Requirement: Form NRCA‐PRC‐03‐F step A 4 instructs "Temporarily
place the system in unoccupied mode and override the programmed
unoccupied sensor alarm differential from 30% for 4 hours to 1% for 5
minutes."
Solution: Note that the controller measures deviation in ppm, not
percent. Change the event screen to outlier deviation 0 ppm duration
5 minutes.
Note that Honeywell Analytics E3Point CO sensors have a resolution
of 1 ppm.
Requirement: Form NRCA‐PRC‐03‐F step A 5 instructs "Temporarily
override the programmed occupied sensor proximity zone alarm dif‐
ferential from 30% for 4 hours to 1% for 5 minutes."
Solution: Like step A 4, Set the event screen to deviation 0 ppm and
duration 5 minutes.
