Digi-Touch

Digital Device Network for Lighting Control

Automated Logic’s Digi-Touch® Network dramatically reduces installation and wiring costs of field input devices, while increasing functionality of lighting switches. The Digi-Touch Network allows addressable Digi-Touch wall switches and Digi-Touch Input Modules to communicate with the LC series of Lighting Control Panels.

Optional VAV Accessories for use with ZN Line modules

The ZASF is part of a family of control modules designed specifically for VAV terminal box applications. It is designed to be used with the ZN341v+ and ZN141v+. It mounts directly on the secondary VAV damper shaft and provides an integral actuator and a second integrated flow sensor for damper positioning and air-flow sensing in dual duct or tracking systems.

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 Gateway

Automated Logic’s Equipment Portal (EQ-PRTL) sets a new standard for integrating other manufacturers’ equipment into WebCTRL®. EQ-PRTL is a powerful gateway to a single piece of equipment /device using proprietary or open protocols such as Modbus and LonWorks. Support for BACnet® over ARCNET 156 kbps and MS/TP communications are standard.

Balancing Efficiency with Comfort

WebCTRL Environmental Index – Balancing Efficiency With Comfort

As energy prices continue to soar, facility managers are under increasing pressure to find ways to cut building operating costs. A simple solution would be to decrease energy consumption, but smart managers know that sacrificing comfort for energy savings could lead to even bigger financial problems. After all, studies have shown productivity decreases as comfort levels decline, leading to lost revenues in companies and difficult learning environments in school systems. What’s needed is a way to measure comfort, so managers would know exactly how far to cut energy usage without negatively impacting comfort.

Automated Logic’s Environmental Index provides the solution. Since the key component of comfort is temperature, ALC’s index starts with assigning point values based on the difference between zone temperature and heating and cooling set points. Other factors, such as humidity and CO2 levels, can also be computed into the numeric system to reflect one “comfort” score for all factors. This is a powerful tool for facility managers who need to identify buildings with performance problems or ensure buildings don’t become less efficient as changes are made.

Software

Automated Logic has long been known for its intuitive, powerful front-end building control software. In fact, ALC pioneered graphical programming in the industry. With our graphical user interface, users have such features as hierarchical scheduling, thermographic color floor plans, trending, alarm management, and reporting. And withWebCTRL®, our web-based building automation system, all of these features are available through a standard web browser – without any special software or plug-ins.

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.
