![]() That disturbed my father sleeping in a near room. *) the loud “clonk” when it pulled in and sometimes humming from the coil. And even if it would burn out now, it had a 20yr lifetime. So, maybe 2000 or 3000 switching cycles is not much for a relay, but it is sufficient. If there is no cleaning work to do, the pump is only switched one cycle per day by a timer. It makes small sparks at the contacts, but is switching every day in summer since 20yrs. value you get at start up.Ībout 20yr ago I changed the big noisy (*) contactor for the 400V/3 phase 1kW pool pump to a 4 pole relay similar to this one: because of the noise it made. Some datasheets even specify motor load with FLA and LRA (locked rotor amp, the max. I found value’s between 15A and 30A for a typical 10A relay. Posted in Arduino Hacks, Wireless Hacks Tagged ESP8266, mqtt, optoisolator, pool Post navigationĪ relay with its contacts can take some inrush current. ![]() If you are interested in controlling the pool chemistry, we’ve seen that before, too. If you have an older system, you might like to see more of a pool system rebuild. A little configuration into Home Automation rounds out the project. However, the real value to the video is the easy way to interface to the existing controller. does a nice job of explaining some basic concepts like using opto-isolators. The controller makes it available, but it isn’t simple to read, so the project just reads the raw sensor voltage from the existing thermistor and computes the temperature. Another sensor reads the water temperature. Using the Arduino pulse input function makes it easy to sense if the LED is on, off, or blinking. It isn’t going to let you monitor pump currents or anything exotic, but it is a simple place to gain access. The LED reacts differently depending on the pool’s current mode, so connecting there not only gives you control but also allows you to provide some limited status. The remote has a few buttons and LED for status. The electrical connections for these aren’t quite standard, but they are all very similar, so you have a good chance of reproducing this for your setup assuming you have a connection for one of these wired remotes. The project relies on the connection for a wired “spa-side remote” that most modern pool systems support. However, it isn’t as specialized as you might think. Naturally, the instructions are a bit specific to the Pentair system he has. You can see the video description of the project below. For $20, added MQTT control and monitoring to his pool using an ESP8266. In 3 years, the transmitter had burned out ($300 to replace) and he decided he had enough. It wasn’t even WiFi, just a simple RF remote. If your pool isn’t new enough to do that already, you can get a range of add-on accessories. ![]() You can even get them that connect to your home automation system. ![]() Now you have digital controllers and spa jets and heaters. It used to be you had a pump and if you were lucky it had a mechanical timer switch on it. ![]()

The CMA served an initial enforcement order in September 2021 requiring the companies to operate independently, as they did before the purchase.The information available to the CMA indicates that the combined businesses of the CVS and The Vet would provide more than 30% of all veterinary services in each of these five local areas.Following a Phase 1 review, the CMA has found that CVS’s acquisition of The Vet gives rise to a realistic prospect of substantial lessening of competition (SLC) in the local areas around 5 of the 8 practices acquired by CVS, in Bristol, Nottingham, Portsmouth, Southampton and Warrington.CVS refers to CVS Group plc, including its subsidiary CVS (UK) Limited, and The Vet refers to Quality Pet Care Ltd (Quality Pet Care), trading as The Vet.The CMA would then have a further 5 working days to consider whether to accept these instead of referring the case to a Phase 2 investigation.įor more information, visit the CVS / Quality Pet Care merger inquiry page. Should CVS fail to address our concerns we will refer the deal for an in-depth investigation.ĬVS has 5 working days to offer legally-binding proposals to the CMA to address the competition concerns identified. This deal could lead to customers facing more limited treatment choices for their pets or paying over the odds for services in these areas. The CMA has received a number of complaints in recent years about higher prices or lower quality services as a result of too many vets’ practices in the same area being under the control of a single company. Pets are much-loved members of millions of households across the UK and, when veterinary care is needed, it’s important that pet owners have access to a good service at the right price. ![]() This could lead to pet owners facing a worse quality of service, including more limited treatment options, or having to pay higher prices.Ĭolin Raftery, Senior Director of Mergers, at the CMA, said: ![]() While veterinary practices owned by CVS and The Vet currently compete for customers at each of these locations, the CMA is concerned that the combined businesses would not face sufficient competition after the merger. The CMA’s investigation found that the combined businesses would account for a significant proportion of veterinary services in each of these areas. While independent veterinary practices accounted for 89% of the UK industry in 2013, this share had fallen to less than half (45%) by 2021, primarily as a result of independent practices being bought by corporate groups.įollowing its Phase 1 investigation into CVS’s acquisition of The Vet, the CMA has found that the merger raises competition concerns in 5 local areas – Bristol, Nottingham, Portsmouth, Southampton and Warrington. In recent years, the ownership of vets’ practices across the UK has changed, with many practices being acquired by a small number of corporate groups, such as CVS. Recent reports indicate that there are 17 million pet-owning homes across the UK, with consumer expenditure on vets and other services for pets in the UK estimated to be around £4 billion between July 2020 and June 2021. Both firms are providers of veterinary services, with CVS Group owning 467 practices in the UK, while The Vet operates 8 practices across England. The Competition and Markets Authority (CMA) opened its investigation into CVS Group’s purchase of Quality Pet Care, which trades as The Vet, in December last year. ![]() ![]() ![]() A man with a pistol and an attitude, he isn't scared as easily as Victims are. Gunners: Appears only in chapters 1 and 2. ![]() Their purpose is to serve as feeding fodder for zombies and grow the horde in size. Unarmed and easily spooked, they will either run and scream, or stand in place, cowering and paralyzed with fear. Some will simply run and hide, while others will stand their ground and fight with whatever they have on hand. Humans come in all shapes and sizes, and none of them want to be eaten. While the early levels will feature blissful humans that are (relatively) easy prey, as your horde advances, humans will become smarter, deadlier, and hide behind environmental features and traps to kill your precious undead a second time. Unlike zombies, humans are smart and don't appreciate being gnawed upon.Zombies will kill humans and convert them to your cause and feast on their flesh to keep themselves alive. Humans are food and recruits for your cause (of slaughtering the world).Their selfless sacrifice will be forgotten as your undead hordes gnaw on them, but c'est la vie. Their destiny is to become dead, past masters of the zombie-infested world by donating their fresh brains to the zombies. Humans are the living, current masters of the world. These humans remain blissfully unaware of the zombie threat hatching next door. ![]() |
