Smart Devices Overview

Lennox Smart Room Sensor

• This device collects room temperature, humidity and occupancy status and passes this information to the S40 Smart Thermostat.

• When replacing batteries it is highly recommended to always use lithium batteries. When using lithium batteries the estimated battery life is two years.

• Maximum unobstructed view of smart device signal under ideal conditions is 70 feet (21.3 meters). Maximum range could be affected by the number of walls or floor and other obstacles which the signal has to penetrate.

• Maximum unobstructed distance for the occupancy sensing capability is 20 feet (6.1 meters) and maximum width pattern of 110º at a mounting height of five (5) feet (1.5 meters) from the floor.

• The thermostat uses an algorithm to calculate average room temperature based on room occupancy / temperature sensor input along with the thermostat’s built-in sensors.Where N is the number of smart room sensors in-stalled.

• The Smart Room Sensor sends data to thermo-stat in 2 to 20 minute intervals to preserve battery life. The update rate is faster if rapid temperature changes are detected. Otherwise, the average sampling rate is every two minutes and a transmis-sion rate is every 30 minutes.
  NOTE: It could take 2-10 minutes to report initial temperature data after adding the smart device to the smart devices network. The farther the smart device is from the S40 Thermostat, the longer it may take.

• Dimension: 4″ x 5.5″ x 3″ (102 x 140 x 76 mm)

• Weight: 4.24 ounces (120 grams) without batteries installed.

• Temperature Range:

  • » Display on thermostat: 40 to 100°F (5 to 37°C)
  • » Sensitivity: +- 1°F (+- 0.5°C)
  • » Operating range: 32 to 130°F (0 to 55°C)

• Humidity Range:

  • » Display on thermostat: 20% to 90% RH
  • » Operating range: 5% – 95% RH (non-condensing)
  • » Sensitivity of +- 5%

IMPORTANT
The Lennox Smart Room Sensor is not a zoning product and will not solve problems related to poor duct work and incorrect equipment sizing.

Lennox Wireless Extender

• Extends the effective smart devices network range.
• Powered by 120VAC outlet.
• Dimension: 4″ x 5.5″ x 2.5″ (102 x 140 x 64 mm)
• Weight: 4.24 ounces (120 grams)

Installation Considerations

Smart Room Sensor
If at all possible it is recommended that all Smart Room Sensors are installed on a wall. This ensures the device will not be lost or accidentally damaged.
Consider placement when addressing the occupancy sensor detection pattern (see page 19).
If used with the provided stand, it is recommended that the Smart Room Sensors is placed on a book-shelf or desk out of reach of children or pets.
Do not install the Smart Room Sensors where it can be affected by:

• Drafts or dead spots behind doors and in corners
• Exterior entrances or interior doors
• Heat generating equipment such as kitchen appliances
• Hot or cold air from ducts
• Radiant heat from sun or appliances
• Direct sunlight
• Concealed pipes and chimneys
• Non-conditioned areas such as an outside wall behind the sensor

Another consideration is smart device signal strength interference by physical objects and materials. The type and thickness of the material can affect how much interference is induced. One or more of the fol-lowing can interfere with the smart device signal:

• Large metal objects and appliances like filing cabinets, metal doors, and refrigerators.
• Floor and ceiling plenum spaces featuring joists, plumbing, duct work, and other materials.
• Plaster, concrete, and specialty glass such as bulletproof or shatterproof glass.
• Water, brick, and marble materials.
• Wood, glass, and synthetic materials like plastic.

The Smart Room Sensors will indicate if adequate signal strength is present (see “Table 1. Sensor – Three Color Descriptions” on page 8). In case of a weak signal, the Lennox Wireless Extender can be used to improve the smart room sensor’s signal strength and thus limit the impact of interference by these sources.
Wireless Extender

Considerations are the same as for the Smart Room Sensor plus a wall outlet in a optimal location for best performance.

Smart Devices Installation

Smart Room Sensor
PLACEMENT

• Locate the desired location for the Smart Room Sensor.

• If the Smart Room Sensor is out of range of your S40 thermostat (approximately 70 feet (21.3 meters) a blue light on the device will indicate so with the blue light flashing every five (5) minutes) and a message will be displayed for the device on the My Home menu option.

• Move device closer to the S40 thermostat or add an Lennox Wireless Extender between the sensor and thermostat.

• For wall placement, install room sensor at a minium height of 5 feet (1.52 meters) on an interior wall. See “Wall Mounting” on page 15 for illustration example.

• Use the provided wall template when mounting sensor to the wall.

• For sensor desktop/table placement use the provided stand.

• For effective temperature sensing, mount the sensor in a location enabling it to sense the general room environment. The sensor must NOT be:
  » Blocked from normal air circulation by ob-structions (e.g., behind curtains or cubicle walls).
  » Exposed to artificial heat sources (e.g., lights, computers, copiers, or coffee makers) or to sunlight (at any time of the day).
  » Exposed to direct sunlight.
  » Exposed to drafts from windows, doorways, diffusers, or returns.
  » Exposed to air flow through the conduit (e.g., from leaks in plenum ducts) or other holes into the wall cavity.
  » Mounted on an exterior wall.
  » Mounted on or near a large thermal mass (e.g., a concrete block wall).
  NOTE : The above factors primarily affect temperature sensing, but some also affect accurate humidity and occupancy sensing as well.
  If the device is out of range of your S40 ther-mostat a blue light will turn on.

• For effective occupancy detection, determine a location that will maximize the area of detection in a room.
  » The smart room sensor occupancy detec-tion function has a 100 degree horizontal span and a 32 degree vertical span. Improper placement may limit the area of occupancy detection for the sensor.
  » Large rooms may require more than one sen-sor to ensure occupancy detection. Please see “Figure 9. Occupancy Sensor Detection Pattern Examples” on page 19 for ex-amples of optimal mounting locations for the smart room sensor.

WALL MOUNTING

1. Confirm that the desired smart room sensor location has good signal strength.

2. Select wall location for sensor installation.

3. Use the provided wall template along with a field-provided leveler tool for proper horizontal alignment on the wall before marking the mounting holes.
   NOTE: The distance between the mounting points is 3/4″ (19mm).

4. Use the provided screws and wall anchors (for drywall applications) if needed.
   NOTE: Screw depth adjustments may be required  in order to accommodate a snug fit for the sensor when attaching to the wall.

USING SMART ROOM SENSOR STAND
If the stand is used, then the smart room sensor should be placed out of reach of children or pets. Possible locations can include a book shelf or a desk. Wall mounting the sensor is preferred to avoid poten- tial loss of or damage to the smart room sensor.
