GENERAL

The TR70 and TR70-H are 2-wire, non-polarity sensitive, Sylk bus communicating wall modules for use with Spyder™ (PUL6438S, PVL6436AS, and PVL6438NS models only) and ComfortPoint™ (CP-UL6438S, CP-VL6436AS, and CP-VL6438NS models only) programmable controllers.

All models have a space-temperature sensor, network bus jack, and an LCD panel with three softkeys and two Up/Down adjustment keys. The TR70-H model includes an onboard humidity sensor.

NOTE: 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 application.

FEATURES

The TR70 and TR70-H wall modules include:

• Ability to control user access to controller parameters.

• Customized parameter access, by using the Tridium Niagara Workbench tool.

• Retention of user configuration, including setpoints

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 nonplenum 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.
