Prompt Chaining Activity Diagram

Note - It is very experimental but working and subject to change once better methods can be created. TODO research MCP server to burn less tokens currently it uses LOTS of tokens in the context files sent to LLM service.

Of course. Here is a conceptual model and implementation for an AHU Fault Condition 1 hook based on the Normal Framework (NF) architecture, designed for reusability across your other fault detection rules.

This approach translates the logic from your Python script into a serverless JavaScript function (a "hook") that runs within the NF environment. It operates on real-time data points, using configurable variables for thresholds, which is ideal for a scalable Fault Detection and Diagnostics (FDD) application.

Hook Definition (`fc01-ahu-low-static.json`)

First, you define the hook's configuration. This JSON file tells the Normal runtime what data to select, how to group it, when to run the code, and what settings (variables) to make available. Each fault condition will have its own definition file.

❄️ Supply Air Temperature Reset – ASHRAE G36 Trim & Respond

This logic implements a modular supply air temperature reset strategy based on ASHRAE Guideline 36, section 5.16.2. VAVs issue SAT requests based on zone-level temperature demand, which are summed and used by the AHU to reset the discharge air temperature via trim and respond logic.

1️⃣ VAV Cooling Request – `sat-calculate-requests.hook.js`

Each VAV compares zone temperature against the occupied cooling setpoint and determines how many SAT reset requests to send.
