 ====== puu's MitsuRunner setup =====
-  * My Mitsurunner software on GitHub: https://github.com/kestopuu/mitsurunner/
+  * 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
