The ECM Modulator 4


The ECM Modulator 4 package

This package is a great upgrade for any residential HVAC System, as well as many commercial units. Can be used with just about any make/model of furnace or heatpump, and allows you to upgrade from outdated PSC or X-13 stayle motors to an advanced temperature controlled variable speed system.

What you can expect from the ECM 4

With the ECM Modulator installed, your customers will notice vastly improved comfort; while experiencing improved indoor air quality, noise reduction, and energy efficiency.

This system has been designed to improve the overall performance of any existing Heat Pump or Furnace, to compete with or exceed the performance of modern equipment, at a fraction of the cost.

These amazing benefits are achieved as the ECM 4 monitors the units delivered air temperature, and continually adjusts the airflow to meet the need of the system. Correct air flow is key to system performance and lifespan. No other system controls the blower the way we do and that's why no other system can match our performance.

Blower speed reduction

Small reductions in fan speed = big savings. The ECM Modulator provides impressive energy savings by intelligently adapting the fan speed to the temperature of the air being delivered to the home. This greatly reduces the average energy consumption during the times that ambient conditions do not require full speed operation. While many manufactures are starting to adopt variable speed systems, FanHandler is the only one that uses the delivered air temperature for speed control. This allows us to safely run the blower at much more efficient speeds.

Blower motor upgrade 

The ECM4 and 4Z packages allow you to upgrade systems with existing PSC or x-13 style motors, to use a high efficiency variable speed ECM. By upgrading these outdated systems with an ECM 4 or 4Z package, your customers can see energy savings of 30% or more. For more information check out our Energy Savings Page.

Other uses

Commercial Applications

The ECM Modulator controls have a 0-10V output that can be used with a frequency drive to control blowers of just about any size in large industrial or commercial applications.

ECM Modulators can be used for more than just air flow.

Circulating pumps, and modulating valves that have a 0-10V or PWM input can also be used with ECM Modulators to regulate flow in response to temperature changes. If you have an application where you want prices temperature control. let us know we can program the heating on cooling ramps to meet your specific needs.

Ventilation applications

The ECM Modulators have been used in a wide variety of ventilation systems to regulate everything from building pressures, to regulating ammonia levels in chicken farms. If you have ventilation system that requires precise control let us know. We are happy to adapt the control to your specific needs.

Fan coil applications

The ECM Modulators can take a 0-10V input from a thermostat to regulate the fan speed in response to the difference between the return air and the thermostats set point. This gives an economical way to upgrade fan coil units to be automatically adjusting.

The ECM Modulators are extremely versatile and have multiple auxiliary inputs and outputs that can be programmed for your application. So, whether you are trying to maintain a specific delta, regulate air flow, water flow, damper position or you have a new idea of your own you want to try out. Please let us know. We are here to help!
