Thank you for your question. The rotational limit stop can be adjusted for the Delta Monitor T17430-SS shower trim. To adjust the adjust the rotational limit stop, first remove the temperature cover and take a Phillip's head screw driver and turn the set screw counter clockwise to remove.
Next, remove the gray knob. Behind the knob, you should see a black disk. Please take this disk and take it out and place the disk to the hotter side. The hot side should be up against the iron piece that is sticking down on the volume handle.
