Thermostat:
Question:  So I hooked everything up according to instructions from power supply to thermostat to fan.  It works, but it seems to be reversed.  When I set the temp to higher, the fan turns off, and when I lower it to below the air temp, it turns on.
Answer:  The wiring is correct. This is the correct operation for a cooling fan. The fan should only turn off when the ambient (room) temperature is below the thermostat set point. If you want 85 degrees maximum, set the thermostat for 85 degrees.  The fan will turn On at any temperature above 85, and turn off when the room temperature drops below 85 degrees.
