Zio®/Zio Plus LCD Wall Modules
TR70, TR71, TR75 WITH Sylk® Bus
SPECIFICATION DATA
GENERAL
The TR70 Series Zio (TR70/TR70-H, TR71/TR71-H) and Zio Plus (TR75/TR75-H) are 2-wire, non-polarity sensitive, Sylk bus communicating wall modules for use with Spyder® and ComfortPoint™ 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 TR7-H, TR71-H and TR75-H models include an onboard humidity sensor.
NOTE: Refer to the Zio/Zio Plus LCD Wall Modules Operating 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 application.
FEATURES
The TR70 Series wall modules include:
•Ability to control tenant access to controller parameters via password protection.
•Ability to assign labels for enumerated values.
•Customized parameter access, by using the Honeywell WEBs-AX Workbench tool.
•Ability to link setpoint limits to a network variable.
•Programmable for: Home screen options, tenant access, contractor access, optional password protection to contractor mode, access to controller parameters, setpoint, override, fan, and other parameters.
•Ability to access and adjust most parameters in the programmable controller.
•TR75 can access and adjust the controller schedule.
•Ability to balance the VAV system from the wall module.
•Home screen 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.
•Network bus jack.
•Simple 2-wire terminal connection to the programmable controller (includes power) and an optional 2-wire terminal connection for the network. All connections are polarity insensitive.
•Permanent retention of user configuration, including setpoints after a power outage.

ZIO®/ZIO PLUS LCD WALL MODULES
SPECIFICATIONS
Compatibility: Full feature set, including scheduling and password protection requires the latest Spyder firmware (field upgradeable with Spyder Flash Tool), Spyder Tool version greater than 5.18, and WEBs-AX Workbench version 3.4.57 or greater.
Construction: Two-piece construction, cover and internally wired subbase. Field wiring, 18 to 24 AWG (0.82 to 0.20 sq. mm), connects to a terminal block in the subbase.
Mounting Options: The LCD wall modules can be mounted on a standard two by four inch junction box or on a 60 mm diameter junction box. The modules may be mounted up to 200 ft. (61 m) from the programmable controller. Twisted pair wiring is recommended for distances longer than 100 ft. (30.5 m).
Dimensions (H/W/D): See Fig. 2 on page 2.
Environmental Ratings:
Operating Temperature: 30°F to 110°F (-1°C to 43°C) Shipping Temperature: -40°F to 150°F (-40°C to 65.5°C) Relative Humidity: 5% to 95% non-condensing
Temperature Setpoint Range: Default range is 55°F to 85°F (10°C to 35°C); configurable for other ranges.
Temperature Sensor Accuracy: ±0.36°F at 77°F (±0.2°C at 25°C)
Humidity Sensor Accuracy (TR71-H/TR75-H only): ±5% RH from 20% to 80% RH
Power: 18 Vdc power is supplied to the wall module from the 2-wire S-BUS connection to the programmable controller.
Accessories: 50007298-001 (pack of 12) medium, cover plate; 6-7/8 x 5 in. (175 x 127 mm).
Approvals: CE; UL94-HB plastic enclosure; FCC Part 15, Class B

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- 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
