I am trying to get a general idea of what I am looking for. I am building a radiant slab heat system, heated by a wood burner. I will want to automate some of this system such as relay function to open/close an air intake door, basic programming of on/off of certain functions based on thermocouple inputs, and set delays and "if" statements such as to stop one pump at a set temp but run another until a certain other temp is met.
I know they make basic thermostat controls for this but I would like a variety of inputs and would prefer something software based so I could put this on the network. That might be wishing though because this system is on a budget.
The only real sensor inputs I need is K thermocouples and hall sensor type flow meters.
I will need 5V outputs for the hall sensors as well as a variety of programmable relay outputs.
What am I looking for?
