[Strt] sets the system to ramp only at startup.
[StPt] sets the system to ramp at startup and whenever the set point
changes.
[``rP] This prompt appears only on controllers with [`rSP] (Input Menu)
set to [`OFF] and with [`Ei1] not set to [`rSP] and with [CntL] (Global
Menu) not set to [diff] or [rati].
