puu's MitsuRunner setup
- My slightly modified MitsuRunner software on GitHub: https://github.com/kestopuu/mitsurunner/
Notable changes to the original SW and HW:
- Two additional Dallas sensors in heat exchanger pipes (used for research and as spare parts)
- Current clamp sensor monitoring input power of the heat pump
- Variable temperature delta threshold to start defrosting:
- if (input) power < 900W, threshold = 4
- if 900W ⇐ power < 1400W, threshold = 5
- if power >= 1400W, threshold = 6
