Hi. Sorry that you're having issues. Here's a crazy question. Have you reinstalled the original thermostat (or a basic non Insteon thermostat) to the same terminals to establish/deduction if the 2441TH thermostat is out to lunch? If you don't have another thermostat, you can check out the YouTube video below. I'm not sure exactly where things stand on your end so here goes. Like the guy in the video says, you can even do it at the thermostat... This should tell you if your 2441TH has some sort of fault. I own 4 of that exact model and I have never had crazy issues like what you're up against. I don't recall reading if your furnace actually works which is why I'm posting this. Sorry if this might have nothing to do with the price of eggs. (Your connections to the 2441TH look fine from what I see. As for the image with the Cool 30 and Heat 20 both showing at the same time on the display - that's some funky stuff). I also would make sure that I don't have a Program sending conflicting info to the thermostat. Also, I googled this for you (I have never had to do this mind you): To change the temperature on an Insteon thermostat to Fahrenheit, you can calibrate the thermostat as follows: Press and hold the Program button until the display goes blank • Tap Time/Sensor to enter Temperature Calibration Mode • Tap Mode to cycle between temperature and humidity calibration • Use the Up or Down arrows to adjust the temperature until it matches the calibrated source Last but not least, in EISY you will get 3 things... Thermostat Main Thermostat Cool Ctl Thermostat Heat Ctl

@dbwarner5 Hi, Yes things are communicating as they should - However, Heat - Ctl Status still shows nothing. It used to say Cooling On before I reset things. Ultimately there is frost on the ground outside and we have heat :-). When settings are changed on the TH (which is Master) settings after a short moment get changed on the ZTH which it is supposed to do. Cheers

I did Factory reset on 2441TH. The TH did everything that it was supposed to do - and it reset. I then disabled the other ZTH thermostat so it wouldn't communicate with that TH. Here's where things stand: Mode = Heat. The furnace is heating and working like before. However, the difference now is the Heat/State = Idle after a Query on the TH. The problem is that it not in Idle. The furnace is heating. At least it isn't saying that it's cooling in the Heat/State box :-). Hmmmm The Admin Console also for the TH says: Cool Ctl = Off Heat Ctl = Off As mentioned... it's heating... I might try deleting things and starting over. I just wanted to post my findings.

@dbwarner5 I will certainly try what you said. I followed the manual to set up the ZTH's. As mentioned, Master wouldn't work back and forth if they weren't talking with each other which they seem to do. I am able to control the TH with the ZTH for that particular furnace. I cannot stress this enough how I appreciate the help.

Hi everybody. Thanks for your reply. Please let me fiddle some more and I will post my findings. To clarify: Two furnaces wired directly with two 2441TH (one for each furnace) the way it always was for 10 years before upgrade to EISY. I recently purchased two (2) ZTH versions and one is used for one furnace and one is used for the other furnace. I have the ZTH's hooked up to monitor a different room. If I hold the Master button on the ZTH, it will be set master. If I hold the TH as Master, then that one becomes Master. Therefore the ZTH's are behaving like they should according to me otherwise they wouldn't be synced. Even if I disable the ZTH's, I still have the issue. Short of deleting things and starting over... that's most likely my next route to take. Cheers

Hi, Thanks for the reply. I put one 2441TH in linking mode and did the restore device. The 2441TH remained with a large 1 and it said Cooling after the restore. I had to press the Set button to exit after restore was done. In other words, nothing changed. I increased the temperature and it still says Heat/State = Cooling, Mode = Heat. Not sure... hmmmm... I would also like to say that when I turn down the heat on the thermostat to match the temperature of the room, the Heat/State = Idle, Mode = Heat. So Idle is good... but when I put the heat back up it repeats the problem.

Hi all. This is my first post after using ISY994 since 2014 or so. I just upgraded to EISY (new) using 2413U (new). I had no problems implementing the new setup. I do find the new 2413U seems to be way more stable than the old 2413S that I had purchased 10 years ago. No comparison. Firmware: IoX v.5.8.4 UI: IoX v.5.8.4 However, I now have an issue I am unable to solve it seems. The Heat/Cool state is showing that when Mode = Heat, the Heat/Cool state shows Cooling. It shows the same in the UD Mobile app and the Admin Console. The thermostats are 2441TH. I have 2 furnaces (I cannot stress enough that this only happened after EISY upgrade). BOTH thermostats for the furnaces are now responding in the same way. The thermostat shows Heating (which is correct and fine) and not Cooling when you increase temperature to kick on the furnace. The furnace works as it should. I know both of these furnaces inside out and nothing has changed regarding wiring to the thermostats. When HEATING, If I select the Cool Ctl, it shows Status On. The Heat Ctl also shows Status On. That's a real first (when Cool Ctl should be OFF). I can assure you that I feel I have tried everything. Restore PLM. Restore Device. Nothing helps. If anybody knows where I have obviously done something wrong, then please do share. The only thing different now is that I created a Scene with a 2441ZTH wireless version (which is actually powered with 5V) to each of the 2441TH's (two furnaces therefore two 2441TH's each with wireless ZTH - just to be clear). Switching back and forth with Master works on the ZTH with the TH. I also have the correct time on the 2441ZTH. Cheers
