Introduction
This guide can be used by the installer to create the smart devices network and add, replace and remove a Lennox Smart Air Quality Monitor. Lennox ® S40 Smart Thermostat This thermostat is the smart device network host for Lennox smart devices. This Lennox S40 Smart Thermostat will be referred to throughout this document as thermostat. Lennox ® Smart Air Quality Monitor (SAQM)

• The device collects data on Carbon Dioxide (CO2 ), Particulate Matter (PM2.5 ) and Volatile Organic Compounds (VOCs). The device then transmits to the thermostat which analyzes the data and displays it on the thermostat’s display.
• Continually monitors indoor air quality and sends data to thermostat once every minute.
• Unit is powered typically by either a separate 24VAC transformer installed at the indoor unit or a plug-in type 24VAC transformer.
• Only one (1) device is supported per single S40 thermostat smart devices network.

This application is used to manage the S40 thermostat smart devices network (adding, removing and renaming the device.

Terminology

Table 1. Terminology

Term|

Definition

---|---
PM2| PM stands for particulate matter (also called particle pollution), the term for a mixture of solid particles and liquid droplets found in the air you can breath. The 2.5 is the fine inhalable particles, with the diameters that are generally 2.5 micrometers and smaller. Breathable air particles can include pet dander, bacteria, mold, chemicals from cleaning products, building materials, fuel-burning equipment such as furnaces, upholstered goods, cooking, sweeping, copy machines, skin flakes, clothing fibers, combustion, smoke, dust, dirt, spores, and pollen. Sources vary seasonally.
VOC| Volatile organic compounds (VOC) are a combination of gases and odors released/emitted/off-gassed from a variety of sources. VOC include a variety of chemicals, some of which may have a short- and long-term adverse health effects. Alternate terms are
odors, gases, vapors and chemicals.

Table 1. Terminology

Carbon dioxide is a by-product of combustion, as well as a result of the metabolic process in living organisms (for example, you remove it from your body via the lungs in exhaled air).
BLE| BLE stands for Bluetooth Low Energy. BLE is a variation of the Bluetooth wireless standard designed for low power consumption.

Installation Considerations

If the desired installation location for the SAQM is not within range of the thermostat, then a
Lennox Wireless Extender (22V26) can be used to increase the effective range of the network.
Do

• Read this entire document, noting which procedures pertain to your specific equipment and system requirements.
• Conform to local and national building and electrical codes and ordinances.
• Installed SAQM a minimum of 5 feet (1.50 meters) up from the floor.
• Install on a wall with a minimal distance six (6) inches (154mm) from the S40 thermostat.
• Install in a common area for air sampling.

Do Not

• Install on voltages higher than 30VAC.
• Install in direct sunlight.
• Install near discharge air vents.
• Install near fireplaces or other heat sources.
• Install on exterior walls.
• Install near windows or doors.
• Install near kitchens.
• Install in rarely used rooms or hallways.

Overview

Data Collection
The device collects data on fine particles (PM2.5),VOCs and CO2. For further details, see “Table 1.
Terminology” on page 4 for full descriptions.
The device then transmits this data through smart devices network to the thermostat which analyzes the data and displays it on the thermostat.
When the side switch is set to the DOWN position it will turn off the internal fan and stops sending data to the S40 Smart Thermostat. Setting the side switch to the UP position will restore all functions. An alert code 70003 is raised and will remain active until the side switch is set back to the UP position.
The SAQM details screen will display the last reading from the device before the switch was changed to the DOWN position.
NOTE: It could take 2-10 minutes to report initial air quality 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. Calculating Data
IMPORTANT
After adding the smart device to the smart devices network, it will begin displaying information from the Smart Air Quality Monitor once there is a blower, cooling, or heating demand. Until the first thermostat demand, the thermostat’s SAQM screen will indicate it is calculating.

Sensor Indicator, Button, Side Switch and Vents Locations

NOTE: Light is only on when there is an issue with signal strength.

low or has lost connection to the thermostat.
•No blue light indicates signal strength is good.
Pairing| GREEN| A flashing green light indicates the unit is in pairing mode.

See “Table 5. Lennox Smart Air Quality Monitor Alert Codes” on page 19 for a complete list of alerts applicable to these smart devices that are generated by the S40 thermostat.
Side Switch
The primary reason for this switch is to turn off the internal fan in case the device is installed in a bedroom.
The side switch on the SAQM when in the UP position turns on the internal fan and transmits air quality data to the thermostat.
When the switch is set to the DOWN position it will turn off the internal fan and stop air quality data to the thermostat.
An alert code 70003 will be displayed indicating the switch is OFF. The alert code will automatically clear once the switch has been set back to the ON position.
While the switch is in the DOWN position, the latest reading from the SAQM will be displayed on the thermostat. It will not update that information until the switch is oved back to UP position.
IMPORTANT
The dealer and homeowner may receive an email indicating that Alert Code 70003 is a no cool, no heat condition. This is not true and the HVAC system will operate normally. This type of notification is due to alert code being classified as a Service Urgent.

Installation

Selecting Placement
As previously mentioned, it is recommended that the SAQM is installed near the thermostat. Recommended minimum distance from the thermostat is six (6) inches. This is required so that any heat given off from the SAQM does not affect temperature sensing function of the thermostat.

• A field-provided 24VAC, 1 AMP or greater plugin wall power adapter will be required.
• It is recommended that the SAQM is paired near the thermostat and then positioned in home at the desired installation location.
• Once power is applied to the smart device at the desired location, then check the status of the LED (see “Table 2. Status Indicator – Two Color Descriptions”). Maximum range without an extender is approximately 70 feet (21.3 meters).
• If a blue LED is on, then move the smart device closer to the S40 thermostat or add a Lennox Wireless Extender (sold separately) between the smart device and thermostat.
• For wall placement, install smart device at a minimum height of 5 feet or 1.5 meters on an interior wall. See “Installing on Wall” on page 10 for illustration example.

Confirming Placement Location

1. Take the smart device to the desired location after pairing has been completed (see “Adding SAQM” on page 13 near the S40 thermostat).
2. Apply power to the SAQM.
3. Observe the status of the signal strength LED indicator. If the blue LED comes on, then the smart device is receiving a weak or no signal.
   Either reposition the smart device or add a Lennox Wireless Extender.

Installing on Wall

1. Use the included wall template along with a field-provided level tool for proper horizontal alignment on the wall before marking the mounting holes.

2. Cut or drill 3/8″ hole in wall for R and C wiring.
   Ensure wiring hole is positioned properly in relationship to smart device terminals location.

3. Pull about three inches (75mm) of thermostat wire (18 – 24 AWG) through the opening and remove the outer thermostat wire jacket.
   IMPORTANT
   Seal wire hole in wall to prevent internal wall contaminants from affecting sensors.

4. Strip 1/4” (6 mm) insulation from end of each wire.

5. The other end of the wiring should be routed behind the wall to the thermostat subbase location. Use the provided three-wire splice connectors to connect to the R and C terminals (see “Terminal Designations and Wiring Recommendations” on page 11 for wiring details).

6. Using the provided wall template, drill 3/16” (5 mm) holes at marked locations on the wall for anchors.

7. Then insert wall anchors into holes until flush with the wall.

For drywall applications insert provided wall anchors in holes until flush with wall and then back out for proper height for mounting. Screw depth adjustments may be required in order to accommodate a snug fit for the Smart Air Quality Monitor when attaching to the wall.

Terminal Designations and Wiring Recommendations

Use standard thermostat wiring and a field-provided 24VAC transformer (10P17) or 24VAC wall adapter (18M13) to make the power connections as exampled in the following illustration.
Table 3. Terminal Designations and Wiring Recommendations

for R and C connections

Powering the Smart Air Quality Monitor The following are considerations concerning powering the SAQM.

• Recommend connecting SAQM to the S40 using the provided splicing connectors. Both devices will be powered by the indoor unit transformer as long as no other equipment is attached (see “Figure 4. Using Indoor Unit Power and Connecting at Thermostat” on page 12).
• If additional equipment other than the S40 and SAQM are connected to the indoor unit transformer then an additional transformer is required.
• The additional transformer might be a secondary transformer or a wall plug (see “Figure 3. Separate or Plug-in Transformers”).

Table 4. 24VAC Transformers

Using Indoor Unit 24VAC Transformer Use the provided three wire split connectors to power the SAQM from the thermostat power connections.

Adding SAQM

Considerations

1. Only the S40 Smart Technician App can be used to create the smart devices network. Both S40 Smart Technician and Smart Thermostat Apps can be used to add/remove sensors.
2. When adding or removing the SAQM the S40 Smart Technician or Smart Thermostat Apps (mobile device) will need to be within 10 feet (3 meters) of the thermostat.
3. If the SAQM just added does not appear under the (Equipment List or My Home) screens, then allow a few minutes to pass before checking again.
4. Do not switch back-and-forth between your mobile device’s screens during the adding or removing procedure.
5. If adding a SAQM which will be out of direct range of the thermostat and will connect via a Lennox Wireless Extender, then the Lennox Smart Technician or Thermostat Appsdo not required the user’s mobile device to be near the thermostat for the adding or removing procedure.
6. Always give each SAQM a unique name.
7. After removing a functional SAQM, make sure to perform a factory reset.
8. In case the adding procedure fails, then always perform a factory reset on the SAQM before trying to add it again.
   Adding Smart Air Quality Monitor
