Use the restricted adjustment mode to limit the temperature range over which end users can adjust the control and avoid over-adjustment of your heating or cooling application.

The adjustment range is limited by setting the high and low temperature stop values. See Figure 1.

You can also set the restricted adjustment range equal to the On and Off temperatures to eliminate any temperature adjustment on the control by end users, effectively locking the control adjustment features.
