Is this set up like I think it is? Ready to plug in the thermostat to the back of the stove? Based on what I'm seeing (see pics), it's a little different than the M55. Those red/black wires running out of the blue connectors in the upper right corner, run into the back side of that plug in the second pic. And if I'm right about that, my next question is, does it matter which wire goes into which side of the plug? Not much direction in this manual, and I know next to nothing about HVAC and electrical stuff.
