AUTO FAN (Cooling Demand)
Control Panel Operation Instructions
During the (SYSTEM mode COOL or HEAT), the fan speed automatically varies depending on the difference between the unit's set point on the control
panel and the actual room temperature. Let me explain. Say for example, you’re working in your garage and you open the big door for several minutes. The
system will sense a wide difference between the set point and the actual room temperature. When this occurs, the system
fan speed increases to HIGH for
a period of time. The fan speed decreases, in step, as the temperature difference decreases. When the room temperature matches the system's set point,
fan speed returns to the lowest setting, and if the fan mode is on AUTO FAN, the fan will stop.
