HVAC Whisperer


- 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 dehumidifyany 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 IAQproducts functioning at peak efficiency. Can be set as low as 200 silent and draft free rpm for those periodswhen the blower would normally be off.
-
Has a 0 to 10 vdc output signal which allows control of frequency drives to modulate single phase orthree phase multiple horsepower pumps and large belt driven fans with the same results and features asresidential 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.

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.

- 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 airconditioner 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 upwith that hot and muggy feeling. So, you set the thermostat down and you end upwith the cool and clammy (smelly sock) situation.
-
Because of the programming of the ecMModulator, it forces your air conditioner towring the moisture out of the air. You remain comfortable and cool
-
At any time you are not experiencing heating design conditions, your HVAC systemis too large.
-
The blower starts and blows the same way that it would if it were the coldest dayof the year.
-
You might be happy to hear the blower going full tilt if it were truly design conditioncold, but not every time it comes on!
-
The ecMModulator increases the blower’s speed as the temperature of the air coming from yourregisters gets warmer. You experience an air speed for each temperature that makes air movementdifficult to feel.
-
During what would normally be the blower off period, you can run the blower very slowly so that air inyour home remains constantly and silently mixed while all IAQ products work at peak efficiency.
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. | ![]() |
True whole home comfort and a healthy indoor 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.
