Zone Controller

Automated Logic’s ZN253 provides unprecedented power and flexibility through fully programmable networked controllers. The ZN253 controllers connect to the Building Automation System (BAS) network using BACnet over ARCNET 156 kbps or MS/TP. The ZN253 supports a line of RS room sensors using its Rnet port.

Zone Controller

Automated Logic’s ZN220 provides unprecedented power and flexibility through fully programmable networked controllers. The ZN220 controllers connect to the Building Automation System (BAS) network using BACnet over ARCNET 156 kbps or MS/TP. The ZN220 supports a line of RS room sensors using its Rnet port.

Rugged Flexibility for Single Equipment Applications

Automated Logic’s powerful SE line provides a rugged solution for single equipment applications. Designed to operate in a wide range of environmental conditions, SE controllers can be used in rooftop units, mechanical rooms, equipment closets, or almost any other weather tight location. Fully programmable using the EIKON® graphic programming language, SE controllers use native BACnet communications over either a high-speed ARCNET 156 kbps network or a medium speed MS/TP network to provide maximum flexibility and interoperability.

Multi-Equipment Application Controllers

M Line controllers are ideal for multi-equipment applications in commercial environments. These robust standalone controllers utilize native BACnet communications over a high-speed ARCNET 156 kbps network to ensure superior performance.

Powerful Multi-Equipment Controllers

ME 812U Line – Powerful Multi-Equipment Controllers

The ME812U controllers have the speed, power, memory, and I/O flexibility to handle the most demanding control applications in the industry. Capable of controlling multiple pieces of equipment simultaneously, this robust BACnet controller can support complex control strategies with plenty of memory for trends, and is capable of third party integration using other communication protocols.

Universally Understood Graphical Programming

EIKON-LogicBuilder for WebCTRL is the most advanced graphical programming tool in the industry. With the click of a button, you can build complex control algorithms, diagnose problems, and run real-time or simulated operational data to evaluate the performance of a control sequence. EIKON-LogicBuilder makes it easy to understand control sequences as it does not use cryptic “line by line” computer code.

Key Features and Benefits

Intuitive graphical programming tool eliminates the need for complex programming or cryptic computer code.

Powerful library of microblocks (control functions) provide the flexibility to develop simple and complex control sequences.

Universally understood graphic symbols make control algorithms easy to understand.

Flexible simulation mode enables the user to view the control routines before system installation which simplifies development and troubleshooting.

Live Graphic Function Blocks (GFBs) are a valuable troubleshooting tool that allow system performance to be viewed in real time.

Time-Lapse Graphics™ is a revolutionary new feature within WebCTRL that allows operators to roll back time, up to a 24-hour slice, and play back hours of real-time data in just minutes. This innovative feature provides a quick, visual indication of any problem areas and gives facility managers a strong diagnostic tool to quickly identify and correct issues that impact energy efficiency and comfort.

Our Environmental Index™ provides a simple and effective solution. Starting with temperature as a key component of comfort, the Environmental Index (EI), expressed as a percentage, reflects how close the zone temperature is to the effective heating and cooling setpoints. Accessed through a browser using WebCTRL, the EI is shown on an easily read analog gauge, using the red segments to indicate poor environments, and graduating to green as conditions improve and the EI begins to approach 100%.

ALC’s EnergyReports™ is a flexible, easy-to-use reporting tool that enables facility managers to produce a wide variety of reports showing a building’s energy consumption. Using color graphs, EnergyReports allows users to compare energy consumption or demand over different periods with simple drop-down menus and calendar control options. This gives facility managers a powerful tool to minimize energy consumption, maximize comfort, and achieve sustainable building operations.

EIKON® – LogicBuilder, the most advanced graphical programming tool in the industry, replaced line-by-line programming with universally understood symbols to construct both standard and custom control algorithms. All of this combines to make the most intuitive, feature-rich, easy-to-use product on the market.
