Process alarm = Process high alarm, Process low alarm, Process high alarm (with hold action),
Process high alarm (with hold action)
SV alarm = SV high alarm, SV low alarm
Deviation alarm = Deviation high alarm, Deviation low alarm, Deviation high/low alarm, Band
alarm, Deviation high alarm (with hold action), Deviation low alarm (with hold
action), Deviation high/low alarm (with hold action)

When there is not alarm 3, attribute becomes RO (read only).
When the alarm 3 is FAIL alarm, attributes become RO (read only).
3
For heat/cool control: Heat-side proportional band
4
In case of heat control, become RO (read only).
5
Minus (-) setting results in overlap.
