Network Variables—A class of variables defined in Neuron C 

that allows communication over the L

ON

W

ORKS®

 network to 

other nodes on the network. An output network variable in one 

node can be bound to a corresponding input network 

variable(s) in other node(s). Changing the value of the output 

network variable in one node causes the new value to be 

automatically communicated to the bound input network 

variable(s) in other node(s). When an input network variable is 

updated, a nv_update_occurs and the event is posted at the 

receiving node(s) so that the application program can take 

action based on the change. A network management node 

(for example XL15A or XL15C) that explicitly reads and/or 

writes the network variable can also poll network variables. 

Network variables can contain one data field (one or two 

bytes) or multiple data fields (a structure).

Neuron—Refers to the Echelon

 semiconductor device which 

implements the L

W

ORKS®

 protocol on a network connected 

device such as the T7350H Honeywell controller.

Node—A device implementing layers one through six of the 

LonTalk

®

 protocol including a Neuron

®

 Chip, transceiver, 

memory, and support hardware.

Notebook PC—Portable personal computer.

PDA—Personal Digital Assistant. In the case of the T7350 

product this is a hand held electronic device operating with the 

Palm OS. A Honeywell provided PDA application program is 

used to configure the T7350 thermostat using a direct RS232 

connection. Before purchasing a PDA, check the latest 

Configuration software release note for a list of qualified PDA 

models. Network connected T7350H models can be 

configured without a PDA using L

Programmable Controller—A controller that has a variable 

number of control loops of different types and is user 

programmed to execute an application. The user can select 

the number and type of control loops. The user also has the 

capability of generating new types of control loops. Some 

examples of Honeywell programmable controllers include the 

XL15A and XL15B.

Recovery Mode or Recovery Period—The time in 

unoccupied periods when the temperature control is adjusting 

the control setpoint so that the space temperature reaches the 

occupied setpoint when the schedule change occurs.

RIO—Excel 10 Remote Input/Output device.

RTC—Real Time Clock.

Schedule—The structure that defines the occupancy states 

and the time of the changes between these states. In the case 

of the T7350, schedules are organized around a eight day 

weekly structure including an extra day for designated 

holidays. Holidays are scheduled by yearly calendar events.

SGPU—Significant Event Notification and Guaranteed 

Periodic Update.

SGPUC—Significant Event Notification and Guaranteed 

Periodic Update with Change Field.

SLTA—Serial LonTalk

®

 Adapter. Adapts the transformer 

coupled LonTalk

®

 messages to the RS-232 Serial Port.

SNVT—Standard Network Variable Type.

SCPT—Standard Configuration Parameter Type.

XL15A—W7760A Honeywell building level controller.

XL15B—W7760B Honeywell building level controller.

XL15C—W7760C Honeywell plant level controller.

Models: See Table 4.

Dimensions: See Fig. 2.

Finish (color): Trident White.

Batteries: No batteries required.

a

All models are down-selectable and can be configured to control fewer stages than the maximum allowed.

b

Heat pump applications for these models have a maximum of two heat stages and two cool stages.

c

One extra stage (of either heat or cool) can be configured using the auxiliary relay.
