Thank you for your question. The T4774-FL does have a rotational limit stop that can be adjusted to regulate temperature. To get to the rotational limit stop, remove the handle with a 1/8" allen wrench. You will then see the white, round limit stop around the stem of the cartridge. To adjust the temperature pull the white Rotational Limit Stop outward and rotate. Clockwise rotation will decrease the outlet temperature, counterclockwise rotation will increase the outlet temperature. Temperature change per tooth (notch) could be 4° - 16°F based on inlet water conditions. Repeat as necessary. When finished, make sure that the Rotational Limit Stop is fully retracted into the seated position.
