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.  
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.  
Permanent retention of user configuration, including  
setpoints after a power outage.  
Table 1. TR70 Series Features.  
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.

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

and S-BUS is 18-24 AWG (0.82 to 0.20 sq mm) depending on  
application, 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.

cation.  
Sample Tenant LCD Displays  
The Fan and Occupied settings are optional for Home screen  
setup. If there are no parameters configured for Tenant  
access, the “View More” softkey does not display on the  
Tenant Home screen.

softkeys. Contractor mode also allows for customizing the  
Tenant view, including setting the tenant’s Home screen and  
“View More” access.
