The Pearl Controller allows you to have up to 6 cooling and 6 heating stages.
To get to location to setup your temp staging you would do the following:

On this screen you will select the maximum number of cooling and heating stages that you intend to use.
The up and down arrow keys are used to increase or decrease the amount of stages for cooling and heating.
If, for example, you select 2 heating stages, then in the remainder of the programming only 2 heating stages will be displayed The third selection is the Stage Width . This is the number of degrees between each of your stages, sometimes referred to as “Stage Separation”. Typically, users select either 1 or 2 degrees.
Using the NUMERICAL VALUE TABLE
if you highlight a numerical value you can always change it by hitting the Enter Button on controller, this will pop up a numerical table and you would navigate hitting up/down/left/right buttons, the back arrow is to delete values, x cancels the settings, and the check mark saves your changes.
