Perhaps I misunderstand but never heard of AC adjusting fan speed on its own.
Ours is as follows.
High constant
Low constant
Auto high
Auto low.
Depends on the system. Dometic, on AUTO, the AC compressor is ON and if more than 5 degrees diff, the HI fan will come on. Once the AC gets closer or less than that 5 degree, the Fan will "shut" of for a second and then restart on LOW and once temp is reached will shut both Compressor OFF and the Fan OFF. From your desciption, you have a RVP(Coleman) wall tstat. And yours operates as you state. This is for the LCD Coleman tstat. Doug
Set Fan Speed for Cooling Mode
1. Place the slide switch in the COOL position.
2. Pressing the MODE button will toggle through the available speeds.
• “COOL AUTO” setting allows the speed to vary depending on the cooling needs which
is the default setting.
• “COOL HIGH” or “COOL LOW” setting will set the fan speed to run continuously at high
or low, but the upper unit will cycle when cooling is needed.
• “FAN HIGH” and “FAN LOW” setting will set the fan to run continuously at high or low
speed. The upper unit will not run to produce cooling. Setpoint is not adjustable in this
mode.
