We are excited to announce the release of the WebCTRL® system Fault Detection and Diagnostics Phase II SAL
|Initially introduced with WebCTRL v6.0, the latest release of the Automated Logic Fault Detection and Diagnostics (FDD) library can now pinpoint over 100 proven faults in typical HVAC equipment, including VAV systems, air handlers, fan coils, unit ventilators, water-source heat pumps, and air-source heat pumps.
The logic for the equipment types listed below includes the following types of faults in the FDD alarm category
The logic in this library generates FDD alarms to warn users of problems which may be causing equipment to run inefficiently, wasting energy and/or degrading occupant comfort. The Department of Energy estimates FDD alarming could reduce energy use by up to 15%, and the State of California now requires FDD alarming in the Economizer section of certain rooftop units.
Examples of problems that this logic will detect include:
- Leaking Heating Valves: A worn valve seat or a misadjusted actuator can cause a heating valve to “leak” hot water to the coil even when it is commanded 100% shut. This wastes heating energy and can bring on additional cooling, which wastes cooling energy. The FDD logic generates an alarm if there is a significant heat rise across a closed coil.
- Failed DX stage: In a multi-stage DX unit, if one cooling stage fails, the controls will bring on additional stages as needed to provide the required cooling. The user will not even be aware of the failed stage until the weather gets really hot and the unit can no longer provide sufficient cooling without that stage. Then repairing or replacing that stage becomes an emergency. The FDD logic monitors each stage as it is commanded on, and generates an alarm if any one stage fails to provide cooling. Repairs can be undertaken on a routine basis, while the building is still comfortable.
- Continuous Running: For a typical building, one of the most effective ways to save energy is to make zones “unoccupied” and turn equipment off at night and over weekends when no one is using the building. Unfortunately, a common problem with building automation systems is the existence of “rogue” schedules, locked points, and other overrides which unintentionally cause systems to run even when unoccupied. These problems often go unnoticed because no one is in the building at the time. The FDD logic monitors zone runtime and generates an alarm if it exceeds a certain number of hours per day. By default the trip point is set at 23 hours, but it can easily be changed to a shorter time for zones that should only be occupied fewer hours.
WebCTRL® System Automated Demand Response Add-on
The WebCTRL system Automated Demand Response add-on is a software application that allows buildings using the Automated Logic® WebCTRL system to communicate with utility companies.
The WebCTRL system Automated Demand Response add-on supports OpenADR 2.0 and enables the WebCTRL system to participate as a virtual end node (VEN) in various utilities’ Automated Demand Response (ADR) programs. Each program produces specific signals that notify of upcoming demand events. An ADR event from the utility can have one or more signal types in it, such as Simple or Load Control.
Demand-reduction actions are prioritized and programmed into the software’s control logic. The WebCTRL system Automated Demand Response add-on converts the raw OpenADR signals into information which the software can use to implement the required demand reduction.
The Automated Logic® WebCTRL® building automation system is a proven, industry-leading system that gives you the ability to fully understand your operations and analyze the results with tools that make sense to you. The WebCTRL system fully supports the OpenADR 2.0a and 2.0b with the WebCTRL system Automated Demand Response add-on.
Look at your building automation system as the gathering place, the repository of all operating data and information related to your building. Whether it is temperature history, utility load shedding, trend data or comfort measurement, your WebCTRL system effectively packages the information you need for management of your facilities.
Key points about OpenADR:
- Allows electric utilities to accommodate short increases in peak demand without building expensive new power generation plants or imposing rolling brownouts or blackouts.
- Allows consumers to increase their energy saving plans through pre‐planned reductions in energy consumption for short periods of time.
- Allows system operators, such as Independent System Operators and utilities, to use customers’ load as a resource to balance the electric grid.
- Can be either discretionary in response to a temporary increase in pricing, or automatic as part of an existing arrangement between the customer and the utility, or both (with opt‐out under non‐emergency conditions).
- Provides consistency in communicating the ADR event while facilitating faster responses that translate into greater energy savings and more options for combining energy resources, which helps keep prices lower for everyone.
- Provides pricing continuity between wholesale (generation and transmission) and retail (distribution) markets.
- Provides both a common language and a common platform for all providers and consumers of ADR through the functions and features of a Demand Response Automation Server (DRAS).
MaintenanceLog is an Add-On to WebCTRL6.0 and 6.1 that provides a way for your techs and staff to save maintenance and repair records for each item of equipment under control in WebCTRL. When the graphic is accessed, a blank log page will appear, and it will provide the means to enter a new record for that equipment in WebCTRL, which will be saved in a Derby database. After entering records for the equipment, the records will continue to show for that equipment, with the newest maintenance log at the top. On each individual equipment graphic page, there is a means to filter the records by date or operator. There also is a page that displays all records in the system, which also has filtering options as well. The Help file is accessible from any log page, or by typing http://yoursystemURL/MaintenanceLog. Contact your local WebCTRL system provider and get to logging!
