We usually heat ours to around 85?F. In fact, in the summer, we consider our pool cool if it stays below 90?F (where we live a 115?F is normal).

Just put new batteries in both units but can't get the oudoor temp to show - what have ee done wrong?


Replacement has to be done in a certain order.
  • Remove all batteries
  • Install batteries in outdoor unit. Allow time for unit to initialize and begin transmitting temp.
  • Install batteries in indoor unit. You should see outdoor temperature displayed.

You may find that the outdoor temperature is not transmitted in very cold weather. Right now it is below freezing and my indoor unit is showing - - for outdoor temperature.

Make Your Pool Green!


Energy Efficiency <i>Make Your Pool Green!</i><br /> Pool owners LOVE green pools. Crazy statement if the "green" you're thinking about is unclean, algae-filled water. But when "green" means eco-friendly, a "green" pool is something homeowners should aspire to have in their yards.<br /> Energy Efficiency - Why? Why should I build or upgrade to an energy efficient pool?<br /> <ul> <li><b>1) Reduce Costs:</b> You'll save money. Energy-efficient pool appliances always pay for themselves in reduced electric bills, and then continue to save money for years to come. By choosing pool equipment such a variable speed pump or pool cover, and by establishing good habits like lowering the pool heater when not in use and proper preventative maintenance, costs to a pool owner can be greatly decreased.</li><br /> <li><b>2) Cuts down on energy waste and saves water:</b> Almost all of a pool's heat loss-about 95 percent-occurs at the surface, mostly through evaporation to the air and radiation to the sky. By using a pool cover to prevent heat and water loss, the amount of chemical water treatment will also be reduced. A multispeed or energy efficient pool pump can also significantly reduce the power consumption of a swimming pool by over 65%.</li><br /> <li><b>3) Tax incentives and rebates:</b> Did you know that some states offer tax incentives and rebates for homeowners that purchase energy efficient pool appliances? Check to see what incentives or rebates are available in your state..</li><br /></ul> Energy Efficiency - How? With a combination of pool products and good preventative maintenance habits, you can improve the heating and energy efficiency of your swimming pool.<br /> <ul> <li><i>Pump Efficiency-</i> You can save energy and maintain a comfortable swimming pool temperature by using a smaller, higher efficiency pump and by operating it less. On average, an energy efficient pump will use 30-45% less energy than that of a standard pump. The difference over a season can be immense. Pumps now come in two-speed, four-speed, and variable-speed models, so you can turn the speed down for regular daily use saving a lot of energy, and use higher settings for more thorough, less frequent cleanings. New energy-efficient pumps also move the water more efficiently for further savings. Since pumps circulate the water to keep it clean, the better they work, the less a filter has to work. <ul> <li>The <a href="http://www.pentairpool.com/pool-pro/products/pumps-inground-intelliflo-vs-3050-vs-svrs-variable-speed-pumps-76.htm">Pentair IntelliFlo&reg;</a> High Performance Pump is the world's smartest swimming pool pump. Its onboard computer and intelligent software automatically calculate and program the minimum flow requirements for every pool task - filtering, heating, cleaning, spa jets, water features and more - to optimize performance and minimize energy use. As functions/tasks change, IntelliFlo&reg; self-adjusts to maintain optimal flow rates for further energy savings.</li><br /> <li>With the <a href="http://www.haywardcanada.com/inground/products/pumps/EcoStar.cfm">Hayward EcoStar</a> family of pumps, money flows back into your pocket. EcoStar is the industry's most energy efficient variable speed pump, thanks to a super-efficient permanent magnet, totally enclosed fan cooled (TEFC) motor and industry leading hydraulic design. Tests prove that EcoStar can save you up to 90% on energy costs compared to ordinary single speed pumps. EcoStar matches pump flow to a pool's needs, versus running at full power 100% of the time. It's fully programmable with a self-contained 24-hour clock and up to 8 custom speed and timer functions that allow EcoStar to manage flow throughout the day. Whether used in new construction or aftermarket applications, EcoStar is the perfect choice.</li><br /> <li>Pentair has a calculator that you can use to <a href="http://www.pentairpool.com/pool-owner/resources/calculators/pool-pump-calc/index.html">calculate your energy savings</a> using an energy efficient pool pump.</li><br /></ul></li> <li><i>Pool Covers-</i> A good pool cover will save energy and water. It can keep the water in your pool an average of 10 degrees warmer, which can cut summertime pool heating costs by up to 90 percent. A cover reduces water and chemical evaporation by up to 70 percent, saving nearly a thousand gallons of water per month. A cover also helps keep your pool clean, which means you'll have to run your filter pump less often, saving even more energy.</li><br /> <li><i>Water temperature efficiency-</i> In addition to a pool cover, there are other ways to help keep the cost of heating your pool to a minimum while you still enjoy a comfortable water temperature. Make use of solar energy by locating your pool in the sunniest part of your yard. If possible, screen it from the cooling, prevailing wind with existing structures such as the house or garage, or add a solidly built fence as a windbreak. The water temperature you desire for your swimming pool not only affects the size of the pool's heater, but also your heating costs if use a gas or heat pump pool heater. Heating your pool with solar energy is by far the most energy-efficient method. If you buy a gas or electric heater, check the yellow-and-black Energy Guide label on the appliance. It shows relative energy-efficiency according to tests by the US Federal Trade Commission (FTC). Pool water temperatures typically range from 78&ordm;F to 82&ordm;F. The energy consumption for each degree rise in temperature will cost 10%-30% more in energy costs, depending on your location. In warmer climates, this percentage is higher because of the relatively low cost of heating a pool at 78&ordm;F.</li><br /> <li><i>Timers-</i> Buy automatic timers for both your pool heater and pump. This will allow you to run them in several short cycles during the day, which is more effective than running them once continuously for several hours a day.</li><br /> <li><i>Preventative Maintenance-</i> Maintain efficient daily operations. Turn down the pool heater when the pool is not in use and maintain appropriate water temperatures when in use (78&deg;-80&deg; for active swimming, 82&deg;-84&deg; for recreational use). Raising the water temperature just 1&deg;F can costs an additional 10 - 30%, depending on your location. Keep a thermometer in the pool to help determine the temperature that is best for your pool and mark the "comfort settings" on the thermostat dial to avoid accidental overheating. Backwash the pool filter only as much as necessary to avoid wasting water and energy and be sure to keep drain systems clear to allow the free flow of water. By far, the most energy efficient lights you can get for the pool are LED or solar powered.</li><br /></ul> Energy Efficiency - Not just for pools! It is also possible to make your spa energy efficient. Portable spas are more energy efficient than in-the-ground spas because they are better insulated and usually have covers. If you have a typical portable spa, your heater will heat water 10 degrees in about 8 hours. If you use your spa once a week, lowering the temperature 3 degrees when not in use will save you approximately 5-10% of your spa heating costs; if you use the spa less often, your savings could be even greater. Don't run the jets unless you are using your spa. The mixture of water and air is great for relaxing the muscles, but it cools the water quickly. Spa covers are important. Be sure to leave the cover on until you are ready to use your spa and replace when you're finished. Remember that the heat that escapes is the heat you must pay to replace.

Pool heater won't heat water


How big a pool? You normally will not notice a temperature rise immediately. On average, swimming pools will see a one degree rise in temperature every 45 - 90 minutes.

The extra benefit of a Modulating Boiler


You're looking to install a new hot water boiler or replace your existing boiler. You come across something called a "modulating" boiler. You wonder what on earth that means. I will attempt to explain some of the features of a modulating boiler.

How nice would it be if you could have your boiler make just enough heat to keep your house warm and nothing more? Your thermostat tells your boiler that you need heat in the house. The boiler starts up and heats the water that runs through the pipes to heat your house. The water does not heat up to temperatures that are more than just warm. But you notice that the temperature in your house is staying right where you want it to be.
This boiler is no ordinary boiler. It knows what the temperature is outside and varies your water temperature to make just the heat needed to keep you comfortable. The modulating boiler also runs much more then a normal boiler would but you can see by your gas bill that you are getting great efficiency from this thing.

The feature that makes this wonder so great is that it has the ability to vary the fire that heats the water up and down so that the water temperature stays precisely where the computer brain in the boiler wants it to be. This temperature is figured by measuring the outdoor temperature and changing the water temperature based on that. The colder the weather is outside, the hotter the water is going through your system.

With a system like this you will notice that your heat will run longer and still not cost anymore money. This makes you more comfortable. The modulating boiler will give you just enough heat to keep you warm without wasting much of the heat that a normal boiler would. This type of furnace will give you the most efficient heating possible on any given day.

Before buying a new heating system or replacing your old hot water boiler make sure that you check into a system that will modulate the fire and also vary your heating water temperatures according to the outdoor temperatures. This will save you money and give you a very comfortable heating system.

Freezer turns of in cold weather


Many residential refrigerator / freezers are designed to work at temperature considerably above above freezing. Most modern refrigerator / freezer have a single electric thermostat - located in the fresh food compartment. This lone thermostat will control the compressor to keep the fridge (fresh food) section at the desired temperature (usually between 34 - 38 degrees F). The freezer will get colder regardless of how cold it is already whenever the fridge thermostat turns the compressor on.

Now that you see how the thermostat works, let's look at what happens when the fridge is placed in an unheated space - like a garage. In winter time, the temperature can drop considerably below 38 degrees. If the outdoor temperature remains cold enough, for long enough - it will affect the thermostat in the fridge. The temperature inside the fridge could drop below 38 degrees, preventing the thermostat from telling the compressor to turn on. Meanwhile, the temperature in the freezer compartment slowly rises from the normal -10 to 0 F degrees. It will continue to rise until it is the same temperature as the fresh food compartment or until the thermostat in the fresh food compartment tells the compressor to turn on again. This means the freezer contents will thaw.

If the temperature in the garage is even in the 40 to 50 degree range, the loss of cold in the fridge may not happen often enough to keep the compressor coming on often enough to keep some freezer items frozen solid - such as ice cream. Remember, water freezes at 32 degrees F, other products may require lower temperatures to remain frozen, and could thaw at 28 or other temperature.

Good luck!

Showing a LP on display. What are the possible problems?


Here is the reason for that problem per the manufaturers web-site

http://www.haywardnet.com/products/Manuals/pdfs/Manual122.pdf

The low-pressure switch senses the refrigerant pressure in the sealed refrigeration system to

protect against certain conditions that could be detrimental to compressor life. The switch shuts

the unit down in the event of loss of refrigerant, fan motor failure, evaporator freeze-up and

airflow blockage. The switch automatically resets when the pressure rises to normal operating

pressures. The display will show "LP" if this switch is tripped.

Evaporator Freezing

The low-pressure switch will shut the heat pump down when the evaporator starts to freeze.

When the unit starts to freeze the low-pressure switch will be tripped, causing the display to read
"LP" This will prevent the evaporator from becoming damaged or deformed.

If the air outside the heat pump is not warm enough to produce heat, the system will shut down.

The actual point at which your unit will shut down due to low temperature varies depending on

which model you purchased, current weather conditions, and the amount of sunlight reaching the

heat pump. The shutdown can occur anywhere within a wide range of temperatures, usually 45°F-

55°F. This is not a "fixed" range. We stress that climate conditions, sunlight, and various models

respond quite differently to low ambient temperature. A shutdown occurs because low

temperatures will activate the systems low-pressure safeguard switch (digital thermostats will

display a code "LP".) The unit will start up again when the temperature has raised enough to reset

this switch. Note: Low ambient temperature does not necessarily affect the Chiller models
or the cooling cycle of the heat/cool units.

Over exposure in cold weather


I suggest that you contact Tokina directly to find out what range of temperatures your lens is designed to work across.

Your expression "cold weather" is an imprecise term; where I am in the UK means at worst down to a few degrees below freezing and usually a bit above, but when I'm in Moscow they don't consider it to be cold until the temperature drops to around minus twenty-five Celsius.

Depending on where you are, your lens may simply be unable to cope with what you describe as cold weather but you won't know until you have the specifications from Tokina. If it turns out that your lens is not performing as intended, then the manufacturer will be able to suggest remedies to you.

Sorry I cannot be more specific but Tokina do not appear to have published the range of operating temperatures in the public domain.

I have a vitodens 100-w combi boiler and tried to turn the heating on just to give it a working as was advised. However, I have no heat coming to my radiators. The boilers seems to be working as my hot...


Here's the deal: If your Vitodens 100 has outdoor temperature sensing capability, either built in or via external aftermarket control such as Tekmar or other, and the temperature outside is above warm weather shut down (WWSD), then the boiler will not operate for space heating, but will operate to make Domestic Hot Water (DHW) only. Generally speaking WWSD is facoty set at 20*C, since this is normal room temperature so the boiler will not need to operate at temperatures above this number as it is warm enough outdoors to heat the house to comfortable levels.
If your Vitodens 100 does not have outdoor temperature sensing capability then you should check to see if your room thermostats are operational and calling for heat since the boiler is only responding to this on-off control based on room temperature. (turn up your room thermostats)
In both cases you need to make sure that your heating system's distribution pump and zone valves are operating correctly.
In any case you should be calling a heating contractor if you suspect that there is a problem with your boiler and/or heating system.
Good luck.
