recovery is turned on. The controller remembers its state
(on or off) prior to a power interruption and returns to that
state (at the beginning of the prior ISO operating cycle)
when power is restored. If power is interrupted while the
controller is in the Manual cycle mode, the controller will
return to the prior ISO operating cycle and not the Manual
cycle when power is restored.
