TABLE 1—CNAP NETWORK VARIABLES.
NOTE: THE FOLLOWING INPUTS/OUTPUTS ARE COMMONLY USED WITH THE NETWORK VIA DATA-
SHARING.
Variable Name Description Point Information
Discharge Air Temperature Used for datasharing to zone controllers Physical analog input on VAV
(Control Number 1) to indicate supply air temperature controller data shared to zone
available for zone heating or cooling. controllers.
Outdoor Air Temperature Outdoor air temperature datashared Physical analog input on source
(Control Number 5) among controllers from one source controller datashared to remote
point. analog inputs on destination
controllers.
Zone Occupied Status Summary of all VAV terminal box User assigns to remote analog
(Control Number 80) control (W7620) occupied status input on the W7600. The Zone Occu-
information used to force the VAV pied Status must be datashared from the
control into occupied mode when W7620 VAV Box controllers to the
a zone has demand: W7600 (many to one logical OR operat-
1 = unoccupied ion).
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.).
RestoreShed flag Bump discharge air cooling Remote digital input.
(Control Number 165) setpoint upward to shed cooling load.
Network Occupied Flag Used to force the VAV control Remote digital input.
(Control Number 166) to the occupied mode via
network communication.
Network Controlled Digital Used for TOD control of lighting, Destination point for ON/OFF
Outputs exhaust fans, etc. control via network. A remote digital
(Control Numbers 248-255) 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.
