Zio® Lite TR40/42 LCD and non-LCD Wall Modules
INSTALLATION INSTRUCTIONS
BEFORE INSTALLATION
—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.
Fig. 1. LCD Wall Module.
CAUTION
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.

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.
CAUTION
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.

aFor Spyders, use the Resource Usage View in the Spyder Tool to determine the maximum number of devices. For ComfortPoint™ Open controllers, there is a maximum of 3 TR40/42s.
bAs a rule of thumb, single twisted pair (2 wires per cable only), thicker gauge, non-shielded cable yields best results for longer runs.
cThe 30 m distance for standard thermostat wire is conservative, 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.
dThese distances also apply for shielded twisted pair.
