Installation—Controls
Height Requirements
It is recommended that you mount the back plate a maximum distance of 54 inches above the floor.
If a parallel approach by a person in a wheelchair is required, reduce the maximum height to
48 inches.
Note: Consult section 4.27.3 of the 2002 ADA (Americans with Disability Act) guideline, and local
building codes, for further details regarding wheelchair requirements.
Mounting Surfaces
Using the hardware provided, mount the back plate of the sensor to a flat surface such as sheetrock
or plaster, or an electrical junction box. The sensor must be mounted plumb for accurate
temperature control and to ensure proper air movement through the sensor.
• If mounting onto sheetrock or plaster, use the plastic threaded anchors (pre-drilling holes is not
usually necessary) and the two M3.5 x 20 mm mounting screws.
• For mounting onto an electrical junction bo
x, use the two 6-32 x 3/4 in. screws.
Before beginning installation, consider the location con
siderations below. Also, refer to the unit
wiring schematic for specific wiring details and point connections.
Location Considerations
Avoid mounting the sensor 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, fir
eplaces, appliances, etc.
• Airflow from adjacent zones or other units.
• Unheated or uncooled spaces b
ehind the controller, such as outside walls or unoccupied
spaces.
• Concealed pipes, air ducts, or chimneys in partition spaces behind the controller.
Fan Mode Switch Installation
The fan mode switch ships loose inside the unit accessory bag. Follow the steps below to install
the fan mode switch.
Items needed:
2 x 4 electrical junction box
1. Remove the brown wire if not using a field-supplied damper.
2. Remove the terminals, cut and strip wire
s as required for installation.
3. Level and position a 2 x 4 electrica
l junction box.
4. Follow the instructions given in “Wall-Mounted Control Interconnection Wiring,” p. 60 and
route the wires as shown in the wiring diagram. R
efer to the typical wiring diagram or to the
unit specific diagram on the unit.
5. Position the fan mode switch over the junction bo
x with the two screws supplied.
Wired Zone Sensor Installation
Follow the procedure below to install the wired 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 mount the sensor back plate:
