2.WIRING - Another important difference in the replacement of an “ESU” model with a new “S” series humidifier is the wiring connections. On the “ESU” the humidity control was connected to the two ‘WHITE” wires on the molded plug. When upgrading to the “S” series, simply cut the two white wires and connect them to the two “H” terminals on the top of the front cover.

The blower (fan) interlock was connected via the two red wires on the old “ESU” model and usually incorporated a field installed transformer and interlocking relay. Just cut the two red wires and connect them to the “R” and “G2” terminals on the top of the front cover. In this method you can reuse the field relay and transformer which were originally installed with the ESU.

If this is a new install then you can fully utilize the on board relay provided with the “S” series humidifier and interlock your blower “fan” by following the low voltage diagram. There is no need to install a separate transformer or relay.

DO NOT plug the molex connector from the old “ESU” humidifier, into the socket on the side of the front cover on the new “S” series humidifier. That socket connection is now reserved for the automatic drain valve only. Doing so will damage the unit and void the warranty.

ESU14 specifications

The Field Controls ESU14 is an advanced air quality solution designed to enhance indoor environments by providing superior filtration and purification capabilities. Built for both residential and commercial applications, the ESU14 stands out due to its innovative features and technologies that ensure cleaner air and improved comfort.

One of the main features of the ESU14 is its high-efficiency particulate air (HEPA) filtration system. This system captures up to 99.97% of airborne particles, including dust, pollen, allergens, and even some viruses and bacteria, as small as 0.3 microns. The HEPA filter's efficiency not only aids in maintaining better air quality but also contributes to reducing respiratory issues for occupants, making it a vital addition for homes with allergy sufferers or those sensitive to air pollutants.

Additionally, the ESU14 utilizes advanced ultraviolet (UV) light technology. This technology helps to neutralize harmful microorganisms that may be present in the air or within the HVAC system. The UV lights work to disinfect the air, improving overall air quality and ensuring a healthier environment. This makes the ESU14 an ideal choice for spaces that require stringent hygiene standards, such as healthcare facilities or daycares.

Another significant characteristic of the ESU14 is its user-friendly interface. The system is designed for easy operation, allowing users to monitor air quality levels and system performance with minimal hassle. With smart technology integration, the ESU14 is compatible with various home automation systems, allowing for seamless control via smartphone apps or through voice-activated devices.

The ESU14 is also engineered with energy efficiency in mind. By optimizing airflow and reducing energy consumption, it minimizes operational costs while effectively purifying the air. Its durable construction ensures a long lifespan, and routine maintenance is straightforward, making it a practical choice for long-term air quality management.

In summary, the Field Controls ESU14 combines high-efficiency HEPA filtration with cutting-edge UV technology to deliver an effective air purification solution. Its user-friendly features, energy-efficient design, and robust performance make it a top choice for those seeking to improve indoor air quality while promoting a healthier living or working environment.
