How do you set the timer for the central heating too come on, it is a Valiant Eco Tec plus boiler?
If this is a new property then go and see the agent/sales office. They should give you a basic run over of how to operate the system and they may have the instructions there for safe keeping.If the dont ask them to obtain them for you. The Gas Safety Installation and Use Regulations require the full set of instructions to be left with the homeowner/tenant whatever on completion.
Central heating programmer best ones? siebe Climate control LP722?
Hi I was wondering is there an easy way to get a better central heating programmer that is easy to use. I have a Climate control LP722 also known as a Drayton. Here is a link to it http://www.plumbnation.co.uk/site/drayto... I have the programming instructions but they are a nightmare to follow and the display is so tiny I have to use a magnifying glass to read it. I really hate the many different button sequences to change a simple think like to on or off time. I was thinking of getting their latest one but is it any easier? and would I be better off getting a diffferrent manufacturers hot water and heating programmer? I read ther are obly 4 wires to connect so it should be easy, am I right? Any tips advice will be appreciated. Thanks 10 points best answer
The Knight’s Tour is both a mathematical and logical problem in which a knight visits every square on a chess board of variable size only once and, optionally, returns to the first square after the tour is complete. It is a good way of evaluating algorithm design and efficiency.Programmers with a classical CS background will have encountered this problem, or one like it, in their education.As a predominantly self-taught programmer, attempting to solve the Knight’s Tour gave me a lot of insight into what programmers should think about when designing applications. It tested my ability to think laterally and devise creative solutions to a real-world problem.I started with a brute-force approach: considering every square within two moves and then backtracking out of dead-ends. Then I re-evaluated and refined the logic in my tour program to consider more efficient methods of solving the problem on boards of variable sizes. I tried different strategies like making smaller “virtual” boards from bigger ones, ranking move choices, checking efficiency from different starting points, etc.It was a really fun and cool little experiment.Update: My tiny mind might have expanded just a bit when I implemented Warnsdorff’s Heuristic in my path finding algorithm. At first, it seemed counter-intuitive that searching for positions with the fewest subsequent moves would improve efficiency. That was before I figured out that I had been focusing on “finding” viable paths instead of eliminating unviable ones. Dead-ends are the enemy of my knight’s efficiency, so eliminating them at all costs should be the priority. The following basic algorithm looks for a path with the fewest branches, which statistically eliminates more dead-ends and raises efficiency.Set P to be a random initial position on the boardMark the board at P with the move number “1”Do following for each move number from 2 to the number of squares on the board:let S be the set of positions accessible from P.Set P to be the position in S with minimum accessibilityMark the board at P with the current move numberReturn the marked board — each square will be marked with the move number on which it is visited.Source: Warnsdorff's algorithm for Knight’s tour problem - GeeksforGeeksThe updated version is on my Github repo for anyone that is interested.
I need the instruction manual to set the timer for a Kingshield immersion heater?

It depends. "Industrial robots" are usually defined to mean robotic arms that are used in either manufacturing or biomedical applications. These comprise something like 95% of all robotic arms in use in the world. And the vast, vast majority of these arms are never actually programmed by their end users in any language a computer scientist would recognize. They are almost always used for pick-and-place operations, and they are "programmed" by the user generating specified trajectories for them, often via a teach pendant or a very simple scripting language.Of the remaining few percent of industrial arms that need something more complicated, most are programmed using a dedicated motion control language or ladder logic. Some, but by no means all, industrial robotics manufacturers provide a network interface and a C API to their arms. In my experience, the use of these tools in industrial settings is quite rare.Of course there's a lot of programming "under the hood" that is done by the robot manufacturers that the end user never sees. This is generally considered to be highly proprietary, and I do not know of any industry-wide data, but I'd guess it was a combination of C, VHDL, and (I would guess) some amount of auto-generated code from a controls and signal processing design tool like MATLAB/Simulink or LabView.Note that iRobot is not usually considered a major player in the industrial robotics field - those are KUKA, Fanuc, Motoman, and Mitsubishi Electric. So I am a little confused by your question.If what you really mean is what are *commercially available* robots used in research or hobbyist settings programmed in, then the answer is almost always C at a low level, possibly with higher level language bindings available. Operating systems are all over the board. Windows is still a popular choice; various flavors of Linux are probably second, and RTOSes like vxWorks sometimes also show up, depending on the application.
Central heating not coming on automatically?
I have a Potterton Suprima boiler which, has been working fine until recently. My HW works fine and comes on as programmed, but the CH doesn't come on, regardless of the temperature, unless I turn the temp dial so that it the "reached" light comes on (with not audible click) and then back down to "below" (which does cause a click). A few seconds later the boiler fires up and the heating works. What could be the problem? Do I need to replace the thermostat (Potterton PRT2), check some valves (I'd need some instructions), or get a plumbing engineer out? I had the PCB replaced approx 6 months ago as it was one of the faulty boilers that had been highlighted as faulty on BBC Watchdog. I've not had any problems with the boiler not coming on since then. (As I said, the HW is fine and comes on when required). Any help, comments, advice would be great. Thanks Ged
Coding and programming are terms that can be used interchangeably. There is little difference between a coder, a programmer and a developer. They are just different words to describe effectively the same role. However, their origins are varied.Coder can be regarded as derogatory because it implies that the thinking is being done by others, and the coder is a simple code monkey who doesn’t need to think about what they are doing but just implement the management’s wishes. I believe the term is the oldest of the words - being used to describe as far back as to describe those who worked with mechanical systems such as the Enigma machine during World War II - so Alan Turing was an example of a coder although his work was to decode Germany’s secret code. So traditionally, a coder did not have to use a computer.Programmer is a more modern word, and is used to describe those who enter a series of rules into a system. Although a coder does the same thing, the word entered the mainstream lexicon during the 70’s and 80’s when mainframe systems required people to compose complicated instruction sets - or programs. Consider that a programmer could be someone who programs the central heating to come on. This implies it is at the very least a semi-skilled role in some circles.Developer is a modern word used to indicate the fact that much of the work in software is non-code. Although every role is different, most development roles (particularly at senior levels) will involve gathering requirements, designing solutions, and finally implementing the solution and testing (in tandem as is the case with the Test Driven Development or TDD paradigm).A Web Developer is simply a domain specialisation for a developer.There is also the term Software Engineer which is anachronistic to Developer. It is perhaps reserved for the most complex job roles since it implies a need for a computer science background rather than an autodidact.TL;DR; There’s no official or objective definition. They’re all synonymous and interchangeable. The prefix Web is merely denoting the domain. We could as easily be saying Web Coder or Web Programmer but the standard nomenclature is Web Developer or Web Engineer
Heating control user guide - British Gas UP2?
British Gas UP2 I have a UP2 controller but no manual. I believe this has a 5/2 day program enabling the weekend setting to be different to the weekdays. I can see how to change the heating and hot water settings but not how to change to the weekend program. On the date setting it changes from y:14 to what looks like an n:02 I think this should be m for month, then d:25 being the day of the month. Then it changes to dl5 with the option of on or off, this is the bit I don't understand does anyone know what the dl5 is and it this something to do with the week/weekend settings, I have tried to buy a user guide but just can't find one. I'd like to be able to have different week day settings to weekend settings, I think each day can also have different time settings as I'm at work or out I can't always be at home to monitor what is going on. Any ideas?
To reinforce part of what was said... Your dwelling will lose varying amounts of heat during the course of a day. If you have a very well insulated condo with few outside walls you very well might not need a set back thermostat (programmable). Consumer reports found that in modern construction a high percentage of homes did not benefit from them. After a time of cooling happens in the home the heat must then reheat the space. One way to tell is to note the indoor temp before bed and turn off the furnace. In the morning note the indoor temp. If you started at 68 deg and in the morning it is 64 deg you lost 4 deg overnight. If you might choose 64 as your night time temp on your programmable t-stat, then you would break even. I live in a very cold climate in a drafty old farm house, If I did this test I would wake up to about 58 deg. I have a very odd schedule that changes a lot, so even though I have a set back t-stat, I do not use it. For, I am constantly adjusting it for late nights and out of town trips. If you decide to get a programmable, there are two main types. A 5-2 or a 5-1-1, these give you either one setting for the weekend or individual settings for Sat. and Sun. Also, there is one made by Honeywell that learns your homes particular warm up time. It figures out how long it takes to warm up your house to the set point before you wake instead of just coming on at a set time.
