Hey there… Went to install my wzye thermostat into a hydro (Water sourced) heat pump and is says the wires there are not compatable… I know some wires serve different purposes so I figured I would ask here if there is anything I can try?
Pick of the back of my existing thermostat is attached.
Thanks
Ray
Also, if you are trying to contact speedie, you need an @ symbol in front of the name, and for that to be placed in the body of a message.
You also would likely need a photo of the other ends of those wires at the control board on the furnace. 
It should be fine with these wires. Red is Rc, Yellow is Y, Green is G, Blue is O/B.
You’ll need the C adapter, unless you have an extra wire in the wall.
