Release when you see the desiredThis eliminates the problem of time loss that occurs with a traditional mechanical time clock. Your pool requires less chorination when the water is cold, so TightWatt pool timers work synchronistically with the needs of your salt-water pool. TightWatt pool timers take advantage of the yearly changes in temperature, and run your pump efficiently year-round (like a digital thermostat does for heating and cooling). This also reduces pool maintenance time and saves wear-and-tear on components. Tap the button again when theCan I view it online? The benefit of X10 is that you can add simple communication functions to your house at a very low cost. Switches, lights, appliances, etc.Geeks, however, can also use X10 to run their pool and other home gadgets through internet, phone connections, or pretty much anything else. In short, yes.http://ninethreefox.com/?q=node/10584 Press any button, andAll other settings are stored in FLASH,Check with your utility to see if they offer a rebate for TightWatt2 controllers. The year-round control that the TightWatt2 offers is the most efficient way to run a 2-speed pump. The TightWatt2 year-round run schedule will also help to extend the life of your cathode, saving money on costly repairs. The low-speed moves the water more slowly, but gives you much more gallons filtered per dollar. This provides superior filtration and dramatically reduces the energy costs of your pool. Next, select the number of hours you want to run for high, low, and auxiliary. If no buttons are pressed for 7 seconds, the manual cycle will start automatically. In most cases, the TightWatt2 can replace two mechanical timers. The next automaticAfter that, set the following cycle: 'Hi 1 Lo 0 Ax 0', and the backflush will start.It should be noted that the fireman's switch uses the Auxiliary relay to function, so the Auxiliary relay cannot control a booster pump when used in this mode.

Ed Rempalski 5.http://flexphysicaltherapy.com/images/bretscher-solutions-manual.pdf0 out of 5 stars As others noted the actual SPDT load switch on the new unit has the Normally Open and Normally Closed contacts reversed as compared to the original switch. Funny thing is that the printed diagram's on both units is the same and I'd say that the old unit was actually wrong. In any case it was a 5min swap to fix my panel and sort the connectors. The original unit lasted over 15years so hopefully this one will go the same distance.This photo from the supplier does not depict that feature. The override feature controls; on, auto, and off modes. The clock operates in the auto mode. I took a chance on it being the item I needed and was correct due to the correct description. All Intermatic FM clocks by 1000 bulbs have the identical picture even though they are different. This clock is also known as a Grasslin brand clock. Intermatic acquired them a while ago but the clocks still have the Grasslin brand name on the face. This clock is used to run my pool pump. I could not find this clock at my local pool supply house. I happened to notice that the Amazon supplier used the same photo on each picture. After much resurch I found that Grasslin was acquired by IM so I went to the IM website to gain a part number match. Other than the minor photo mix up I am extremely satisfied with the service I receivedWorks perfectly and only took 5 minutes to install My old one was losing time it would turn the generator on but not off.so of course I had to take it completely apart.probably some stripped gears but I'll never know now since they all fell out and no way to tell how they go back in.:-)When I use the electronic timer it is 1) difficult to set up with the current time and the operating intervals; 2) even though it has a battery backup, it loses the current time setting when a power outage occurs; 3) the button controls are unresponsive at times when trying to set up the timer; 4) various other problems with the operation of the device.https://www.a2zmedical.com.au/wp-content/plugins/formcraft/file-upload/server/content/files/1628669a80cf54---c500-service-manual.pdf Although I have not installed the intermatic non-electronic timer yet, I can see that the interval setting are very simple as well as the current time setting. This timer should simplify and greatly improve my ability to control the swimming pool filter that I will use it for. One strike against electronic gadgetry.Old on kept flipping from auto to on - ran often overnight. 3 screws, swapped each connection old to new. Set timer. Worked like a charm.Apparently Intermatic acquired Grasslin at some point in time. The new unit is ALMOST identical to the original except for the layout of the 5 terminals. They are not in the same sequence. Check the instructions which come with this mechanism as you transfer connectors. I checked with my customer and he reports everything is working as it should and he's had no problems to date.Very easy to install. Direct replacement.It was easy to remove, replace, and setup. It uses spade lugs on the back, so the electrical is a cinch. This model has a bypass switch which my previous model did not. This allows you to turn on the pump manually without changing the timer. I would highly recommend.In order to navigate out of this carousel please use your heading shortcut key to navigate to the next or previous heading. When it comes to pool timers, this is 100 true, as long as you know how to set a swimming pool timer. I kid you not! That usually takes about 8 hours, sometimes up to 12 hours. Save energy by installing a pool timer is one way to cut the pool costs. You won’t have to do it manually. We’re all forgetful at times but pool timers aren’t. Pool water circulation will help remove all unwanted pool contaminants, including algae and bacteria. The pump is also essential in proper distribution of all the chemicals in your pool water. Also, single-speed, two-speed and variable-speed pump may require different timers. Consider the voltage, too. Most timers have selectable-voltage switch to enable switching from 120-Volt to 240-Volt.www.bascoy.com/userfiles/files/carl-lewis-awd15-manual.pdf They are grounded for protection and most have a lockable casing for even more high-voltage safety. If it’s going to be outdoors and exposed to bad weather, make sure your timer has a weather-proof casing. This will also help with humid or dusty environments, such as your basement or the garage. They are easy to control and easy to set up, too. If you have a different timer, chances are it will be as simple to set as this particular unit. It’s a robust and long-lasting timer, but, it won’t be of any help unless you set it to control your pool pump properly. The silver “arrow pointer” needs to be aligned with the correct time. In this photo, we can see that it is 12 pm. Loosen the small set screw and set the time that you want your pump to turn ON or OFF. As simple as that! Set the “Off” clip to the time you want the timer to turn off. Tighten its screw again. They cannot be used in place of each other. This means that you can’t substitute a lost “on” trip lever with the “off” lever. If you take a look at the back of the trip levers, you will see that they are configured differently for that purpose. In case it doesn’t, press reset using a paper clip. If the display is still blank, check the power supply. If you have selected the 12-hour format, make sure that PM appears on the screen when an afternoon time is displayed. To switch mode, press the MODE button for 3 seconds. Briefly press the MODE button to activate or deactivate the load. (If you have connected a remote switch to the timer for a 3-way installation, the switch can also be used to activate or deactivate the load.) The mode indicator (MAN) and the state (ON or OFF) are displayed. The mode indicator (AUTO), the state (ON or OFF) and the current program number are displayed. The new state indicator will flash to show that this state is temporary. The override remains in effect until you press the MODE button (or use the remote switch) or until the beginning of the next program.https://verkoop-je-wagen.be/wp-content/plugins/formcraft/file-upload/server/content/files/1628669b67126c---C500-manual.pdf NOTE: If you want to apply the same program to each day of the week, press DAY until all the days are displayed. (This still counts as 1 program, not 7.) If you have selected the 12-hour format, ensure that PM appears on the screen when an afternoon time is displayed. NOTE: If you have used only one program to set the ON time for all 7 days, the OFF time of that program will automatically apply to all 7 days. Clearing a Program Press the PGM button until the desired program is selected. If you have serious doubts about installation and wiring, call a professional. So it should be easy enough to have your pool timer up and running in no time! I love helping out other people with real, honest advice and spending time with my family.

By setting your pool pump timer to operate during non-peak hours when there is less electrical demand, you might save a considerable amount of money. Pool timer controls can be as simple as a clock, or you can use an elaborate electronic device that you can control from your smartphone. No matter the style or brand, programming is similar for all pool pump timers. Clock Style Timer Grasp the outer edge of the clock dial and pull the dial forward as far as it will go. Set the clock dial to the appropriate time by turning it clockwise or counterclockwise. Use the permanently attached metal band as the time indicator. Loosen the “On” and “Off” clips with a screwdriver. Move the “On” clip to the desired start time on the clock dial and tighten the screw.https://grupomarsamo.com/wp-content/plugins/formcraft/file-upload/server/content/files/1628669b9dd04b---c508a-manual.pdf Set the “Off” clip to the time you want the timer to turn off. Tighten its screw again. Electronic Timer Pull open the front flap of the timer box to expose the controls. Set the time and date. Press the “Mode” button until you see “Set Up” on the screen. Some models have one more step to set daylight savings time. Press the “Mode” button again until you get a timer screen. Press “Mode” once again. This time you should see a second timer screen. Set this for the time you want the pool pump timer to shut off. Hit the “Mode” button one more time to save your settings and activate the timer. Check that the timer operates during the time you specified. Reprogram the unit, if necessary. Tip Set the cleaner pump, if your pool has one, to operate within the hours of the pool pump’s operation. Set the cleaner pump’s timer in the same way you set the pool’s pump timer. The swimming pool pump should operate 8 to 10 hours a day in the summertime to turn the water. If you don’t winterize the pool, the water should circulate 4 to 6 hours a day. Set your timer to reflect the appropriate season. Start with the longest recommended pumping time recommended by the pool’s manufacturer. Shorten the pump’s operating time by 30-minute increments until you find a time that leaves the water clean on a daily basis. Operating the pump a shorter amount of time saves wear and tear on the pump equipment. Alternatively, use a timer that allows you to operate the pump multiple times during the day for shorter periods. An electronic timer sets much the same way as a digital clock. Each brand is slightly different, but the on-screen prompts help you follow the steps for setting up the timer. Things Needed Screwdriver Tips Set the cleaner pump, if your pool has one, to operate within the hours of the pool pump’s operation.

Once you've enabled Javascript, please refresh this page.It is fairly simply but it requires an extra wire to be able to switch between a low speed circuit and the high speed circuit. If you are going to wire your own pool pump, you must first know what voltage is coming to your pump from the house circuit breaker. Also you must ensure that the electrical supply agrees with the motor's voltage, phase, and cycle and that all electrical wiring conforms to local codes and NEC regulations. If you are unsure of this voltage or are unfamiliar with electrical codes and regulations, have a professional electrician wire your pump for you or at least check your work. Failure to wire the pump correctly can cause electrical shock or can damage your pump motor and void your warranty.Four wires will come from the timer to these terminals as shown. The wires are color coded to show how each connects to the timer. This motor is designed to run only on 230V. If your motor is designed for 120V or 230V, make sure it is configured for the supply voltage (from the house circuit board) that you will be using.Circuit 3 is extra and can be used to control any other pool function like controlling your pool lights. The Timer has 8 terminals as shown at the bottom of this picture. Terminals 1 and 2 are connected to the supply lines from the circuit breaker. For 230V either line can be placed on either terminal. A volt meter placed across 1 and 2 after wiring will read around 230V for 230V supply. Terminals 3 and 4 provide the high speed circuit. Terminals 5 and 6 are allocated to the Low speed circuit.The Timer connections are at the top; the motor connections at the bottom. Supply Power is shown coming in from the top and connecting to terminals 1 and 2. Either wire can go to either terminal. Finally connect the ground wire from the motor to the timer ground.See your user's manual for programming instructions.Make sure the switch is set to the 240V position for this configuration. This assumes that the supply voltage and motor configuration are 240V. If your motor is configured for 120V, your supply voltage must be 120V and this Timer power switch has to be set for 120V. If the voltage switch is in the wrong position, the Fuse (next to the switch) will blow and you may cause damage to the circuit board voiding the manufactures warranty.Mode 1, for example, would be used to control any three independent circuits. A 2-speed motor will use mode 2. To set the Timer mode, use a small tool to press and hold the mode button for 5 seconds. Push the Up or Down arrow keys until Mode 2 is displayed.Glad we could help.

By turning the pool's pumps on and off at prescribed times, you can run the pumps when you need to and shut them off during the hours the pool isn't in use. Some newer electronic timers not only operate the pumps, but they may also control the heaters and the lighting system for the swimming pool. Generally you can troubleshoot pool timer problems before you call a service technician. For automatic timers, check to see if the LCD panel shows that the timer is set. For dial timers, look at the timer and note the position of the dial. Let a few hours pass and return to check the timer. If the dial is in the same position, the swimming pool timer either isn't working properly or it's not getting electricity. You should also see the gears behind the dial timer working if there is electrical power to the timer. You can find this switch under the pool timer dial. Otherwise the swimming pool timer may operate at odd hours. Gently pull out the time indicator bar. Align the bar with the current time and push it back into place. Slide it around the pool timer dial to the correct start time and re-tighten it. As the hours of swimming pool use increase during the peak swimming season, you may need to adjust these pins periodically. If the dial hand gets bent, it may snag on the pins keeping the pool timer from operating properly. You can easily straighten the dial hand.

Houston attended St. Edward's University, graduating with a Bachelor of Arts in photocommunications (photography and digital imaging). The pool timer is connected to a grounded power source and wired to a pool pump. While electrical signals are used to command the pool pump, the pool timer is mostly mechanical. Because a pool timer is an electrical timer with mechanical aspects, the clock dial portion of the timer pulls out to set the time.The darker-colored tripper can be placed against the desired turn-off time and tightened down with a screwdriver.An electrical signal is sent from the timer to the pump and the pump activates.You can pull the clock dial out and twist it until the correct time correlates with the time marker.

Benefits of Having a Pool Timer 6 Considerations For Buying a Pool Timer Best Pool Timer FAQs Conclusion Pool timers are accessories that not every pool owner starts out buying. Some people might think it’s just as easy to set a timer on their phone and go out and turn their pumps on. And well, you can absolutely do that if you want to save a few bucks upfront, but there are a couple of things to consider. For one thing, pool timers are usually very inexpensive. And most of them are super easy to install so labor costs are zero. But secondly, they will save you so much time and money in the long run. Do you really want to sit around all day, waiting for your timer to go off so you know when to go outside and turn your pump on. And what happens when you forget or go out of town. That might not sound like a big deal until you come home from vacation to a murky pool full of algae. Then you’ll be spending more money on chemicals and more time cleaning it up than you ever thought you’d have to. For the small amount of money you’ll spend, this little gadget can be the best thing you ever buy. You can even manage as many as 12 appliances with it in a 24-hour period. In other words, you can set this handy little gadget up to control not only your pool pump, but also your outdoor lighting and anything else you want on a timer. This product is a basic, dependable timer that can handle all your needs, and as a bonus, it’s easy to install. It’s specifically made to stand up to any type of weather. It’s also super easy to use and you don’t have to be technologically inclined to do it. You simply stick a green pin in the machine at the time you want it to start and a red pin where you want it to stop. This means that no matter how bad the weather gets, this little baby will keep on going. This timer is programmable in 15 minute intervals. It can be used with things like Christmas lights, pool pumps, water fountains, and other outdoor decor with complete accuracy and dependability. It’s also built with a. HP capacity so that it can control your most powerful devices, like larger pool pumps, outdoor heaters, and more. Setting this timer is very simple.

This timer is designed to work with all types of electrical power sources, so it’s recommended that it be installed by a professional. What is a pool timer. A pool timer is a special device that you can connect appliances to in order to turn themselves on and off at certain times. Why does that matter, you ask. The simplest answer is that it saves you money, especially when it comes to running your pool’s filtration system. It’s possibly the biggest energy-sucker in your home. Energy costs range from state to state and town to town. And the cost to run one depends on factors like size and number of hours operated. But if you let it run longer than it’s supposed to very often, your pool will be cleaner, but your energy bill will be sky-high. That’s where a pool timer comes in. I mean who wants to try to remember when to turn it on and off and go outside and mess with that several times a day. And what if you forget. Using a pool timer ensures that your pump is running for the optimum periods of time to keep your pool water safe and clean. And you can always adjust it from month to month to account for different factors like increased usage or climate changes. A pool pump is usually plugged into its own outlet that supplies its power source. But if you use a timer, you’ll plug the pump into that and then the timer into the outlet. What the timer then does is mediate the connection so that it disrupts it when it’s set to go off and reconnects when it’s time to turn on. Think of it kind of like a spray nozzle you connect to the end of your water hose. It only allows the water to flow out of it when you squeeze the nozzle. Most pool timers use little pins that you place in the time slots you want the timer to turn off and on.
