Entronix continuously analyzes BAS, equipment, and operational data to identify abnormal conditions, equipment issues, and performance gaps.
Your BAS Has the Data. Entronix Finds the Problems.
Building Automation Systems generate thousands of values every day. Temperatures. Commands. Setpoints. Valve positions. Fan status. Pressures. Schedules. Alarms. The challenge is that engineers cannot continuously review every point.
Entronix safely brings BAS data into the platform and evaluates it against defined operating rules. When conditions violate those rules, Entronix identifies the issue and brings it to the team's attention.
AHU-3 is commanded ON but the fan reports OFF. Rule AHU-07 opened an FDD issue at 09:14.
The result: earlier detection, faster troubleshooting, fewer hidden problems, and better equipment performance.
How Entronix FDD Works
Connect. Evaluate. Detect. Act.
- 01Connect
Bring operational data from BAS platforms, equipment, meters, sensors, and other connected systems into Entronix.
- 02Evaluate
Continuously compare live operating data against predefined or user-created rules.
- 03Detect
Identify faults, abnormal conditions, equipment exceptions, and performance anomalies.
- 04Act
Prioritize issues, notify the appropriate team, investigate the cause, and track corrective action.
Rules Built Around Your Operations
Define What “Normal” Means.
Every facility operates differently. Equipment sequences, schedules, setpoints, environmental requirements, and engineering standards vary by building and organization.
Entronix allows users to create rules around those requirements. A rule can continuously watch one or multiple data points and determine when operating conditions fall outside expected behavior.
Example
Another example
The rules can reflect the way your organization believes the system should operate.
Create Your Own FDD Rules
Your Equipment. Your Standards. Your Logic.
Entronix gives engineering teams the ability to define the conditions they want the platform to monitor.
Rules may use:
- Equipment status
- Commands
- Setpoints
- Temperatures
- Pressures
- Flow
- Valve position
- Damper position
- Electrical current
- Runtime
- Schedules
- Energy consumption
- Outdoor conditions
- Multiple related points
Flag an issue when Supply air temp > setpoint + 5°F while fan command is ON for more than 5 minutes, then wait 10 minutes before alarming, but suppress it during startup.
Define the logic once. Entronix watches it continuously.
What Entronix Can Look For
Detect Problems That Are Easy to Miss.
Examples of FDD rules may include:
- 01Simultaneous Heating & Cooling
Identify equipment heating and cooling at the same time.
- 02Equipment Not Responding
Detect when equipment is commanded ON but operating status does not confirm operation.
- 03Sensor Problems
Identify values that are stuck, unrealistic, or inconsistent with related sensors.
- 04Schedule Exceptions
Find equipment operating outside expected schedules.
- 05Temperature Performance
Identify systems that cannot maintain expected supply, return, or space conditions.
- 06Valve & Damper Exceptions
Detect commanded positions that do not produce the expected operational response.
- 07Excessive Runtime
Identify equipment operating longer than expected.
- 08Short Cycling
Detect repeated ON/OFF operation over short periods.
- 09Abnormal Energy Use
Identify unexpected consumption relative to equipment or operating conditions.
- 10Performance Degradation
Detect gradual changes that may indicate declining equipment performance.
Fault Detection Capabilities
Continuous Intelligence Across Operations.
Automated Fault Detection
Continuously evaluate connected operational data instead of relying on manual review.
Safely Connect to Existing BAS
Add Intelligence Without Replacing Your Controls.
Entronix FDD sits above existing Building Automation Systems.
The BAS continues doing what it was designed to do: control the building.
Entronix securely collects the operational information needed for monitoring, analysis, and fault detection.
This may include data from:
- BACnet systems
- Modbus systems
- Building Automation Systems
- Equipment controllers
- IoT sensors
- Meters
- Entronix Core
- Other supported data sources
Keep the control system. Add an intelligence layer above it.
From Fault to Root Cause
Give Engineers More Than an Alarm.
An alarm tells the engineer that something happened. FDD should help explain the condition. Entronix can bring together:
- Started09:14 today
- Duration22 min, ongoing
- StatusOpen, assigned to Plant team
This allows engineers to see:
- Which rule was violated
- Which equipment is involved
- What values triggered the issue
- How long the condition existed
- Whether the issue is recurring
- What related points were doing
Less searching. More context. Faster troubleshooting.
Fault History
Know Whether the Problem Is New, or Keeps Coming Back.
Some operational problems occur once. Others happen every day.
Entronix keeps historical fault information so engineering teams can understand patterns over time.
12 weeks · each square is one day · orange means the fault occurred
Recurring fault · resolution open
Track: First occurrence, Last occurrence, Frequency, Duration, Affected equipment, Historical conditions, Recurring faults, Resolution status.
This helps teams distinguish between isolated events and systemic problems.
Prioritize What Matters
Not Every Fault Has the Same Impact.
A building can generate hundreds of potential issues.
Entronix helps teams organize and prioritize findings based on factors such as:
Pick the factors that matter to your team. The list re-ranks.
- High · AHU-3 · Commanded ON, fan status OFF10.0
- High · AHU-7 · Simultaneous heating and cooling10.0
- Medium · VAV 4-12 · Zone temp sensor stuck at 73.9°F8.8
- Medium · CH-2 · Condenser water ΔT low7.5
- Low · EF-2 · Running outside schedule7.5
- Low · Boiler 1 · Short cycling, 14 starts per hour6.3
Engineering teams can focus first on the issues that matter most.
FDD Across Every Level
From One Piece of Equipment to the Enterprise.
- 01Enterprise
See fault trends, recurring issues, and performance patterns across the organization.
- 02Portfolio
Compare facilities, regions, campuses, or operating groups.
- 03Facility
Understand active and historical faults within a building.
- 04System
Analyze HVAC, electrical, mechanical, or other connected systems.
- 05Equipment
Review individual equipment faults and operating history.
- 06Rule
See exactly which condition was violated and why.
One Rule Across the Portfolio
Standardize Engineering Expectations.
A powerful advantage of a centralized FDD platform is the ability to establish common operating standards.
For example: create one rule for simultaneous heating and cooling. Then apply it to:
Define once. Monitor everywhere.
Rules + Analytics + AI
Let Technology Watch What Humans Cannot.
The foundation of Entronix FDD is continuous operational logic. Rules identify when defined conditions are violated. Analytics provide historical and performance context. AI can help engineering teams understand and summarize what the system is finding.
- Detect
Continuously evaluate operational conditions.
- Correlate
Connect related data points and equipment behavior.
- Prioritize
Surface the problems most worthy of attention.
- Explain
Summarize what happened and why it may matter.
- Report
Turn faults and trends into management-ready information.
Engineers define how the system should operate. Entronix helps watch it continuously.
Turn Engineering Knowledge Into Software.
Experienced engineers know what to look for. They know that a certain temperature relationship indicates a problem. They know when a valve position does not make sense. They know when equipment behavior is abnormal.
But that knowledge often exists only in someone's experience.
In someone's experience
If the valve is wide open and the room still won't cool, something upstream is wrong.
