Hi all I am wondering if I can wire a thermostat with a infloor sensor and an thermostat with just an air sensor together? I Want to put the floor sensor thermostat in my basement( it will read the upstairs radiant floor) and keep my original air thermostat where is currently located. The reason being is my air thermostat is in the kitchen and when we cook the temp in the house(only 1k sq feet) will heat up and then the floor gets cold so then as the temp drops outside I am turning the heat up to get the floor warming then I have to turn the heat down to normal as the the night goes on. I am hoping with both a floor sensor and air thermostat wired together I can elevate that issue. Due to my house layout I cannot put the floor sensor thermostat up staires. My new uponor 501S is half the size of my current one and my house is all knotty pine and there will be a noticeable light mark around the 501S if I install it and the wife don't like it.

Maybe you should switch to just the floor thermostat...
