I have been tuning my CIS and I noticed the control pressure was out of spec, so I decided to take the WUR apart. I cleaned it very well (I pulled out the disk and everything) and noticed that there is an adjustment that shuts off power to the heater on the bi-metalic strip. I did not adjust at this time and put back together. My control pressure started low in spec for the current temp and then went high. I then turned the adjusting screw that shuts off power to the heating element and was able to adjust my warm CP in spec.

The reason I am posting this is beacuse I have a read a lot about making an adjustable WUR with no mention to the current adjustment in the unit.

Has anyone else have experience with this?
