I came online to update my post and found your reply. Thanks for your response. I'm not using batteries with my thermostat and the purpose for the I/O module is to turn on an additional wall heater when the main heater is on. The I/O module was working beautifully with the old Insteon thermostat, so I gave it a try. The update I came online to make was that I found the culprit. I assumed there was something in the thermostat that was causing the premature command to off. Among other features, what the Go Control thermostat does that the Insteon thermostat doesn't do, is report a change in temperature measurement with each degree. I had a secondary program that used an else statement and in the if statement, I had, If temperature >75 degrees and the wall heater was on to turn off the I/O module. Since the Z-wave sends a temperature our with each change, the else statement picked it up, since it was under 75 degrees and shut off the I/O Module. The Insteon Thermostat wouldn't trigger it for being under 75 degrees. It was a bad program and I have deleted it and found a better way to prevent using the wall heater when it's above 75 degrees.
Thanks, again.
