I have an Insteon 2441TH installed. Been working fine for the past year. The past week, it has shut down twice.

 

This is what I see in the log. What caused it to shut itself down? Nothing programming is doing it. What do the error codes mean? Why did it set the set points at 60 and 80 at 3:37am?  I have no program that does it.

Hi miataguy,

 

What do you mean by shut down? Does it mean that the thermostat turns off completely? How do you get it to work again?

 

The errors mean that ISY cannot communicate with the thermostat.

 

With kind regards,

Michel

Wanted to circle back on this since I finally found the problem. There was a moisture sensor in the air handler that was triggering and shutting off power to the thermostat. I replaced the moisture sensor with a float switch. 

 

Problem solved.

Hi miataguy,

 

Thanks so very much for the update!

 

With kind regards,

Michel
