Communications
The wall modules use a sensor bus (S-BUS) for
communications with the programmable controller.
For network communication, the building’s LON network wires
connect to the two terminals (NET-1 and NET-2). 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 Level IV, 22 AWG (0.33 sq. mm) 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:
1.
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.
2.
Refer to the Zio™ LCD Wall Modules TR70 and
TR70-H with Sylk™ bus – Operating Guide (form
63-2667) for information about customizing the
wall module configuration, such as modifying the
default Home screens or creating your own appli-
cation.
