The ECL-PTU Series are microprocessor-based programmable controllers designed to control powered terminal units such as powered fan coil units, heat pumps units, and chilled beams. Additionally, these HVAC applications can support various pipe configurations such as 4-pipe, 2-pipe, and 4-pipe and 1-coil using a 6-way valve. These controllers use the LonTalk® communication protocol and are LONMARK certified as SCC Fan Coil controllers.
This series contains five models: ECL-PTU-107, ECL-PTU-207, ECL-PTU-208, ECL-PTU-307 and ECL-PTU-308. These controllers support various input types including resistance, voltage, pulse, and digital-based ones. Moreover, they provide analog, floating, and proportional control outputs for valves, electric heaters and fans. This series can control up to 8 lights and 8 shades / sunblinds through ECx-Light/Blind modules. These are expansion modules that operate off of a separate sub-bus, giving this controller the ability to manage lighting and shades / sunblinds for a full cross-management solution operating from a single network point.
These controllers work with a wide range of sensors, such as those in the Allure™ EC-Smart-Vue series of communicating room sensors that feature a backlit-display and graphical menus. These sensors are used for indoor temperature measurement, setpoint adjustment, fan speed selection, and occupancy override. Some models include CO2 sensing and motion detection to allow the system to adjust to actual operating conditions for increased energy savings. In addition, these controllers are Open-to-Wireless™ ready, and when paired with the Wireless Receiver, they work with a variety of wireless battery-less sensors and switches.
Custom program these controllers using EC-gfxProgram through either EC-NetAX™ Pro which is powered by the NiagaraAX Framework® or through any LNS®-based software such as Distech Controls’ Lonwatcher 3. This allows you to quickly and easily create your own control sequences capable of meeting the most demanding requirements of any engineering specification.
The number of applications for LonMark certification is growing rapidly. To make sure your products are on-track for certification, design conformance into them by following the LonMark Interoperability Guidelines v3.4.
The Proficiency Testing Program for Qualified Open Systems Installers, Professionals and Integrators provides a worldwide standard of proficiency for individuals that install, integrate and maintain systems utilizing LonMark certified products.
