The automatic temperature selections are useless indeed, at least for me.
I have used a similar machine for years that I rescued in 1993, and never used the automatic feature, it may as well not be there. I do like that the switch includes manual selections with warm rinses.
This was the most popular model in the 1983-1986 line-up, and was the first model with the Auto+5 temps. All machines in that line either had 3-temps all with cold rinses or the Auto+5, nothing in between. The last machine to have just plain 5 was a popular 1981 model.
The one thing that I would change with these machines - the three water levels. Almost invariably, I want the level in between medium and ex. high. The next model up from this had 5-levels.
