HOW COMFORT GETS DONE!

The FanHandler and ecMModulator control lines are designed to eliminate comfort complaints that are common to most heating and air conditioning systems. They are designed so that just about every residential and small commercial heating/cooling system can be vastly improved to give unmatched comfort and efficiency. They can convert any furnace, air conditioner, or heat pump to eliminate the old fashioned off/on/up/down cold floor/hot ceiling/ clang/bang/thermal shock from room to room/level to level systems into modern comfort machines that deliver smooth, quiet, draft-free, comfort from room to room, floor to ceiling, level to level and moment to moment. Efficiency and Indoor Air Quality are vastly improved.

If you are a homeowner experiencing drafts, high-speed air noises, uneven temperatures from one part of your home to the other....

If you have a Lexus in the driveway and electric heaters in the kids rooms....

If your definition of "roughing it" is setting the electric blanket to medium....

If you have to turn up the volume on the TV every time your heat or air conditioning system comes on....

....Then this web site will be of vital interest to you.


If you are an HVAC and/or indoor air quality contractor and want to knock the socks off your competition; then you'll want to study this site carefully.


You are no longer stuck with equipment that doesn't allow you to use your training and talent to provide a truly comfortable, daft free, noise free and efficient indoor environment for your customers. AND you can even eliminate the inefficient zone bypass dampers!!

What is FanHandler Inc?

FanHandler Incorporated is an electronics and mechanical engineering company that specializes in developing
and marketing advanced Variable Speed control systems for the HVAC industry. The FanHandler line of temperature
responsive blower and pump speed controls was started in 1953 with mechanical speed controls for belt driven blowers.
In 1961 we introduced our first electronic Variable Speed controls for psc and shaded pole motors for direct drive blowers.
There are many models and voltages of FanHandler controls.
FanHandler Inc. is devoted to home comfort, Indoor Air Quality and efficiency. Before you go further, make a list
of what you would change, to make your home more comfortable. Then find the solution in this website. Some
surveys show that about 74% of homeowners have one or more complaint about their HVAC system. We say:
THEY DON’T HAVE TO PUT UP WITH IT!
 
Our latest, and wildly successful, control is the ecMModulator which does everything for an ecm motor that the
entire FanHandler line offers, plus a lot more. The ecMModulator makes it possible to replace the psc motor on
any equipment and have one control that is pre-programmed to fit any type of equipment. No guesswork, no dip
switches, no timing questions, no high end tech requirements. And, it can even eliminate the need for the inefficient
bypass damper on zoned systems.

The ecMM odulator’s advanced electronic circuitry and highly advanced programming, combines old fashioned common sense with many years of experience and the high efficiency and silent operation of an ECM motor. The result is a product that eliminates the major complaints associated with residential heating and air conditioning systems. The ecMModulator can be installed on a very wide variety of HVAC systems, new or old, any make or model furnace, air conditioner or heat pump, any fuel, any time of year. The installation is quick, clean and you probably will not notice slight interuption of heat or cooling during the install.
 
 
 
 
 
 
 
UNMATCHED COMFORT, SILENCE, EFFICIENCY, IAQ, & VERSATILITY
 
  • Smoothly and seamlessly modulates the blower for both heating and cooling in response to delivered air temperatures.
     
  • The Whisperer 4Z has an on board pressure transducer to limit the duct pressure in zoned systems. Eliminates the
    need for inefficient dump zones and bypass dampers! Holds within 0.02” wc. Pressure setting and is easily field
    adjustable. No zone system is complete without it.
     
  • Jumper allows for furnace or heat pump operation, or both if you want to switch the active mode for hybrid systems.
     
  • Accepts a dry contact closure to allow adjustment of AC coil and output temperature from a humidistat signal.
    Easily drops humidity 10% and more in most humid climate installations. PLUS, in dry climates it doesn’t dehumidify
    any more than any other form of AC. If it doesn’t see a humidity load, it doesn’t go after it!
     
  • Minimum speed (IAQ) adjustment allows constant fan in even the most humid climates. Keeps all IAQ
    products functioning at peak efficiency. Can be set as low as 200 silent and draft free rpm for those periods
    when the blower would normally be off.
  • Has a 0 to 10 vdc output signal which allows control of frequency drives to modulate single phase or
    three phase multiple horsepower pumps and large belt driven fans with the same results and features as
    residential equipment.
  • Digitally computer based programmed, so can be re-programmed for special applications.
 
 
ECM motors were designed to MODULATE. Not timed speed steps! (Time is for catching the bus) The ecMModulator provides 100% smooth true, seamless Variable Speed modulation for existing ECM systems and for converting PSC equipment to ECM. Any existing system can be modernized with one “plug & play” unit that fits all applications.
PLUG AND PLAY INSTALLTION
 
 
 
ECMandSensor

 
The next time you notice that cold room, cold floor, hot upstairs , cold downstairs, up and down temperatures, blower banging on and off and waking you up at night, having to turn up the volume on the TV when the blower comes on, REMEMBER you don’t have to put up with it. The only thing wrong is you don’t have an  ecMModulator or FanHandler control.
 
 
The next time you notice that cold draft, REMEMBER you don’t have to put up with it. The ecMModulator will solve the problem. Comfort isn’t noticed, It’s just there. All the time throughout your home, floor to ceiling and room to room.
 
 
 
 
HOW IT WORKS
 
The ecMModulator
communicates with the temperature sensor located in delivered air. This information is
converted into an electronic signal going to the ecm motor. The ecm motor turns the blower at the proper
rpm for every delivered air temperature FOR BOTH HEATING AND COOLING.
During heating, it can’t blow a cold draft because, when the air entering the home isn’t very warm, the speed of
that air is slow. As the temperature of the entering air increases, the speed increases. On most winter days, the
blower may never reachfull speed before the thermostat is satisfied. Once the burner shuts off, the blower
glides back down along the temperature path untill the blower is running very slow and continous (optional) until
the next heat cycle. Heat pump systems average about 15° higher for delivered air temperature. This keeps the
delivered air cozy and warm.
 
 
 AIR CONDITIONING HVAC FACTS
  • HVAC systems are sized to meet the hottest and the coldest weather conditons you will encounter in a
    year’s time. This is called “design conditions”.
  • In some years, design condtions will happen maybe a couple of days in a year or maybe not at all.
  • At any time you are not experiencing the hot and muggy air conditoning design conditions, your air
    conditioner is off a good portion of the time. During these off periods, humidity builds up in your home.
  • Because the high speed blower is innefficient at removing humidity, you end up
    with that hot and muggy feeling. So, you set the thermostat down and you end up
    with the cool and clammy (smelly sock) situation.
  • Because of the programming of the ecMModulator, it forces your air conditioner to
    wring the moisture out of the air. You remain comfortable and cool
 HEATING HVAC FACTS
  • At any time you are not experiencing heating design conditions, your HVAC system
    is too large.
  • The blower starts and blows the same way that it would if it were the coldest day
    of the year.
  • You might be happy to hear the blower going full tilt if it were truly design condition
    cold, but not every time it comes on!
  • The ecMModulator increases the blower’s speed as the temperature of the air coming from your
    registers gets warmer. You experience an air speed for each temperature that makes air movement
    difficult to feel.
  • During what would normally be the blower off period, you can run the blower very slowly so that air in
    your home remains constantly and silently mixed while all IAQ products work at peak efficiency.
 
Sudden full speed starts and high speed air movment through an air conditoning coil can strip water off the coil
and down the ductwork where it can contribute to mold growth. Avoidance of mold in HVAC systems is a growig
concern and takes a multi disciplined approach. The ecMModulator will not cure or prevent mold, but it will
contribute to it’s avoidance and control.
 
The next time your air conditioning gives you that hot and muggy or cool and clammy feeling or that musty sock smell. REMEMBER, you don’t have to put up with it. You won’t notice true comfort. It’s just there, from room to room, floor to ceiling and all the time.
 ColdWetCoil  
True whole home comfort and a healthyindoor environment are required ingredients of Indoor Air Quality! If you don’t feel that the your IAQ equip is giving you the results you expected, REMEMBER that you don’t have to put up with it. You can vastly improve IAQ equipment performance by having your present HVAC system brought up to date with an ecMModulator.
 
The ecMM odulator is not conspicuous consumption like the new “can you top this” spoke wheels, jet ski, camper
etc. Nobody will know but you and your family. A week after it’s installed in your present HVAC system, you’ll forget
it until you visit a friends home. Then you can tell them “YOU DON’T HAVE TO PUT UP WITH IT!”
 
 
CRUISE CONTROL FOR ZONED SYSTEMS
ELIMINATES THE INEFFICIENT, TROUBLESOME, NOISY, WATER
STRIPPING OFF THE COIL - BYPASS DAMPERS!
 
ECM ModulatorThe ecMModulator Model HVAC Whisperer 4-Z. Is the industry standard for controlling duct pressure in zoned HVAC systems. It can control the duct pressure in a zoned system to within 0.02” wc. It modulates the blower in response to the delivered air temperature, but will not modulate past the easily field-adjustable duct pressure setting. Because temperature controlled blower modulation doesn’t strip water off the coil during air conditioning, the blower can be run continuous in even the most hot and muggy climates. During the periods that the blower would normally be off, air is always moving silently at a gentle rate. Thus all IAQ products are working at a much higher efficiency.
Gentle and continuos air circulation levels out temperatures in the home which often results in the active zones being satisfied before the duct pressure limit is reached. Another very important result from the ecMModulator’s precise control is that the zone system will become less active with fewer opening and closings of zone dampers. Therefore the zone system fades into the background and responds to changes in thermostat settings, sun load and other weather related conditions. THERE IS NOT A ZONED SYSTEM THAT WAS EVER INSTALLED, OR EVER WILL BE INSTALLED THAT CANNOT BE VASTLY IMPROVED BY THE ecMM odulator HVAC/IAQ WHISPERER! PERIOD!!!!

Testimonials

  • Mr. Peters,

    just had the Fan Handler installed on 10/26/2010. The contractor recommended that I use the "fan on" option, immediately I noticed the drastic reduction in sound as the fan now runs on a super low and quiet mode all the time. The first thing I have to get used to is the fan running all the time, not the sound or lack of it, just the idea. My contractor put on one of your motor's as well and assured me that there was no issue. Now I just had to wait for it to get cold, as luck would have it there was summer like weather for the past few days. The temperature went down today and I got a chance to see what the product will do. I no longer have to reach for the remote every time my furnace comes on, and I have turned the thermostat from 73 degrees to 71 degrees. The heat has come on for very short periods of time and he temp seems to be maintained. I don't want to get to excited as it is early in the process, but if this is any indication of what I can expect I truly sorry I didn't discover you a lot sooner. I have just retired from law enforcement after 36 ½ so I am home all day to monitor its performance. I will contact you again once the cold weather has set in to advise you of my progress.

    Thanks from a new fan of Fan Handler.
