T-stat ????

[Bricks]

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

Isn't Y1 first stage cooling on your thermostat?

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

in the interest of keeping it simple we just wired a separate thermostat for the boiler and turned the gas thermo down to 67 so if the house cools down the gas will take over.

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

One option might just be to add an aquastat to the EKO (or possibly use it's internal controls) and use that to drive a relay that sends the heat call signal to the wood side if it's hot, and the fossil side if it isn't...
