Thermostat Question
« on: December 15, 2016, 01:25:44 PM »
Ok, so I bought a house and I have to replace the American Standard thermostat that is broken (touch screen broken).  I'm replacing with a cheap one from the depot.  The old one has the standard r,g,y,o,b on one side and x2,w1,s1,s2 on the other side.  The new thermostat has r,g,y,o,b,w (aux). From what I've researched the s1 and s2 are just outside temp sensors but that leaves me with the x2 (black) and w1 (white).  What are they for? Any multi stage systems I've read about had y2 and such which this one doesn't have.  Btw this is a propane heat pump system

Heat pump systems require a different type of thermostat than a normal HVAC system. Either get a proper thermostat and carefully read the instructions, or just pay a professional to replace it.

Yea the new thermostat is compatible with heat pumps with electric backup.  My other house has a heat pump and not the extra wires I'm asking the question about
