240 between hot and neutral?

[jdub2]

I have a thermostat that just stopped working a few days ago. This is what voltages I'm getting:

Hot1->Hot2: 44
Hot1->Neutral: 243
Hot1->Ground: 121
Hot2->Neutral: 10
Hot2->Ground: 16
Neutral->Ground:122

There is another thermostat on the same circuit (on opposite side of wall) that is working fine and I'm getting 240 between hot and hot.

Connections in the junction box seem good. Nothing really has changed in our house recently that I can think of. The wiring is in an internal wall. What should I look for next?
