Documentation

Start with the workflow, not with a random article.

This documentation area is organized around the order an HVAC engineer actually works: first connection, behavior model, machine log replay, control-quality review, reporting, and release checks.

Quick Start

Understand the first-launch path, the first Modbus connection, and the minimum checks before a real controller run.

Start here

Engineering Workflow

Follow the recommended daily testing path from connection through report export.

Core guide

Behavior Model Guide

Build realistic compressor response from field logs, engineer-estimated curves, model-specific behavior tables, and CSV trend-preview checks.

Choose Your Task

Guide the visitor by task, not by date.

Each guide should become a stable page with one clear purpose, not part of a blog-style archive.

I need to connect a controller and confirm communication.

Start with the quick start and engineering workflow. Use Basic Calculated Model if you need a fast first connection.

I need realistic compressor response across a wider operating range.

Use the Behavior Model Guide to combine field-log evidence, engineer-estimated completion, exact model behavior tables, and CSV trend-preview checks into a practical testing model.

I need to replay one recorded machine event exactly.

Use Machine Log Replay when the goal is reference comparison, regression confirmation, or proof that a captured event can be reproduced.

I need to judge command versus response during a run.

Use the Control Quality Monitor guide for signal presets, event timing, multi-compressor review, and report workflow.

I need repeatable release or regression checks.

Use Release Behavior Checks for scenario-based baseline confirmation after code or configuration changes.

I need product, pricing, or support context around the guide.

Use the product page, pricing page, and support page together so the visitor can move naturally from understanding to adoption.

Learning Path

Use the written guides and published videos together.

Start with the written guide that matches the task. Use the available setup videos for installation and Modbus connection checks, then use support if a project needs direct help.

Start with installation

Use the Quick Start guide and Download page when the goal is installation, first launch, Machine ID, and trial license activation.

Choose the right simulation path

Use Engineering Workflow to decide between live values, behavior modeling, machine log replay, and release checks.

Prepare useful support details

Use the Support page to package the release number, scenario, expected result, actual result, reports, logs, and screenshots.

Request installer access

Use the Download page to request installer access first, then request the machine-bound 14-day trial license after first launch.

Video Tutorials

Published videos and related guides.

Setup videos are available now. Behavior-model and monitor videos remain linked to the written guides until those tutorials are published.

Need installer access?

Request the installer first. After first launch, copy the Machine ID and request the 14-day trial license from the Download page.

Need direct help?

Send a support request with the release number, compressor type, scenario, expected result, actual result, and relevant screenshots or reports.

Next Step

Need the product, the guide, or direct help?

Documentation gets the first test running. Pricing explains the commercial model. Support handles the cases that need direct interaction or video guidance.
