INSTALLATION INSTRUCTIONS
BEFORE INSTALLATION
Fig. 1. LCD Wall Module.
Erratic System Operation Hazard.
Failure to follow proper wiring practices can
introduce disruptive electrical interference (noise).
Keep wiring at least one foot away from large inductive
loads such as motors line starters, lighting ballasts,
and large power distribution panels.
Shielded cable is required in installations where these
guidelines cannot be met.
Ground the shield only to the grounded controller
case.
IMPORTANT
All wiring must comply with local electrical codes and
ordinances or as specified on installation wiring diagrams.
— For information on Sylk bus distance limitations, see
Table 1 on page 2.
— All wiring is polarity insensitive.
INSTALLATION
Mount the wall module on an inside wall approximately 54 in.
(1372 mm) from the floor (or in the specified location), to allow
exposure to the average zone temperature. Do not mount the
wall module on an outside wall, on a wall containing water
pipes, or near air ducts. Avoid locations that are exposed to
discharge air from registers or radiation from appliances,
lights, or the sun.
The wall module can be mounted on a wall, on a standard
utility conduit box using No. 6 (3.5 mm) screws or on a 60 mm
wall outlet box (see Fig. 3). When mounting directly on a wall,
use the type of screws appropriate for the wall material.

Wiring
All terminal connections can be made to the backside of the
module. There are no field adjustable/replaceable
components inside the module.
Attach the wires from the programmable controller and
network to the appropriate wall module terminals, as indicated
in Fig. 6 on page 3.
Improper Electrical Contact Hazard.
Screw-type terminal blocks are designed to accept
no more than one 14AWG (2.5mm sq) conductor.
Connect multiple wires that are 14AWG (2.5mm sq)
with a wire nut. Include a pigtail with this wire group
and attach the pigtail to the individual terminal block.
Wiring Wall Modules
Wire the terminal block shown in Fig. 6 as follows:
1. For single wires, strip 3/16 in. (5 mm); for multiple wires
going into one terminal, strip 1/2 in. (13 mm) insulation
from the conductor. See Fig. 5 for wiring multiple
TR40/42s.
2. Insert the wire in the required terminal location and
tighten the screw to complete the termination.
3. Review and verify the terminal connection wiring
illustrated in Fig. 6.

As a rule of thumb, single twisted pair (2 wires per cable
only), thicker gauge, non-shielded cable yields best results
for longer runs.
c
The 30 m distance for standard thermostat wire is conserva-
tive, but meant to reduce the impact of any sources of electrical noise (including but not limited to VFDs, electronic
ballasts, etc). Shielded cable recommended only if there is a
need to reduce the effect of electrical noise.
d
These distances also apply for shielded twisted pair.

Attaching the Wall Module to the Subbase
When all wiring is complete, hook the top side, and then snap
down like on a hinge. See Fig. 8.
Removing the Wall Module from Subbase
To remove the wall module from its subbase:
1. Locate the two snaps on the bottom of the IFC .
2. Push a screwdriver into each snap to release the IFC
from the subbase.
3. Pull the wall module up and away from the subbase.
See Fig. 8.
WALL
Setting the Wall Module Bus Address Dial
Each wall module on a Sylk bus must use a different bus
address, and there may be multiple TR40/42s wired on a
single Sylk bus. To change the bus address of a wall module,
adjust the address dipswitches to match that of the desired

POWER UP
After the wall module is properly wired to the controller, it will
power up. Upon initial power up, the wall module’s LCD panel
displays three screens for two seconds each, shown in Figs.
9-11, while the configuration file is being loaded. Once the
configuration file has been loaded and the startup screens
have cycled through, the LCD panel will then display the home
screen. If these screens continuously cycle, this indicates
there is no program downloaded to the controller, or the bus
addresses don't match between the wall module and the
workbench config tool.
For Spyder/Niagara tool users, refer to the TR40/42/TR40/42
Plus LCD Wall Modules Operating Guide (Form 63-2741) to
configure and load the desired user interface and parameters
into the wall module.
For ComfortPoint™ Open users, the user interface and
parameters are downloaded automatically from the
ComfortPoint Open controller. There is no configuration required
at the wall module.
