normal operating modes, such as CTL_COOL. When the effective
occupancy changes to unoccupied or 24 hours have elapsed since
the last start-up or CTL_FLOATING_OUT_SYNCH mode, the
controller enters this mode again to reset the floating output
position tracking.
CTL_START_UP_WAIT is the first mode after an application
restart. No control algorithms are active, and heat/cool outputs stay
in their default positions. CTL_FLOATING_OUT_SYNCH follows.
CTL_DISABLED disables heat/cool control.
