INSTALLATION
CAUTION
Equipment Damage Hazard.
Electrostatic discharge can short equipment
circuitry.
Ensure that you are properly grounded before
handling the unit.
Touch only the plastic cover, casing, and buttons.
Mount the T7771A 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 waterpipes or near air ducts. Avoid
locations that are exposed to discharge air from registers or
radiation from lights, appliances, 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. 5). When mounting directly on a wall,
use the type of screws appropriate for the wall material.
NOTE: See Fig. 4 for subbase mounting dimensions.

Wiring
Attach the wires from the device sensor terminals to the
appropriate wall module terminals. See Fig. 6.
CAUTION
Improper Electrical Contact Hazard.
Screw type terminal blocks are designed to accept
no more than one 14 AWG (2.5 sq mm) conductor.
Connect multiple wires that are 14 AWG (2.5 sq mm)
with a wire nut. Include a pigtail with this wire group
and attach the pigtail to the individual terminal block.
Wire the terminal blocks 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.
2. If two or more wires are being inserted into one
terminal, twist the wires together before inserting.
NOTE: When two or more wires are being inserted
into one terminal, be sure to twist them
together. Deviation from this rule can result
in improper electrical contact. See Fig. 9.
3. Insert the wire in the required terminal location and
tighten the screw to complete the termination.
4. Verify wall module wiring with Fig. 6.
NOTE: Wire the E-Bus using Level IV 22 AWG (0.34 sq mm)
plenum or non-plenum rated, unshielded, twisted
pair, solid conductor wire.
