Controller sets bypass timer to 1
20 minutes (default configured occupied bypass
time). The bypass timer starts to count down to zero. Concurrently, the controller
may change its current mode to unoccupied or occupied standby (possibly due to
a change based on the system time of day schedule). If it does, the controller
switches to occupied bypass mode for the remainder of the bypass time or until the
zone sensor CANCEL button is pressed. If the bypass timer counts down to zero, the
timed override is disabled.
