Note: 1. A deviation is defined as deviation from SP.
2. An absolute alarm is defined as a fixed value X with reference to 0.
3. Standby sequence is defined as having the alarm outputs inactive until SP is reached on the initial power up of the Controller.
After SP has been reached, alarms will function normally.
