Command Syntax
Siemens Building Technologies, Inc. 3-47
ENCOV (Enable COV)
Unitary pre-APOGEE APOGEE BACnet
Syntax
ENCOV(pt1,...,pt16)
pt1
through
pt16
Point name that is enabled to report updated changes-of-
value (COV).
Use
Enables devices to report change-of-value (COV) information to
other nodes. When this command is executed, all operations that
use COVs to function will start reporting.
Unless the points defined in this command are disabled, updates to
graphics, archiving, COV printing, alarming, and in some cases
evaluation of equations are reported.
• Points defined in the statement must reside in the same device
as the command.
• A maximum of 16 points can be controlled with one ENCOV
command.
Example
50 IF (SFAN.EQ.ON) THEN ENCOV(ROOM1, ROOM2)
ELSE DISCOV(ROOM1,ROOM2)

EPHONE (Enable phone)
Unitary pre-APOGEE APOGEE BACnet
2.1 only
Syntax
EPHONE(pn#1,...,pn#16)
pn#1
through
pn#16
Telephone ID numbers that are defined in the device.
Use
Enables telephone ID numbers. The telephone ID number is a
numeric code that represents the actual telephone number defined in
the device.
A maximum of 16 telephone number IDs can be enabled with one
EPHONE command.
Example
530 EPHONE(1,2,3,5,6)
Notes
Do not use the EPHONE command over the network.
