====== 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 < 500W, threshold = 4
    * if 900W <= power < 1000W, threshold = 5
    * if power >= 1000W, threshold = 6
