Zio™LCD Wall Modules
TR70 AND TR70-H with Sylk™bus
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.
• Programmable for: Home screen options, tenant
access, contractor access, access to controller
parameters, setpoint, override, fan, and other
parameters.
• Eight pre-programmed configurations (e.g. VAV with
balancing) in the wall module configuration tool.
• Ability to access and adjust most parameters in the
programmable controller (except Scheduling).
• 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 and an optional 2-wire
terminal connection for the network. All connections
are polarity insensitive.
• Retention of user configuration, including setpoints
after a power outage.
SPECIFICATIONS
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.
