Every module arrives wired up, on its own demo page. Double-click a block, and it opens its own window - live status, and every setting. The BACnet Point Builder previews what it would create, and what it would skip. Confirm, and it builds the whole batch. The status line and the health log record what was done - and by whom. Modbus Address Shifter. Conflicts stop the run until they're resolved. Point Rename shows how many points are in scope, then asks you to confirm. Changed your mind? Undo restores them. BACnet Renumber shifts the object instances of a set of points. Confirm, and they're renumbered. Undo puts them back. Global Numeric updates matching values together. And that can be undone too - with a confirmation first. Sequence Stager handles staging and duty rotation across a set of units. Fail a unit on the demo page, and watch the module respond. The next healthy unit is called, and the log records why. Once it's healthy again, it waits for the next duty cycle. On a duty rotate, the next unit proves running before the last one stops. Here's the same module on a twenty-unit rig. Drive Set runs a duty and standby pair, with proof of flow. When a drive trips, the other takes over until the latch is reset. Analogue and register meters keep totals by hour, day, week, month and year. The Meter Bar Chart puts those totals on a graphic.

Drive A is the duty drive. It shows green, and its run hours are counting up as it runs. Drive B is the standby drive - it isn't running, but it's ready to take over if it's needed. Now a trip on Drive A. It turns red, and the fault latches. A latched fault doesn't clear itself when the trip goes away it stays latched, and in view, until someone resets it. Drive B takes over and spins up. The pair keeps running, and nobody had to step in to make that happen. The changeover is automatic. Now the same test, from the wire sheet. A trip is set on Drive A, just as you might set one while you're commissioning the plant. This time you can watch what the module does on the sheet itself, as well as on the graphic. The module's popup is dragged to one side, so you can see the live wire sheet running underneath it. The popup and the sheet stay in step - one is a view of the other. On the sheet, Drive A shows its trip and its failed flow and Drive B is enabled in its place. This is live commissioning. The values on the wire sheet update as it happens, so you can follow every step of the changeover while you test and see that the block has done exactly what you asked of it. https://www.3ec.co.uk/media/films/teclogic/33354384b56e889a-8dc0b216e46f-dark.mp4 153 2026-11-13T00:54:52+00:00 yes no https://www.3ec.co.uk/media/films/teclogic/1eb517d8f21b5d14-d7423c848f04-dark.webp Smart Setpoint - the dial, 16 to 26 Smart Setpoint - the dial, 16 to 26 - This is Smart Setpoint, shown on the large thermostat dial. Its job is to take one setpoint, and work out the heating and cooling setpoints around it. The dial is dragged from 16 degrees up to 26. The colour runs through the full spectrum as it goes from cold at the bottom of the range, up to warm at the top - so the setting reads at a glance. Now watch the heating and cooling band. It follows the setpoint, wherever the dial is set. Move the setpoint, and the band moves with it. Next, the PIR switch is dragged on. A PIR is a presence detector, so the space goes from standby to occupied. The module sees the change straight away. With the space occupied, the deadband narrows around the setpoint. The heating and cooling setpoints now sit closer to it, holding the space nearer the temperature that's been asked for. The dial swings warm, and then cold, and the heating and cooling setpoints follow it each way. The band keeps its shape around the setpoint as it moves. And the PIR switches off again. The space drops back to standby, and the deadband opens out once more. https://www.3ec.co.uk/media/films/teclogic/b76236ef0ab10e37-d7423c848f04-dark.mp4 129 2026-11-13T00:55:01+00:00 yes no https://www.3ec.co.uk/media/films/teclogic/4b75775544cb5fd1-620361b57d24-dark.webp HVAC - drives, hysteresis, run hours and setpoints HVAC - drives, hysteresis, run hours and setpoints - Drive Set runs a duty and standby pair of pumps or fans. It picks the drive, and fails over on a trip or lost flow. The same Drive Set, with a flow switch on each drive. Double-click the block on the wire sheet - its popup drives it live. Hysteresis turns a numeric input into a clean on/off output. It holds steady between the two thresholds - here set as a band. The same hysteresis, set by upper and lower limits. Run Sync is an hour-run meter - it totals how long its input is true. Like an elapsed-time relay, and it survives restarts. Smart Setpoint turns one occupied setpoint into heat and cool setpoints. It widens the deadband when the space is less occupied. https://www.3ec.co.uk/media/films/teclogic/b52b8f4c8b16307e-620361b57d24-dark.mp4 202 2026-11-09T09:01:32+00:00 yes no https://www.3ec.co.uk/media/films/teclogic/e7c6f78066929655-c5cfd0fa1493-dark.webp Logic - truth tables and input decoders Logic - truth tables and input decoders - Combo Logic - a custom truth table over four boolean inputs.

So start from a schedule - not from a blank folder. BACnet Point Builder - every setting in its own window. Preview first. All 16 rows are checked before anything is written to the station. If a row has a problem, you see it now - not after the points are built. One press, and every point is built. And every tool carries its own guide, so the help is right there in the station. There they are - real points, in the station, ready to use. Modbus Address Shifter. If there are conflicts, the run stops until they're resolved so nothing is moved onto an address that's already taken. Point Rename shows how many points are in scope, then asks you to confirm. Renamed, in one move. Changed your mind? Undo restores them, just as they were. Global Numeric changes a fallback across every matching point, at once. Ten matching points, updated together - not one at a time. This much power needs brakes. Aim a recycle tool at the safe target, and it refuses. Point it at what you want gone, and it shows you the scope first. Confirm, and the folder and its 16 components are gone. The log records who did it. Every module has its own popup with a commissioning override that lets go by itself, so nothing is left overridden by mistake. And every message a module can raise is explained, right there. https://www.3ec.co.uk/media/films/teclogic/06f88e0d5106b4f6-cd977763700a-dark.mp4 176 2026-11-13T00:56:10+00:00 yes no https://www.3ec.co.uk/media/films/teclogic/333e0ae0791ba38a-9d7646b852eb-dark.webp Sequence Stager - staging and duty rotation Sequence Stager - staging and duty rotation - Sequence Stager handles staging and duty rotation across a set of units in one tecLogic module. It's one block on your wire sheet. Double-click it, and you get its own control window live status, and every setting. Set the load from the panel. The module does the rest. One unit is called. It starts, proves that it's running - and then it holds. Nothing else is asked to start until it has proved. Only once it has proved does the next unit come on. Each stage waits for the one before it. Now three are running, and the rest are standing by, in order, ready to be called. Fail a running unit. It drops to the back of the order, and the next healthy unit is called in its place. Once it's healthy again, it waits its turn. The health log records every step - and why. Duty rotate. The order re-ranks by run hours. Each incoming unit proves running before the outgoing one stops. The units hand over one at a time, so the load is carried all the way through the rotation. Rotation done. The wear stays even across the set. It's the same module whether you have 3 units, or 20. You don't need a different block, or different logic, as the plant gets bigger. Same staging, same proving - just more units. Each one is called, proves, and holds, exactly as before. And the full guide is built into the module. https://www.3ec.co.uk/media/films/teclogic/fd80f9d6c45883eb-9d7646b852eb-dark.mp4 208 2026-11-13T00:55:47+00:00 yes no https://www.3ec.co.uk/media/films/teclogic/b191e26d21e35a54-3e9676a25224-dark.webp Drive Set, Hysteresis and Smart Setpoint Drive Set, Hysteresis and Smart Setpoint - Drive Set runs a duty and standby pair, with flow proving and run-on - all in one module. It has its own control window, with live status and every setting in one place. Demand comes on, in Auto, and the duty drive starts. There's no flow yet, so rather than tripping straight away, it holds through a grace period. Here, one shared flow switch proves the pair. Trip the duty drive. The fault latches, and the standby drive takes over. The latch holds until someone resets it. Then it goes back to the preferred duty drive - and the log records who reset it. While the latch holds, the standby drive carries the load, and the fault stays in view. Demand goes off. Run-on keeps the drive going for a while before it stops, rather than cutting it the moment demand drops. That's useful wherever a system needs to run down, or clear, before it stops. Now the second way of working. One flow switch per drive - and it's the same module, set a different way. Each drive now proves on its own switch. Trip it again. The standby takes over, and proves on its own switch. The changeover works just as it did before - only the flow proving has changed. You choose the arrangement that matches the plant on site. Every module carries its own guide. Hysteresis works the same way - two ways of working, in one block. By limits: separate on and off points, so the output never chatters.

Send a Who-Is - and the device answers with an I-Am, giving its instance number. The device appears in the list, and the Who-Is and I-Am frames show in the packet log. Tap the device to open it. Opening it sends Read Property Multiple requests. Each one lands in the log with its reply, so you can see exactly what was asked, and what came back. Its objects fill in, read from the device in batches. Each object shows its name and type - analogue inputs, values, binary points and more. Scroll the list to find the point you're after. Underneath, the packet log keeps running, frame by frame, so nothing happens out of sight. Open a point to see its properties. This is read only - nothing is written to the device.

BMS software engineering and building automation. Energy and automation solutions, for every kind of building and industry. Niagara products - and the BMS engineering services that stand behind them. First, the tec suite: products made for systems integrators. Tools for your stations, for the site, and for everything around the job. tecLogic is one N4 download - forty-three modules and twenty-four graphics widgets. Double-click a block for its own window, with live status and every setting. Graphics are built for the job. Flip a pump, and its lamp answers straight away. tecGfx starts with a portfolio dashboard - the whole estate, at a glance. The buildings page puts every site on an estate map, each one with its live status. Open a floor - level four here - for a live view, with temperatures laid across the plan. Every room, as it is right now. tecTools is thirty tools, in five groups, built for controls engineers. Psychrometrics, for example: enter two conditions, and read off every other property. tecTraining is a set of short online courses, written by working engineers. The lessons carry live diagrams you can try for yourself, not just pictures to read. tecExplorer is our explorer for building automation protocols, on desktop and mobile. And tecScanner captures BMS traffic and analyses it - with findings, and how to fix them. Your client portal keeps everything on your job with 3EC in one place. This is a sample client - a fictional company... https://www.3ec.co.uk/media/films/home/4d3a5a9aebc89092-7fe305f7b61f-dark.mp4 162 2026-11-13T08:13:05+00:00 yes no https://www.3ec.co.uk/media/films/home/a28d795fbb1e9d83-5522ef229736-dark.webp Welcome to 3EC - the home page Welcome to 3EC - the home page - Welcome to 3EC - automating your world. We make Niagara products for integrators and building owners, and we do the BMS engineering behind them. The tec suite sits at the centre of it all - products for integrators, each one a single press away. For your stations, there are modules, graphics, a theme and AI for Niagara. tecLogic puts forty-three modules and twenty-four widgets in one download, and tecGfx is the building platform. tecVader brings a dark theme to Workbench, and tecForge turns a description of operation into a Niagara strategy. On site, you can find it, capture it, and support it remotely. tecExplorer browses the protocols, tecScanner captures the network traffic - and tecSupport, which is planned, will add remote support and a site VPN. Around the job, there are licences, tools, training, and a home for every project: tecStudio, tecTools, tecTraining, and your client portal. The apps go in your pocket too - on phones and tablets, as well as the desktop. Then there's the engineering service: an engineer for your project, with over twenty years of hands-on BMS work. From DDC programming to front-end development - software built for Niagara, protocol integration, automation logic and controller programming, operator graphics, and the panel drawings to go with them. Here are the sectors and systems we've integrated, from commercial buildings to specialist sites. And every page is one press away from the menu.

It's easy on the eyes, all shift long. The nav tree, wire sheets, property sheets, menus and dialogs all share one dark palette - slate navy, with sky blue accents. Status colours keep their meaning. Alarm is still red and normal is still green, and around seven hundred and eighty Niagara icons are recoloured for dark panels. Both browser view styles and the login page follow the same palette, so an engineer in Workbench and an operator in a browser see one consistent look. With tecLogic, one Theme Switch moves Workbench, the station's pages and widgets between dark and light, together. It's a standard Niagara theme module. Install it, pick it beside the built-in themes, and switch back any time. Your logic and graphics are untouched - and it's free with tecLogic and tecGfx. tecStudio is the tool behind the tec suite's licensing. It issues digitally signed licence files, each locked to one machine, and keeps an encrypted register of every licence ever issued. From order to licence: a paid website order becomes a ready-to-send licence. Proof on demand. A built-in conformance check signs every reference case, and confirms the output is byte-for-byte what it should be. Issue a licence from your phone while the customer waits - the same register on a Mac, on Windows, or on an iPhone. Your key stays in your hands. Signing keys are kept encrypted on your own devices, and never leave them.

It's the commissioning and diagnostic tool we built for engineers on BACnet and Modbus sites. Discover the devices on the network, browse every object and property, write values with full priority control, and see every frame that goes over the wire. On BACnet over IP, it handles Who-Is and I-Am, routed networks and foreign-device registration. On Modbus, it reads and writes coils and registers - over TCP, or RTU through a USB adaptor or a gateway. It runs on our own BACnet and Modbus stacks - on Mac, Windows and Linux laptops, and on iPhone, iPad and Android. tecScanner is diagnostics for building networks. It listens to the BMS network, and explains its health in BMS terms, not packets. It captures BACnet and Modbus traffic, decodes it, and maps the devices and networks. It's passive - on MS/TP and RTU trunks it only listens, and never transmits. It checks for duplicate device instances, Who- Is storms, slow replies, lost tokens and Modbus exceptions, and ranks each finding with its evidence, and the fix. The result is a health report your customer can read - a traffic-light summary, a device list, and a network map. tecSupport is planned for the tec suite: remote support for your customers' PCs, and a site VPN that puts your laptop on the building network. It's being designed around the customer staying in control - a one-time session code, a prompt showing who's connecting, chat both wa... https://www.3ec.co.uk/media/films/home/e8ec83647d761115-0de2469617db-dark.mp4 157 2026-11-13T08:13:36+00:00 yes no https://www.3ec.co.uk/media/films/home/ecf7beb0546614b4-ec055921ba05-dark.webp tecTools and tecTraining tecTools and tecTraining - tecTools is a set of calculators and checks for controls engineers - thirty of them, in five groups. Sensor scaling, valve and damper sizing, psychrometrics, MS/TP and IP planning, commissioning sheets, IO schedules, energy savings and payback. Each tool shows its formulas and sources, so you can check the working - and typical values are labelled as assumptions. Save a result to your account and pick it up later on any device, or export a branded PDF report with the inputs, results and sources. They work just as well on a phone at the panel as they do at a desk. Star the ones you use most, and search any tool by name. The tools are free once your account has access. Sign up, ask for access, and we'll switch them on for you. tecTraining is online courses for controls engineers - fourteen courses, with eighty-one lessons between them. They cover BMS fundamentals, sensors and signals, MS/TP and BACnet, commissioning good practice, hydronics and valves, balancing, and commissioning VAV, fan coils, air handling units, and heating and chilled water systems.

Niagara modules, Java and Flutter applications, and the software that ties a site together. Practical, maintainable control software, written for the system it runs on. Protocol integration - bringing every system onto one network: Modbus, BACnet, LON, M-Bus and more. Plant, meters, drives and lighting, mapped and tested, so the front end shows what the plant is really doing. Automation logic - control strategies, written and tested. Control sequences, plant optimisation, and the logic that keeps a building comfortable and efficient. From function block to structured text, each strategy is tested before it goes to site. Panel engineering - control panels, designed and drawn. Single-line diagrams, latching schedules, and the supporting documentation. Every drawing is filed against its project, so the panel builder, the installer and the commissioning engineer all work from the same issue.
