Honeywell TR70, TR71, TR75, Zio®/Zio Plus LCD Wall Modules Manual

The Zio TR70 Series (TR70, TR70-H, TR71, TR71-H, TR75, and TR75-H OS numbers) LCD Wall Modules provide an operator interface for monitoring and adjusting parameters in the wall module itself and in the programmable controller (refer to the Honeywell Spyder® User’s Guide, form 63-2662, or the ComfortPoint™ Programmable Controller User’s Guide, form 63-2663, depending on the programmable controller used) to which it is wired. The wall module may be customized and supports both a contractor and a tenant user interface.

NOTE: This document illustrates the wall module configuration process using information from the Honeywell Spyder User’s Guide (form 63-2662).

The wall module has a snap in mounting to a subbase that may be mounted on a wall, on a standard utility conduit box, or on a 60 mm wall outlet box. Wiring connections to the wall module are made through a cutout in the back of the wall module. All models have a space temperature sensor, network bus jack, and an LCD panel with three softkeys and two Up/Down adjustment keys. Models with -H also include an onboard humidity sensor.

This Operating Guide is intended to provide configuration information (using the Niagara Workbench tool) and a general overview of the TR70 Series operator interface. Configuration begins with “Initial Power-Up” on page 2, and the general overview begins with “Operating the Zio Wall Module” on page 19. It is intended to guide you through the features and operation of the TR70 Series as you interface with the programmable controller and establish pre-programmed or custom configurations.

Honeywell TR70, TR71, TR75 Compatibility

The TR70 Series LCD Wall Modules operate with the Sylk Enhanced Spyder Controller or the Sylk Enhanced ComfortPoint Controller. The table below provides compatibility information for each model. The TR71/TR75 can replace a TR70 in an installation where an upgrade to WEBs- AX or Spyder or reprogramming is not desired. Features like scheduling, additional memory, etc. will not be available.

Likewise, a TR71 can be replaced by another TR71 or TR75 without reprogramming required. A TR75 can only be replaced with a TR75 where no reprogramming is desired.

Honeywell TR70, TR71, TR75 INITIAL POWER-UP


  1. Make sure the TR70 Series wall module is properly mounted and properly wired and connected to the programmable controller.
  2. Refer to the Zio™ LCD Wall Modules TR70 Series with Sylk™ Bus – Installation Instructions, form 62- 0271, for specific installation requirements.

Upon initial power-up before configuring the wall module, the LCD screen displays the phrase “PLEASE LOAd” in the Label/ Value area of Fig. 2. This phrase alternates with any onboard sensor display such as temperature. The TR71/TR75 also display the firmware revision number, model number and Sylk bus address as shown in Fig. 27. Fig. 2 illustrates all the possible LCD Wall Module display elements. Only those elements pertinent to the current configuration and status actually display.


Initial Setup and Configuration

Once the wall module is wired to the controller, you configure the wall module using the PC-based, Niagara Workbench Tool. Refer to the applicable programmable controller User’s Guide. (Refer to the Honeywell Spyder User’s Guide, form 63- 2662, or the ComfortPoint Programmable Controller User’s Guide, form 63-2663, depending on the programmable controller used.) This tool is used to configure the wall module for either the Spyder or the ComfortPoint programmable controller.

Confirm Bus Address Setting

Check to ensure that the Wall Module’s bus address dial (located on the back of the module) is set to match the setting in the configuration tool. TR70 models can be set from 1–5 and TR71/TR75 can be set from 1–10 (0 on the Zio address dial is equal to 10 in the configuration tool). The address must be different for each device on the Sylk bus. Up to four Zios per Spyder are allowed with any combination of TR71/TR75s and up to three Zios are allowed if one or more is a TR70 model.

Selecting the Wall Module

You will use the Sylk S-Bus wall module function block from the Palette’s Built-In folder (see Fig. 3). This configuration has nothing programmed except the room temperature parameter and occupancy status.

  1. Add the Sylk S-Bus Wall Module function block to the wire sheet via a left click, drag, and drop. See callout 1 in Fig. 3.
  2. Right click on the S-Bus Wall Module function block to open the Configuration Properties menu. See callout 2 in Fig. 3.
  3. Left click on the title, Configuration Properties. This action starts the Configuration Wizard. The Configuration Wizard steps (see Fig. 5 on page 4) are used to configure the wall module.

TR71/TR75 Labels

The TR71/TR75 allows the use of the following special characters in label fields such as Categories and Parameter Names: underscore ( _ ) to insert a space, hyphen ( - ), and forward slash ( / ). The TR70 allows use of the underscore ( _ ) character to insert a space.

Navigation and Memory Usage

The Honeywell Spyder Tool uses an intuitive, window-based interface. A Help button on each screen provides assistance with any entry or process.

Use the Help button to display context specific help for the current window or pane display. See the lower left corner of Fig. 6 on page 5 for the location of the Help button.
NOTE: At any time, clicking the Preview button (lower left of main window, see Fig. 6 on page 5) displays the updated wall module LCD as a pop-up. Preview simulates the actual wall module interface and allows you to verify the operation of the current configuration of the wall module. See “Preview” on page 16.

Table 3 describes the navigation buttons at the bottom of the wall module window. See the bottom of Fig. 7 on page 5 for the location of these buttons. Buttons are greyed when unavailable.
