T-stat ????

Finally have my EKO 40 up and running self install and need to finish up wiring T-stat to LP furnace. That is where the ? lies. I have 3 zones infloor, garage, and water to air exchanger in LP forced air furnace. I wanted to go with all zone valves but my run to house was farther then I liked 150` so I zoned with pumps

I have a three stage T-stat with a seperate fossil fuel controller for the heat pump ( only using 2 stages heat pump is single stage ) fossil fuel controller also controls LP furnace. The fossil fuel controller has it`s own 24 volt power supply. I allso have a circ pump controller with it`s own 24 volt power source. I want to take my Y1 wire from T-stat on my heat pump controller ( since I won`t be using the heat pump function ) keeping my same T-stat and wire Y1 into my circ controller board, to make my hydronic system my main heat and my LP furnace back up ????

I have some ideas but would appreciate more input. K.I.S.S. method.

I am soley responsible for my own actions taken.... just to C.Y.A.

Thanks Merry X-Mass
Thanks

Y1 controls first stage heating and first stage cooling depending on thermostat position IE heat or cool.. According to my T-stat directions.

I thought of that to keep it simple but I am being stubborn and would like to keep the single stat. It must be the Polish in me. LOL
