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.
