About This Library

Welcome to the heart of our system-level logic and control strategies. This library contains comprehensive Sequence of Operations (SOO) documents for common Building Automation System applications and equipment. Unlike our SSO library which focuses on individual device installation and proof-out, these SOO documents detail the how and why of an entire system’s operation, control logic, interlocks, and performance verification.

Each SOO is designed for field engineers, programmers, and commissioning specialists and includes:

  • System overview and design intent
  • Detailed control sequences (start-up, normal operation, shutdown, economizer, etc.)
  • Points list with typical naming conventions
  • Operating parameters and setpoints
  • Interlocks and safety protocols
  • System proof-out and commissioning procedures
  • Troubleshooting common operational issues
  • Performance optimization strategies

Format: Comprehensive, logical flow, application-focused
Target Users: Field Specialists, Programmers, Project Managers, Commissioning Agents

Available SOO Documents

TEMPLATE

  • SOO Template - Standard format template for creating new Sequence of Operations documents for systems.

AIR HANDLING UNITS (AHU)

  • SOO AHU - Comprehensive sequence for Constant Volume and Variable Air Volume Air Handling Units.
    • Includes supply fan control, economizer operation, heating/cooling coil control, static pressure reset, and occupancy scheduling.
    • Key components: Supply Fan VFD, OA/RA/EA dampers, heating coil valve, cooling coil valve.

VARIABLE AIR VOLUME (VAV) SYSTEMS

  • SOO VAV Box - Detailed sequence for single-duct VAV boxes, including reheat and fan-powered variants.
    • Covers zone temperature control, VAV damper operation, fan control (if applicable), and reheat control.
    • Key components: VAV damper actuator, reheat coil, occupancy sensor integration.

CHILLED WATER SYSTEMS (CHWS)

  • SOO Chilled Water System - Sequence for manually-started chilled water systems with automated monitoring and pressure control.
    • Covers pump and chiller monitoring, differential pressure bypass valve control, and automated glycol make-up.

HOT WATER SYSTEMS (HWS)

  • SOO Hot Water System - Sequence for hot water systems with OAT-based automatic start and temperature reset.
    • Covers heat exchanger control, differential pressure bypass, and automated glycol make-up.

Document Organization

File Naming Convention

  • SOO-[SystemType]-[Descriptor].md

How to Use This Library

For Field Specialists

  1. Review the relevant SOO before commissioning a system.
  2. Understand the control logic and expected system behavior.
  3. Utilize the System Proof-out and Commissioning Procedures for thorough verification.
  4. Reference Troubleshooting for operational discrepancies.

For Programmers

  1. Use SOOs as the definitive guide for developing and implementing control logic.
  2. Ensure your code precisely matches the specified sequences, points lists, and interlocks.
  3. Reference Operating Parameters and Setpoints for configuration.

For Project Managers

  1. Leverage SOOs for project scope definition and client expectation setting.
  2. Ensure that system design and implementation align with documented sequences.
  3. Use for quality control and verification during project handover.

For New Hires & Training

  1. Study SOOs to gain a deeper understanding of integrated system control.
  2. Connect individual device functions (from SSOs) to overall system operation.

Feedback & Continuous Improvement

Report Issues

  • Errors or Omissions: Submit via Service Fusion ticket to Technical Training.
  • Suggested Improvements: Email [training@example.com].
  • New System Requests: Request SOO for systems not in library.

Revision Process

  1. Field feedback collected quarterly.
  2. Technical review by senior specialists.
  3. Updates approved by Technical Lead.
  4. New version published and distributed.
  5. Notification sent to all relevant staff.

Safety Notice

⚠️ CRITICAL SAFETY REMINDERS

  • Always prioritize safety: These documents detail operational sequences, but always adhere to all safety protocols, Lockout/Tagout procedures, and company policies.
  • Verify all interlocks: Ensure all safety interlocks are functioning correctly before initiating system operation.
  • Qualified personnel: Only qualified personnel should perform work on operational systems.
  • When in doubt, ask: Never proceed if unsure about a system’s behavior or safety implications.

Your safety and the safe operation of our systems are paramount.
