I have a Totaline 1-day thermostat and an Insteon 2441V for about a year now.  The last couple of weeks I'm seeing random heat on/off events that last only 2 minutes.  The short time is because the setpoint minus dead band hasn't been met.  So what is possibly causing this odd behavior: ISY994i, Thermostat, Insteon 2441V, PLM, RF noise?

 

I copied the logfile below of the last event which just happened tonight and seems to happen at least once a day.  I tried resetting the thermostat and also moved to v4.4.1 firmware but neither changed fixed anything.

 

ISY994i Firmware v4.4.1

Insteon: 2441V Firmware v2.5

Hi Jrissmill69,

 

This very much sounds like the thermostat itself. Is it possible to change the dead band configuration to 3 degrees (temporarily) and see if that works? If not, then I would suggest contacting Venstar.

 

With kind regards,

Michel

Michel,

Thank you.  I will give it a try.
