Installing Wall Mounted
Controls
Wall mounted zone sensors ship taped to
the control box.
Position the controller on an inside wall
three to five feet above the floor and at
least 18 inches from the nearest outside
wall. Installing the controller at a lower
height may give the advantage of
monitoring the temperature closer to the
zone, but it also exposes the controller to
airflow obstructions. Ensure that air flows
freely over the controller.
Before beginning installation, follow the
wiring instructions below. Also, refer to
the unit wiring schematic for specific
wiring details and point connections.
Wiring Instructions
Avoid mounting the controller in an area
subject to the following conditions:
• Dead spots, such as behind doors or in
corners that do not allow free air
circulation.
• Air drafts from stairwells, outside
doors, or unsectioned hollow walls.
• Radiant heat from the sun, fireplaces,
appliances, etc.
• Airflow from adjacent zones or other
units.
• Unheated or uncooled spaces behind
the controller, such as outside walls or
unoccupied spaces.
• Concealed pipes, air ducts, or chimneys
in partition spaces behind the controller.

Installation
Zone Sensor Installation
Follow the procedure below to install the
zone sensor module.
1. Note the position of the setpoint
adjustment knob and gently pry the
adjustment knob from the cover
using the blade of a small
screwdriver.
2. Insert the screwdriver blade behind
the cover at the top of the module
and carefully pry the cover away
from the base.
3. To install the zone sensor module
without a junction box (directly to the
wall):
a. Using the module base as a
template, mark the the rectangular
cutout for the control wiring and
module installation holes. Ensure the
base is level.
b. Set the base aside and make the
3
cutout. Then, drill two / " diameter
16
holes approximately one-inch deep.
Insert and fully seat the plastic anchors.
c. Pull the control wires through the
cutout and attach the module to the
wall using the screws provided.

4. To install the zone sensor module to a
standard junction box:
a. Level and install a 2" x 4" junction
box (installer supplied) vertically on
the wall.
b. Pull the control wires through the
cutout. Attach the module to the wall
using the screws provided.
5. Strip the insulation on the
interconnection wires back 0.25 inch
and connect to TB1. Screw down the
terminal blocks.
6. Replace the zone sensor cover and
adjustment knob.
If installing a Tracer AH540 zone sensor,
see the Tracer Summit Communication
section for more information.
