Selecting The Right Control Solution

Every HVAC application has unique requirements. Omachron® Controls offers multiple factory-programmed fan coil control board configurations designed to accommodate standalone operation, centralized communication, and integrated ventilation control. Understanding the differences between available control platforms can help simplify specification, installation, and long-term operation.

Omachron offers four fan coil unit control board configurations designed to accommodate a variety of HVAC applications, communication requirements, and ventilation strategies.
RS-485 control enables networked communication and centralized management, while 7-wire control provides a conventional standalone control solution.
RS-485 control enables networked communication and centralized management, while 7-wire control provides a conventional standalone control solution.
Common applications include hotels, condominiums, apartments, student housing, retirement residences, and other multi-unit residential and commercial buildings.
Choose an integrated ERV model when your equipment needs to manage fan coil operation and energy recovery ventilation from a single platform. Both the 7-Wire FCU + Integrated ERV and RS-485 FCU + Integrated ERV models support this approach.
Confirm your equipment configuration, thermostat or room controller interface, fan and valve control requirements, protection inputs, and whether integrated ventilation is needed. Omachron® Controls can help match these requirements to the appropriate board configuration.

Engineered for Reliable HVAC Operation

Omachron® control boards combine microprocessor-based technology with dependable HVAC functionality to support a wide range of fan coil applications. Each board is designed with installers, OEMs, service technicians, and facility managers in mind, providing reliable operation and straightforward diagnostics.

All Omachron control boards utilize microprocessor-based control technology for reliable fan coil unit operation and system management.
The control boards support multiple fan speed outputs depending on the selected configuration and application requirements.
Onboard LED indicators provide system status information and assist with diagnostics and troubleshooting.
A 500-milliamp glass fuse protects the control circuitry from overcurrent conditions.
Omachron® control boards support flood detection, float switch monitoring, freeze protection, aquastat inputs, and auxiliary safety monitoring. Confirm the available inputs and operating sequence for your selected configuration.
Yes. The fan coil control platforms support heating and cooling valve outputs, with electric heat and additional control options available depending on the model. Integrated ERV configurations also offer ventilation control capabilities.
