Lennox Thermostats

As we look back at 2020, we are all reflecting on the year that was, and what we have learned from it. In the HVAC space, the year provided us with opportunities for growth and change, as we adjusted to our “new normal.” Here’s a look at some of the HVAC trends we see happening now taking hold as we head into 2021. Advancements and applications in indoor air quality - especially in HVAC space (SF / MF / CRE) 2020 was filled with starts and stops with regards to innovation. Covid-19 halted work in some facilities altogether earlier in the year. The pandemic has brought with it a re-energized interest in the air quality around us, especially in the public sector. There has been a newfound imperative in creating indoor air quality solutions that ensure that air is circulated, sanitized and purified to reduce the likelihood of the spread of sickness. This is a massive issue and 2021 will see growing efforts in these areas and the increased introduction of systems that will purify air quality. HVAC building systems Continued push toward energy efficiency (mainly SF but also CRE) Energy efficiency will be an ongoing issue into the foreseeable future. Once we have looked back at 2020’s carbon emission reductions (because fewer people were flying and driving) there will be no turning back. The same can be said for HVAC. Increased efficiency will continue to be an ongoing pursuit in 2021 and beyond. On average, HVAC appliances consume 48% of a household’s total energy usage. The latest generation of smart thermostats that use the newer 410A refrigerant have brought about reduced energy consumption by up to 35% optimizing how HVAC building systems are operated (reducing the possibility of leaving the AC on too long, and when it’s not necessary to use). convenience and energy savings Increase in supply chain management / platform services HVAC services such as those that collect and manage data including HVAC unit age, efficiency and condition at the property and portfolio level will continue to see increased adoption. These convenience and energy savings they provide is being seen in the multi-family and commercial space, especially with some building owners having been grounded by the pandemic in 2020. New construction had a role in expanding interest in HVAC asset tagging and helping it gain traction in the industry The data gathered by these services can be used in the future to predict HVAC system failures with significant accuracy before they happen. The convenience and potential cost savings acquired by implementing these services will continue to push their popularity into 2021. Additionally, it is interesting to note that new construction in 2020 had a role in expanding interest in HVAC asset tagging and helping it gain traction in the industry. Cataloguing HVAC assets ensures the follow up and guarantees that warranty registration holds and can help track future maintenance during a hold. At the time of sale, the current owner can present true data of the maintenance of these systems, which can increase the current value of the property and can also be used as a tool in negotiation. performing regular maintenance Remote monitoring can be the end to end solution that completes the action behind the alert (CRE mainly) Remote monitoring will continue to see adoption in 2021. Service providers will continue to rely less and less on clients identifying and reporting a problem a heating/cooling issue. The complaint from the tenant may come in some hours after the problem actually starts, and then by the time they get a service request completed, several hours more. And by the time the contractor is on the scene, it is likely more time has elapsed. Remote monitoring also results in regular maintenance, extending the lifetime of a HVAC system. By proactively performing regular maintenance, the overall costs of maintaining a system can be reduced by 40 percent, in addition to ensuring that units are always using the least amount of energy necessary. seamless customer experience Consolidation of HVAC services and equipment - the way people buy - turnkey integrated services One stop shopping for HVAC services and equipment gained popularity in 2020 One stop shopping for HVAC services and equipment gained popularity in 2020 and we will continue to see increased traction in 2021. There are many reasons why developers what to buy equipment directly from the manufacturer, such as convenience, working with a supplier because of its reputation, cost and guarantees on product and services. As more developers buy equipment directly, these manufacturers are responding by helping out with mechanical drawings. This process cuts down the supply chain, allows certainty that correct equipment is quoted, and saves money. The HVAC industry is also turning the corner in becoming more proactive in remediating failing assets and contractors are redoubling their efforts to provide a seamless customer experience increasing customer satisfaction for multi-family communities as well as other means of optimization of services that positively impact tenants, helping increase retention. HVAC providers that can manage the entire process from installation, to job request to invoicing, even reporting and tracking for each job, will be increasingly in demand in 2021.

Inverter driven air conditioning is more energy efficient, cheaper to operate and more profitable to install than its non-inverter driven equivalent. Here Neil Ballinger, head of EMEA at automation parts supplier EU Automation, explains how HVAC engineers can maintain the inverters in their customer’s aircon units. Do you remember cross country at school? It was exhausting; miles of seemingly pointless jogging and sprinting and, if the teacher was not looking, walking. If you were unlucky enough to be born before modern safeguarding measures were introduced, it probably also meant getting lost in the nearest woods.Why isn’t every installation an inverter driven unit, instead of the traditional single stage or dual stage models? My PE teacher, who seemed particularly vicious at the time, but in retrospect just knew about sports science than most, used to make us do something called fartlek as well. This meant long distance runs, incorporating elements of speed training by mixing up sprints with jogs and walks. The worst bit was starting to run again after a walk. That is exactly how the motor in your customer’s air conditioner feel if the units you fit are not inverter controlled. The motor has to act just like a runner doing fartlek — it sprints continuously, operating at full speed until the thermostat tells it the room is cool, then it stops. When the room gets warm, it starts again, powers immediately up to full speed and repeats the process indefinitely. Just like a teenage cross-country runner, it is the starting and stopping that is the tough bit. Furthermore, the unit probably doesn’t have to run at full speed to keep the room at the correct temperature, if the motor were inverter controlled it would speed up and slow down as the temperature fluctuates. Why isn’t all aircon inverter driven? We all know that inverter driven aircon is better than its non-inverter driven cousins. It can provide heating as well as cooling and the lifetime cost of use is less for the customer — because their energy bills stay low. The cost of installation is also higher because it is a more complex job, so it works out better for the contractor. It’s a win-win. The research firm Technavio even lists it as one of the key technologies driving growth in the HVAC market in its annual reports every year. So, the only question is, why isn’t every installation an inverter driven unit, instead of the traditional single stage or dual stage models?When contractors contact EU Automation to buy automation parts, for the units they maintain, they have given us another reason: maintenance Cost is a factor, but when contractors contact EU Automation to buy replacement motors and inverters, and other automation parts, for the units they maintain, they have given us another reason: maintenance. As HVAC engineers, we are not necessarily specialists in power electronics, and this makes inverter maintenance daunting. Microcontrollers and IGBTs (Insulated Gate Bipolar Transistors) are not beyond us by any means, but they can be intimidating. Personally, I would back an electrical or heating engineer over an electronics specialist in a problem-solving contest all day long; but that doesn’t solve the problem at hand. Furthermore, while we are experts in air conditioning brands, and know our Daikins and Grees from our Mitsubishis and Fujitsus, we don’t necessarily have contacts at the inverter manufacturers. Amtech, Danfoss, Vacon and Yaskawa are all names we know, but the local dealer for any of them is probably not in your phone book. This is especially true if the unit you need is from a first-generation inverter driven aircon unit and well over a decade old. While we are experts in air conditioning brands, and know our Daikins and Grees from our Mitsubishis and Fujitsus, we don’t necessarily have contacts at the inverter manufacturers Maintenance techniques While inverter maintenance can be daunting, it isn’t difficult. The tools you will need most often are nothing more than a rag and a spanner, while the more esoteric kit is stuff you probably carry anyway, a laptop, vacuum and a Fluke meter. Before you start, remember that while we tend to refer to an inverter as an inverter, the manufacturers themselves, and many of the sources of information online, often refer to them as VSDs (Variable Speed Drives), VFDs (Variable Frequency Drives) or just plain old drives. As a result, when you are searching online for a video to explain something, it’s worth using all three of those terms, alongside the inverter manufacturer’s name and the problem to make sure you get the right result.While inverter maintenance can be daunting, it isn’t difficult When you do move on to maintenance, step one is simple; make sure that the unit is free of dust. This is as easy as vacuuming the heatsink with an ESD (Electrostatic Discharge) vacuum cleaner when you perform routine maintenance or investigate a problem. While you are checking for build up of dust and daily grime, check the filters. They will probably have to be replaced during annual maintenance, but high use might mean they need to be replaced more often. The control panel itself should be well ventilated and free of dust as well, if it isn’t it can overheat, which is the number one cause of inverter damage and the most common reason contractors contact us for replacement units. Before you put your vacuum and duster away, you should make sure that the inverter unit’s location is clean and as sheltered from the elements as possible. Because it’s normally situated on a roof, it’s not going to be perfect, but the units are designed to take a limited battering. That doesn’t mean it’s okay for them to be covered in leaves, surrounded by rubbish or immediately beneath the guttering outlet though! Before you put your vacuum and duster away, you should make sure that the inverter unit’s location is clean and as sheltered from the elements as possible Get out the spanner Once you’ve finished these steps, you are done with dusting for now, it’s time to get out your screwdriver and your spanner. Step one is to make sure the fans on the inverter are operating normally, without noise and with nothing blocking their rotation. The fan keeps the internal components running effectively, just as it does on PC, and if its function is impaired the capacitors will overheat and the inverter will fail.When you install or maintain an inverter on an air conditioning system, it is a sensible precaution to back up the drive parameters to your laptop The next job is to grab your spanner and make sure the power terminals are on tight. Loose connections cause arcing, overheating and even melting of components and are easily checked during any kind of maintenance and repair. While we are still in the realms of the work your apprentice can do with their eyes closed, you should also make sure that the inverter’s removable LCD control pad is stored sensibly and not continually attached to the drive. If it remains attached, there is a chance the display will stay on permanently, which means that when you need it to diagnose a problem, it will probably already be burnt out. Break out the laptop When you install or maintain an inverter on an air conditioning system, it is a sensible precaution to back up the drive parameters to your laptop. It takes minutes and is normally done by using the removable LCD control. In fact, it’s often as simple as selecting ‘PARs’ and then ‘BACKUP’ from the menu. If you struggle, there are lots of videos on YouTube, like this one, which explain the process for each drive. As a result, if the inverter ever does need replacing, you can whip out your backed up parameters and order a new or refurbished one easily, before reloading the parameters to the replacement and getting up and running in no time. Your customers will think you are a power electronics genius, as well as a HVAC expert, and they will be loyal for life; especially of you save them on a hot day! If you follow these simple measures, you will find that the inverters in your customer’s air conditioning units last much longer and no motors will have to run the equivalent of a cross country, thanks to a lack of inverter control.

Sensors have been used in buildings since the invention of air conditioning to understand how buildings are performing, from in-room temperature sensors, to sensors on plant equipment, motors, ductwork and pipes. The Internet of Things (IoT) has enabled more sensors of different types to be deployed in more locations throughout the building easier than ever before. The point of installing and using IoT sensors is to gain deeper insight into how buildings are performing, and ensure buildings are healthier, more productive for people to work in, more effective to run and more energy efficient. This article looks at in-room sensors, such as temperature, air quality and occupancy, and how IoT sensors can help improve building performance. The benefits of IoT sensors is that they are easy to install, both physically and from a commissioning perspectiveThe benefits of IoT sensors is that they are easy to install, both physically and from a commissioning perspective. Cabling is usually minimal or not required at all: IoT sensors are battery powered, or require simple USB power (from a plug socket) or utilise Power over Ethernet (PoE). IoT sensors use low power wireless protocols (such as Bluetooth, Mesh etc) to send data, and thus can be placed anywhere within a building and do not require multiple physical IOs for integration. Unprecedented amounts of data IoT sensors are usually cost-effective such that thousands of sensors can be deployed throughout the building without much effort. This gives an unprecedented amount of data to building managers, which comes with its own challenges – How to make use of this data? There are two ways to utilise this data to improve building health, performance and efficiency: Use an effective monitoring platform or data analysis tools to turn raw data into actionable insights. This can provide the building and facilities team with insights to be more pro-active, and spot temperature, air quality, overcrowding, etc issues even before the users or tenants begin to notice e.g. it’s too cold, too drafty, too stuffy, etc. Integrate the live data from the IoT sensors straight into the Building Management System (BMS) and create new control strategies to automate the building further. This requires a bit more integration and commissioning work upfront, but the performance and efficiency benefits through automation will give a fast Return on Investment. The key here isn’t the sensor integration itself, but the building control strategy that will be the logic to which the building automation fucntions. Some use cases of IoT sensors are: Temperature and HVAC A common problem I’ve heard from many buildings is that existing temperature sensors that connect to the BMS have been placed in the ceiling, and not at head height. Using battery powered IoT temperature (and humidity) sensors, and sticking them to the wall at head height, is a quick and easy way to measure temperature where it actually matters.Data can be used to plot temperature heatmaps, find hot or cold spots, or analyse the solar heat gain Data can be used to plot temperature heatmaps, find hot or cold spots (e.g. if two nearby FCUs are working against each other, one heating one cooling); or analyse the solar heat gain, and adjust internal loads. The IoT temperature sensors can be connect to the BMS to provide more accurate temperature data to FCUs instead of the sensors in the ceiling. In general, IoT senors can easily be reconfigured and moved, e.g. during a fit out. But care needs to be taken to keep a close eye on the sensors and which room/space they relate to. Battery will need to be changed every 5 years. The IoT temperature sensors are cheap enough that they can simply be replaced with new ones e.g. the sensors element need recalibrating. Indoor air quality sensors and HVAC Accurate CO2 level sensors (which use duel channel NDIR technology) with IoT connectivity are getting cheaper and can also be used to do ‘heatmapping’, of the building, and provide accurate insights on indoor air quality. Similarly, heatmaps can be done with particulate matter sensors (PM10, PM2.5, PM1), VOC sensors and others embedded in an IoT connected sensor. CO2 level sensors in Accurate CO2 level sensors  with IoT connectivity are getting cheaper and can also be used to do ‘heatmapping’particular are important as the level of CO2 indoors affects our cognitive ability. High indoor CO2 levels hinder our productivity. Indoor CO2 levels of 900ppm to 1400ppm and higher, which are seen in buildings with poor ventilation, reduce our ability to make decisions and use complex information by 15% to 50% and higher, respectively. Indoor CO2 levels are also a good indication of the risk of infection, as people breathing are usually the main source of CO2 in buildings. So being able to monitor CO2 levels in every space inside the building will provide building owners, tenants and users with reassurance with regard to COVID-19 related challenges. ‘eCO2’, a derivative from VOC sensors, should NEVER be used as a measure of CO2 levels. All CO2 sensors elements need to be recalibrated every 3-5 years. Occupancy level and HVAC Knowing the occupancy on every floor of the building can be used to control HVAC systems. Through BMS integration, controlling the flow of ventilation dynamically, based on real-time floor-by-floor occupancy, allows the building to ‘breathe’ with actual demand.Employing an occupancy-based, dynamic control strategy on the BMS reduces the energy consumption for buildings that rarely see full occupancy This balances the building from a technical perspective, and improves air delivery by opening up more ventilation capacity. Employing an occupancy-based, dynamic control strategy on the BMS, not only improves the indoor air quality, but also reduces the energy consumption for buildings that rarely see full occupancy, or have dynamic use (which will only be more common as we begin to work-from-home more often) Measuring the number of people is difficult, which usually means expensive. One way to count people is using PIR sensors places under each desk. This can get expensive for 1,000 desks even if one IoT PIR sensor is relatively cheap. Another way is to use a less accurate, but cheaper method, e.g. using long-range sensors that count the number wireless devices in a vicinity / floor, and using that as a proxy for percentage occupancy levels. Summary 1,000s of IoT sensors can be easily installed anywhere throughout any building. To get the best out of an IoT system a clear use case (or set of use cases) is necessary. By understanding the use cases and benefits, the right design, UI or integration can be used to maximise the cost-benefit ratio for the specific use cases, for example: BMS integration for IoT temperatures sensors; Relevant platform UI and analysis to extract actionable insights for the Facilities Management team from the raw IoT sensor data; or Correct HVAC control and automation strategy based on occupancy level data.

LENNOX EMEA, a company in the design and manufacture of heating, air conditioning, air treatment, and refrigeration equipment, through its three brands Lennox, Friga-Bohn, and HK Refrigeration, is hosting a content-rich ‘Learning Month’, which will run from April 15th to May 15th. Learning Month will comprise a series of free online webinars (in local languages) that provide professionals in the HVAC-R (Heating, Ventilation, Air Conditioning, and Refrigeration) industry with targeted insight and strategy to take their skills to the next level. Regulatory changes Among the primary ambition of these enlightening webinars is to provide information and guidance on new industry developments and trends.

The differences between the two solutions, along with best-practice selection criteria, 1/2 will help installers, engineers, and end-users grasp the fundamentals required to reach the optimum decision. This webinar is available in German and Dutch. Ultimately, knowledge provides many opportunities, not least the chance to make astute selection decisions, optimize refrigeration and HVAC units for performance and efficiency, and become a source of advice and expertise. All those participating in any of the webinars at Learning Month will also get the opportunity to ask questions of the respective Lennox HVAC-R specialist.

As the Internet of Things (IoT) has evolved, the need has become obvious for stronger unity among brands and ecosystems to enable products within smart environments to work together more easily. Working to serve that need is the Zigbee Alliance, which seeks to promote collaboration in the Internet of Things by creating, evolving, and promoting universal open standards that enable all objects to connect and interact. Their effort took off when Amazon, Apple, Google and the Zigbee Alliance announced an industry working group in December 2019 to take the “best of market” technologies from leading smart home standards, portfolios and ecosystems and to develop a “super spec” that will be open, inclusive and a significant industry shift in the smart home market. smart home automation system “Zigbee Alliance has been for a while now working on openness and interoperability, which has led us to the Project Connected Home over IP (CHIP), which is looking to unify the environment, under one technology, one certification program and one logo,” says Chris LaPré, Zigbee Alliance’s IoT Solutions Architect. “It really does fuel IoT possibilities, whether in HVAC or any other sectors.” There is a stronger need for unity, which is why we are developing Project Connected Home over IP" Project CHIP is a royalty-free connectivity standard that unifies brands and ecosystems into a single smart home automation system that operates any other technology based on Internet Protocol (IP). The intent is to simplify product development for device manufacturers, broaden consumer choice, and to ensure easy discoverability, deployment and engagement to fuel connected living. unifies that environment “We have noticed that, as the IoT has evolved, there is a stronger need for unity, which is why we are developing Project Connected Home over IP,” says Jon Harros, Zigbee Alliance’s Director of Certification and Testing Programs. “It fits with the Zigbee Alliance’s goal to unify systems, and to focus on everyone using the same application at the top. It unifies that environment, whether you are integrating your system with Amazon Echo devices or connecting to Google Home.” Participating in development of Project CHIP are 125 companies of various types from around the world working together with more than 1,100 of their experts serving across sub-committees to formulate specifications and fine-tune the project. Although the technology is being developed for the home market, the specifications have been formulated with an eye toward expanding into the commercial market in the future. home system technologies Development of open, interoperable systems provides greater freedom for consumers to choose among the many technology choices on the market, without being tied to a single brand or ecosystem. Zigbee Alliance certifications and memberships span the globe, with roughly a third in Europe, a third in North America and a third in Asia. Involvement in Europe is slightly higher than the other regions. Alliance members represent manufacturing sites all over the world. Project CHIP is a newer initiative of the Zigbee Alliance, which previously developed Zigbee Pro to enable home system technologies to operate using IEEE 802.15.4 wireless signals on the 2.4GHz radio band over a self-healing true mesh network. The original Zigbee protocol is used for many applications around the world, including HVAC. smart temperature devices HVAC developers who have specific use cases should have a look at the work of the alliance Members of the Zigbee Alliance include HVAC companies such as Lennox, Stelpro and Belimo, among others. Carrier is a recent company that has joined the Zigbee Alliance. Smart thermostats, including the popular Ecobee, have used the Zigbee protocol. More than 100 different devices have been certified as thermostats or smart temperature devices.  Harros urges other HVAC companies to become more involved with the Alliance. “We want them to come and have a look to see what we are doing and get involved,” he says. “This is where the work is being done as we unify the environment and bring together all the devices and ecosystems to work together.” HVAC developers who have specific use cases should have a look at the work of the alliance, he adds. certification transfer program Among the strengths of the Zigbee Alliance are years of experience certifying products, which includes testing them and confirming that they comply with the promoted specifications and functionality. The specifications are open standards that are developed in cooperation with all the companies that are Zigbee Alliance members. Another route is the certification transfer program, in which a company chooses a certified white-label product, becomes a member of the Alliance, and then rebrands the product while retaining the certification. “It helps them get products on the market quickly while they build their own knowledge base,” says Harros. "All our work is focused on standardizing the behavior and functionality of products and making sure everyone is following the same standard to get interoperability,” says Harros. “Members all contribute to the standards.”

Challenged to propose a creative summer energy savings tip, Kortney Gaura of Le Claire, Iowa, chose to implement "Anything Can Happen Sundays" in her household, and her submission led her to be named Lennox’ newest "Energy Savings Superstar." The Lennox 2018 “Energy Savings Superstar” Contest offered an opportunity for consumers to think about how they devote their time and energy, and invited them to suggest simple but creative solutions for saving money on their energy bills during the steamy summer months. Gaura’s idea of filling a jar with several energy conserving tips to be implemented as a family created an opportunity for her family to spend more quality time together and save energy at the same time. home comfort solutions This is exactly the type of energy- saving advice Lennox Industries, a renowned provider of innovative home comfort solutions, was looking for when it launched the North America contest, which ran from July through August. "This year, we received hundreds of original yet innovative and creative submissions; however, Kortney Gaura suggested a relatable tip that can easily be implemented in any household wanting to save money and energy, while creating an opportunity for more family time," said Brittani Youman, Energy Efficiency Expert at Lennox. indoor air quality products Participants were encouraged to be clear, creative and above all, have fun with their submissions "Since Lennox is a recognized leader in energy-efficient heating, cooling and indoor air quality products, the Gaura family can rest easy knowing they are receiving world-class Lennox innovations that will maximize their energy savings and will keep them cool for many summers to come."
