Many variables can and should influence the decision to run your fan constantly. We recommend that you monitor the temperature and relative humidity throughout the conditioned space in your home. Running the fan on your central HVAC system with the Pureatech System will continuously clean the air passing through the system.

Yes, indeed! This will not harm your humidifier. Promoting good air circulation and continuous filtration in your home has lots of benefits. Most modern furnaces have a low speed setting for continuous operation - refer to your furnace manual. Since the Desert Spring Humidifier is so efficient, you can actually add humidity even when your furnace is not on its heat cycle!

Modern air conditioning systems often use fan delay timers to keep the circulating fan running after the thermostat is satisfied. The reasoning is pretty simple: The evaporator coil is still cold, so it makes sense to get all the cooling you can for the money you're spending in energy. Furnaces have always run for a short time after the call for heating has ended.

Yes, running your furnace with the fan switch set to "ON" keeps the air constantly circulating to make your home more comfortable and filters the air. Combine this with an electrostatic filter to reduce the dust in your home. During the warm months, the circulation will also provide a cooling effect. And this fan position uses very little electricity.

Yes you can. In fact, with some two-story houses, that may be the only practical way to keep the upstairs or bonus room at a reasonable temperature.

Almost all QSC amplifiers have 2-speed or variable speed fans that operate at low speed immediately upon power up. Two-speed fan designs reach the highest speed once a certain temperature is reached. Variable speed fans change rotation speed as amplifier operating temperatures change. The exceptions to this are the USA400 / Series One 1200 which are convection cooled amps.

The fan provided on Progressive Dynamics 9200 and 9100 series converters is an intelligent fan and uses an electronic temperature sensing system that operates the fan only as much as required usually under high current drain applications. This means that the fan typically will not operate at night when the RV owner has turned off most 12- volt lights and appliances and is trying to sleep.

The slower the fan speed is, the hotter the air will be. In general, we recommend a medium to medium high speed.

In most cases I recommend for the fan to be run on Automatic for better humidity control. When the air conditioner cycles off, the inside coil is saturated with water. If the fan continues to run the moisture will be blown back into the home. This decreases the dehumidifying capacity of the air conditioner. There are some homes that need the fan to run on continuous because of rooms that have a faster warm-up time than the rest of the house.

Are the compiler's run-time libraries re-entrant? Can I call library functions from an interrupt? A: Depending on which compiler you're using, yes. If the compiler implements reentrant functions at all, then the library is fully reentrant except for the rand() function, which uses a static variable. The compilers that don't support reentrancy are those with a compiled stack, i.e. 6805, PIC, V8 and 8051 in small and medium models. The 8051 in large model is reentrant.

During the summer, dust particles build up on the heat exchanger. When fall comes, you start your furnace, and the heat exchanger heats up to approximately 200 degrees Fahrenheit. Every time the furnace begins operating, the dust and dirt that built up all summer long begins to burn the dust off, which is the smell that is coming from your furnace.

Generally speaking, yes you should. If, however, you've recently replace one component, you may not need to replace everything. For example, if your furnace was installed within the last 5 - 7 years you probably will be okay just installing a new condenser and coil. Beware of companies who insist on replacing everything, or who claim that you'll void warranties on your condenser if you don't replace your furnace - that's a load of horse hooey.

A common myth is that fan club presidents don't have a life. This couldn't be further from the truth. Fan club presidents run fan clubs in their spare time, like any other kind of hobby. When they're not running their clubs, they have jobs, raise families, write books, and do any number of other things. If anything, fan club presidents have more fulfilling and active lives than most!

This is not generally recommended since the moisture added to the air could condense when it comes in contact with the very cold air conditioning coils. You will likely not need supplemental humidity during the summer months anyway.

If you have a gas furnace with a pilot light you should have the pilot light turned off for the summer. Many people think that leaving the pilot light burning all summer will help cut down on the humidity in the house. This is not true and the big problem is that the extra heat on the heat exchanger causes extra rust.

I'm looking to heat and cool and old theater with no existing system. It is approximately 10,000 sq. ft. and goes from aproximately 20 ft. high in the rear to 40 feet high in the front. It will seat approximately 300 - 400 persons. How many ton system(s) would I need and what kind of system would you suggest? Also could you guesstimate a cost for the unit(s)? THANKS Hello, I have a 5 ton AC unit for my 2100 sf ranch home in Phoenix, Arizona.

There are advantages. One is full-time filtering of the air in your home. Another is that you can maintain a more even temperature throughout your home.

There are ONLY A FEW instances when it is feasible to run more than one project at a time. A fast system, plenty of RAM, and knowing that the work units will complete in the allotted time frame allowed is one example of that. We all know what a surprise it is when others remember your birthday. As part of your online "family" we share in all our team member's grief and joy. We love sharing a new year of life with you.

The SE400 and SE800 are designed to run 24/7, but in most cases, they will not need to run constantly. A good practice is to turn the air cleaner(s) on high speed prior to opening time, to get a head start on air circulation ? this helps reduce the chance of your air cleaning equipment having to play "catch-up." Once patrons start rolling in, you may choose to reduce the air cleaner fan speed if high speed is not necessary.
