The ECL-3400 can also be used for lighting control and power measurement applications. This controller uses the LonTalk® communication protocol and is LONMARK certified as a Static Programmable Device, guaranteeing compatibility and interoperability with other manufacturers’ LONMARK certified controllers.
These controllers meet the requirements of the following applications:
Air handling units
Roof top units
This controller has various software configurable universal inputs and software configurable universal outputs, and covers all medium to large-size industry-standard HVAC applications.
Rugged hardware inputs and outputs eliminate need for external protection components, such as diodes for 12V DC relays.
Open to Wireless
The controllers are Open-to-Wireless™ ready, and when paired with the Wireless Receiver, work with a variety of wireless battery-less sensors and switches, to reduce the cost of installation and minimize the impact on existing partition walls. Available with an optional Wireless Receiver that supports up to 28 wireless inputs to create wire-free installations.
Highly Accurate Universal Inputs
Highly accurate universal inputs support thermistors and resistance temperature detectors (RTDs) that range from 0 Ohms to 350,000 Ohms, as well as support for inputs requiring 0 to 10VDC or a pulse count. 0-20mA inputs and outputs have a jumper that eliminates the need for external resistors. This provides the freedom of using your preferred or engineer-specified sensors, in addition to any existing ones. The first four universal inputs support fast pulse count reading up to 50 Hz for gas, water, and electric meters and are compatible with an SO rated (optically-isolated) output.
Increased Energy Efficiency
Improves energy efficiency when combined with:
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 drives to adjust motor speed according to the instantaneous demand of the application.
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.
Lights, Blinds and Air Temperature. Our extensive range covers all aspects of room control and beyond, from single controllers to wall fitted thermostats.
