This is the second time this thermostat has gone zombie on me. The last time, it recovered on it's own.
This thermostat is in a vacation home, and I'm 2000 miles away. I can't afford to have the house freeze. The thermostat is one of the closer Zwave devices to the panel, so I don't think it's an RF issue. How do I diagnose the problem? Are there known reliability issues with this Tstat? Are other products more reliable?
