Why do they have the High/Low option? I know it moves a higher volume of air, however, on The lower speed it would seem to heat or cool the air better on the lower speed.

I finally did it - I replaced the analog thermostat with digital thermostat

It appears to be a wire-for-wire replacement. Same number, same color wire assignments, only the newer thermostat is digital.

The hysteresis on the analog thermostat (NEW) was almost 10 degrees from time it cut on to time it cut off, very sloppy - about 5 degrees plus/minus of the setting. I'm hoping the digital version of the thermostat is much less.

It took all of about 5 minutes to complete, and have finished. The new thermostat was a wire-for-wire replacement (6 wires, 6 wirenuts to twist off then on the new thermostat).

The hysteresis is far better than the old. I set the new thermostat to 72 degrees and opened the windows to cool the trailer. When it hit 71, the heater came on, and went off at 73 degrees. That is much better than the +/- 5 degree spread of the analog thermostat. And the added benefit, I have a digital temperature display to tell me what the actual temperature is.

With the $20 Hunter stat from Walmart, you can change the hysteresis by holding down both the up and down buttons at the same time for about 4 seconds. I believe you can change it from 1 to 4. I put two in my MH and even wired it so I can control the furnace from the bedroom stat.
