OPs Atwood model uses ONE set of t-stat/ECO for both electric & propane
Design change by Atwood in 2004 so all functions where controlled by circuit bd vs separate control systems.
2nd set of t-stat & ECO would need a complete design change due to the DC circuit and circuit bd controls

I noted in your diagram that propane and electric temps are controlled via the same circuit. That's why I had the idea about adding a second stat. But as you just stated, I did forget about the red wire having the ECO,,, that when tripped, would cause the operator to have to do a manual reset. My idea would not work because a thermostat wired into the red wire would have the same effect.
I initially had the thought that a flow or pressure switch would cause the propane valve to open and close more frequently than desired and therefore not provide the results the OP is after.
Linear Mode
