HeishaMon Cascade Control

Overview

HeishaMonKaskade is a specialized variant of the HeishaMon firmware designed for cascade installations where multiple Panasonic Aquarea heat pumps work together. It coordinates operation across units to optimize efficiency, balance runtime, and manage staging.

Features

• Multi-Unit Coordination: Manages multiple heat pumps as a single system
• Load Balancing: Distributes heating load across units to equalize wear and optimize COP
• Staged Operation: Intelligently stages units on and off based on heating demand
• Individual Monitoring: Tracks each heat pump's telemetry independently via MQTT
• Cascade Logic: Built-in rules for cascade sequencing, lead/lag rotation, and demand-based staging

Use Cases

• Commercial buildings with multiple Panasonic Aquarea units
• Large residential properties requiring more heating capacity than a single unit provides
• Retrofit installations where cascade control replaces Panasonic's proprietary cascade controller

Requirements

• One HeishaMon PCB per heat pump in the cascade
• MQTT broker for inter-unit communication
• Panasonic Aquarea heat pumps with CN-CNT interface

This project addresses a niche but important use case for larger installations where factory cascade controllers are expensive or inflexible.
