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 ver-

sion 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

Fig. 1 illustrates the location of the terminal block and other 

features on the TR70 Series wall modules.

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
