Abstract
An adjustment control for a thermostatic valve consists of a non-rotatable component to the valve on which is mounted a rotatable knob for setting the temperature control, the knob having a maximum rotation of about one revolution. A releasable auxiliary device is provided which is operable between the component and the knob at a predetermined intermediate rotational position of the knob to limit the rotation of the latter.
