ACxelerate™ Automated Commissioning Tool
The ACxelerate™ Automated Commissioning Tool (ACx) assists in commissioning VAV terminal units by automating many commissioning tasks, reducing field and facility commissioning time and callback rate by:
- Discovering VAV boxes and their cooling sources in a WebCTRL system
- Allowing a dealer to schedule a set of functional tests that automatically and safely exercise VAV dampers and/or reheat valves by mechanical system
- Analyzing the functional test results
- Generating a report that documents both healthy system operation and faults
The new ACxelerate auto-commissioning tool is an add-on to the WebCTRL® v7 building automation system (BAS), and can be used to test single-duct, dual duct and fan-powered (series and parallel) VAV terminal unit dampers and reheat valves. Automated testing is ideal for VAV terminal units due to quantity, location and the difficulty in accessing them. The ACxelerate tool has been tested on all types of buildings, and has been shown to substantially reduce commissioning time. Days-to-weeks scenarios have turned into hours.
Key Features and Benefits
Application Features
• Discovers VAV boxes and their cooling sources in a WebCTRL
• Designs and schedules a set of functional tests that safely and automatically exercise VAV dampers and/or reheat valves in the mechanical system
• Analyzes the functional test results and generates a report that documents both healthy system operations and faults
• Displays all VAV functional test results and highlights failed and passed tests in an intuitive dashboard
• Exports report files in HTML or Excel format
Supported Applications
The following applications include logic symbols to exercise VAV terminal unit dampers and reheat valves:
• Single-duct VAV
• Dual-duct VAV (one duct at a time)
• Fan-powered VAV for series and parallel fan configurations in occupied mode (ACx does not control or test fan operation)
