CO2 sensors

CO2 sensors as part of a demand-controlled ventilation strategy that adjusts the amount of fresh air intake according to the number of building occupants

Variable-frequency

Variable-frequency drives to adjust motor speed according to the instantaneous demand of the application.

Universal Inputs and Outputs

This controller has various software configurable universal inputs and software configurable universal outputs, and covers all medium to large-size industry-standard HVAC applications. This series supports up to two ECx-400 Series I/ O extension modules that operate off of a separate sub-bus, giving this controller a total of up to 40 universal inputs and 36 universal outputs.

HOA Switches & Potentiometers

Certain models have the convenience of supervised Hand-Off-Auto (HOA) switches and potentiometers that provide feedback on an operator’s manual override of an output to the controller’s code. HOA switches are ideal for testing purposes or when performing equipment commissioning and maintenance.
