Communications

The wall modules use a sensor bus (S-BUS) for

communications with the programmable controller.

For network communication, the building’s LON or BACnet®

network wires connect to the two terminals (NET-1 and NET-

). See Fig. 1. A network bus port is accessible at the bottom

of the wall module by removing the jack plug.

The network bus and S-BUS terminals (see Fig. 1) are

insensitive to polarity, minimizing installation errors due to

mis-wiring. The recommended wire size for the network bus

and S-BUS is 18-24 AWG (0.82 to 0.20 sq mm) depending on

application, plenum or non-plenum rated, unshielded, twisted

pair, solid conductor wire.

LCD Display

The LCD display may be customized for tenant and contractor

users. The following are a few samples of the various Home

screens that are configurable for the LCD Wall Modules. Not

all possible Home screens are illustrated here. There are

many other configurable Home screens.

NOTES:

Home screens can display one to three of any of

the following parameters: Temperature Setpoint,

Room Temperature, Room Humidity, Outdoor

Humidity, Outdoor Temperature, and Time, or one

of virtually any parameter in the controller.

ating Guide (form 63-2719) for information about

customizing the wall module configuration in the

WEBs-AX Workbench, such as modifying the

default Home screens or creating your own appli-

cation.

Sample Tenant LCD Displays

The Fan and Occupied settings are optional for Home screen

setup. If there are no parameters configured for Tenant

access, the “View More” softkey does not display on the

Tenant Home screen.

Sample Contractor LCD Displays

The Contactor mode allows advanced options using the

softkeys. Contractor mode also allows for customizing the

Tenant view, including setting the tenant’s Home screen and

“View More” access.
