Installation—Sensors

UV-SVN03F-EN 31

• Areas that are close to heat sources such as sunlight,

appliances, concealed pipes, chimneys, or other heat-

generating equipment

• Drafty areas

• Dead spots behind doors, projection screens, or

corner

• Walls that are subject to high vibration

• Areas with high humidity

• High traffic areas (to reduce

accidental damage or

tampering)

• Metal barriers between the receiver and the sensor (for

example, plastered w

alls with metal lathe or metal roof

decks)

• Thick, solid concrete walls between the receiver and

the sensor

• Placing the sensor inside metal enclosures

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 box, use the

two 6-32 x 3/4 in. screws.

Before beginning installation, consider the location

nsiderations 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 do

ors or in corners that do

not allow free air circulation.

• Air drafts from stairwells, outside doors, or

sectioned hollow walls.

• Radiant heat from the sun, fireplaces, appliances, etc.

• Airflow from adjacent zones or other units.

• Unheated or uncooled spaces behind the controller,

suc

h as outside walls or unoccupied spaces.

• Concealed pipes, air ducts, or chimneys in partition

aces behind the controller.

Location Considerations for Wireless zone

sensors

Placement of the sensor is critical to proper operation (the

receiver is factory mounted on fan-coil units). For most

installations, barriers limit proper radio signal strength

more than distance. For best radio transmission range and

reliability, mount the receiver and sensor in line of sight.

Where this is not possible, try to minimize the number of

barriers between the pair of devices. In general, sheetrock

walls and ceiling tiles offer little restriction to the

transmission range for the sensor is as follows:

• Open range: 2,500 ft (packet error rate = 2%)

• Usable range: 200 ft

• Typical range: 75 ft

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 wires as required

r installation.

3. Level and position a 2 x 4 electrical

junction box.

4. Follow the instructions given in “Wall-Mounted

Control Interconnection Wiring,” p. 42 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 box

with the two screws supplied.

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 behi

nd the cover at the top

of the module and carefully pry the cover away from

the base.

3. To mount the sensor back plate:

a. Hold the back plate against the mounting surface

and ma

rk the screw locations.
