bh56 Posted November 18, 2014 Share Posted November 18, 2014 I have a 2441TH. Periodically the Thermostat switches into the Economy Mode. The leaf button. This changes the temperature about 4 degrees colder. Some type of offset. I've contacted Insteon and told them that I am using ISY Device. They said that that is the variable and it it possible for the ISY to send a command that could trigger the Economy Mode. and suggested I contact Universal Devices. Wondering if anyone else has experienced this issue and knows what causes this situation? I'm on the 4.05 version. Plan to upgrade to the latest, but currently traveling and will do when I return.

Xathros Posted November 18, 2014 Share Posted November 18, 2014 Hi bh56- Its not the ISY. More than likely, its the 2441TH not being able to handle a spike coming from your HVAC equipment. Assuming its your furnace based on the time of year. Some with gas fired furnaces have reported this as a result of a spike sent when the furnace either fires or shuts down. There are a number of threads on here about this very issue and some of the steps that have been taken to try and remedy the situation. I don't recall if there was ever a final accepted solution however. Personally, I think some form of OptoIsolator between the stat and the HVAC equipment is the way to go. Here is a link to one of the threads on this: http://forum.universal-devices.com/topic/9105-a-new-2441th-issue/?do=findComment&comment=72648 Hope this helps. -Xathros Link to comment
bh56 Posted November 18, 2014 Author Share Posted November 18, 2014 Xathros, Thanks so much for pointing me in this direction. I will look at this thread further and see if I can diagnose as it appear that some may have done so. Not sure if there is a conclusion either. But maybe help me in finding a solution.

pgershon Posted December 14, 2014 Share Posted December 14, 2014 I can tell you I have just solved this problem with an APC surge protector. Happy to help. My system finally stops going into Energy Mode after 3 winters with this issue. Link to comment
paulbates Posted December 15, 2014 Share Posted December 15, 2014 To back up what others have said, it's not the isy. I had this issue with 2441TH before owning an isy. Link to comment
