Eubank’s proprietary Printed Circuit Board (PCB) sets the standard for the industry in flexibility,
reliability and performance. This UL certified component is engineered to optimize Heating, Cooling and
Dehumidification operation while communicating valuable information to the end user. Special features
include 2-Stage operation with varying speed control to optimize latent and sensible capacity, built in
remote communication (Modbus) for monitoring and/or control, optimized head pressure control and
configurable menu options for various operations and control. The Eubank PCB comes equipped with
seven segment display to annunciate faults, which drastically reduces troubleshooting time and system
downtime. Lockout contacts are also provided along with the alarms being transferred via Modbus.
