Seems to me that we need to start with a conversation about "scope" and desired results, specific enough that we can tell when we are moving in the correct direction.

EDIT: Below is a working list of inputs & outputs for the GPC (general purpose controller), based on desired functionality. Additions are invited.
Quote:
  • Relay for compressor
  • Relay for crank case heater
  • Relay for fan
  • Relay for 4way valve
  • Relay for ground loop circulation pump
  • Relay for hydronic circulation pump
  • Input for flow switch so i am sure that water is circulating
  • Input for an S0 power meter to measure power usage.
  • Input for frost sensor (or water HX output temp sensor)
  • Two rs485 bus lines one for outside sensor print, and one to
    communicate with my other heating controller.
  • 2x16 lcd display
  • Some led's and push button to test

Best,
