This is a great project i really like to join.
For my own HP i was already started to design and make the circuit on breadboard. My idea was to place this print inside the house next to the HX and run a cable to control the outside components.
The things I want on my board:
-Relay for compressor
-Relay for fan
-Relay for 4way valve
-Relay for circulation pump
-input for flow switch so i am sure that water is circulating
-input for an S0 power meter to measure power usage.
-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
My idea was to control everything with the arduino nano. Witch is just a arduino uno but then smaller and easy to include on you own circuit board.
I designed circuit boards before and make the first prints at home.
I have very good experience with one wire sensors i use them also for my wood stove system for all the sensors it only require one input of an arduino.
I think it is an good idea to make an list of the outputs we want, and a list for the inputs the functions are "software issues" but also good to place them in a third list!
