Command Syntax
Siemens Building Technologies, Inc. 3-73
OFF (Off status)
Unitary pre-APOGEE APOGEE BACnet
Syntax
OFF(pt1,...,pt16)
pt1 through
pt16
Point names that are commanded to OFF.
OFF(@prior,pt1,...,pt15)
@prior
Defines a specific point priority.
pt1 through
pt15
Point names of LDI, LDO, L2SL, L2SP, LOOAL, LOOAP,
LFSSL, or LFSSP points.
NOTE: The OFF(@prior) command is not available in Unitary
firmware.
Use
Changes the operational status of an ON/OFF/AUTO point to OFF.
• Acceptable point types are: LDI, LDO, L2SL, L2SP, LOOAL,
LOOAP, LFSSL, and LFSSP.
• A maximum of 16 points can be changed with one OFF
command.
• A maximum of 15 points can be defined with one OFF(@prior…)
command.
Example
20 IF (OATEMP.GE.63.0) THEN OFF(@NONE,PUMP1,PUMP2)
Notes
FAST/SLOW/STOP points (LFSSL, LFSSP) use the OFF command
for STOP.
