Reference Figure 25 on page 38 when installing the wall mounted
zone sensor.
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 cutout. Then, drill two 3/16
inch diameter holes approximately 1 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 inch x 4 inch 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.
Before beginning installation, follow the wiring instructions in the “Wall
