TABLE 1—CNAP NETWORK VARIABLES.
Description
Used for datasharing to zone controllers
to indicate supply air temperature
available for zone heating or cooling.
Outdoor air temperature datashared
among controllers from one source
point.
Summary of all VAV terminal box
control (W7620) occupied status
information used to force the VAV
control into occupied mode when
a zone has demand:
1 = unoccupied
2 = occupied
4 = unoccupied override
8 = warmup
16 = continuous unoccupied
NOTE: Numbers other than those
listed indicate mixed variations
of VAV box status (occupied
unoccupied, warmup, etc.).
Bump discharge air cooling
setpoint upward to shed cooling load.
Used to force the VAV control
to the occupied mode via
network communication.
Used for TOD control of lighting,
exhaust fans, etc.
Indicates current mode of operation
of the W7600 VAV control.
Indicates OCC/UNOCC status of the
VAV air handling unit and is a
digital point type for use as a
network datashare source point.
Indicates when the W7600 VAV
control determines that morning
warmup is engaged.
Indicates the economizer enable
function so only one outdoor
enthalpy sensor needs to be used on the
network. Used as a source point for
datasharing to other controllers.
Indicates OCC/UNOCC status of the
time of day schedule only in the VAV
AHU controller. Used as a network
datashare source point.
Indicates current discharge air cooling
setpoint including reset.

Point Information
Physical analog input on VAV
controller data shared to zone
controllers.
Physical analog input on source
controller datashared to remote
analog inputs on destination
controllers.
User assigns to remote analog
input on the W7600. The Zone Occu-
pied Status must be datashared from the
W7620 VAV Box controllers to the
W7600 (many to one logical OR operat-
ion).
Remote digital input.
Remote digital input.
Destination point for ON/OFF
control via network. A remote digital
input for the Network Controlled
Digital Output is automatically config-
ured by the software when a remote dig-
ital output is configured by the user.
Heat or Cool indicated.
OCCUP or UNOCC indicated.
WARM or No WARM indicated.
ECON or No ECON indicated.
OCCUP or UNOCC indicated.
Numerical value indicated.
