I have this thermostat that was installed new August 2008. It controls air source trane heat pump and LP gas furnace dual fuel.......the problem is that the left side of the screen has become non-responsive (dead), we can change temps on right side,...

My thermostat touch screen also failed. I replaced the wall maounted unit (not the controller mounted at the furnace) and it now works fine. If you have a high efficiency system with multiple heating/cooling settings, you will need to program the thermostat. I didn't learn this until a later furnace tune up when I was told the system was using only the low load setting. The technician programed the thermostat.

It has only one single terminal for both aux & emerg. A thermostat for 2 stage heat pumps should have separate connections for each. Moreover, there is no good control over swing temp (Emerg to heat pump) and in-house variance. I got one and didn't like it at all. I don't believe it is a good design for 2 stage heat pumps and emailed honeywell and told them. It does keep your house temp very consistent at the expense of using the emg resistant strips when not really needed and over cycling the system.I removed it and installed a Braeburn 2220. I like the Braeburn because it is easy to have control on swing temps and in house variance. Also very easy to change settings. It has only one single terminal for both aux & emerg.

I think I recall seeing that also. But the thermostat is totally digital. I'm not sure if has pilot light I'm not home or I would take a look. I don't recall lighting one and it does everything automatically. I just set the temperature and forget it. This is a great heater.

I am not certain it will still work since I don't know what was the cause for the temp spike. I suggest that you test the function by changing your setpoint and see how it responds. Given the low cost of the unit, I'd not hesitate to replace it if my process is important. Good luck.

I had a Duxtop that worked well for about 13 months, then the thermostat failed. After the nuwave fiasco I tried another brand from Amazon, Burton, and the temps were all over the place. Returned it and got another Duxtop, no where as good as the first. Sometimes thermostat works, at other times 180 = 360. I'll wait till wife wins the lottery and get a commercial unit.

If the batteries are dead the thermostat will not work. However the batteries last a very long time so change them on a yearly basis if you are concerned.

I also replaced my old mercury tilt switch this digital. Just be sure to follow replacement instructions, and write down where the colored wires are attached on the old thermostat. Don't just tag them with the stickers provided. It shouldn't be a problem switching.

This is the second 7619 thermostat we've owned and they both have had a 5 minute delay before the fan would come on! This is for the pump to wet the pads, I know Fan Only doesn't need wet pads, but the circuitry is set up that way. Just be patient, it's working!

Did you slide the system button to "cool" ? Is the breaker for the air conditioning set to "on"? Are all the wires under the thermostat making good contact? If you need more help, I would contact Honeywell. They are pretty helpful.

John,I had the same problem when mine was new. I had to use considerable force to get the battery seated well on the contacts. If you hold the device in both hands and use your thumbs to "rock" the end of the battery, it will seat properly.This has been the most reliable alarm for me. It has contacted me at least once each of the last three winters to let me know that the furnace was not working properly. It has saved me thousands of dollars.

What I have found is if you turn the thermostat all the way up it acts as a constant on. Hope this helps

The thermostat retains the last settings if that is your question. If power is out, your HVAC is out of commission anyway :-)

I think we have the light grey one so I can't answer that question. When the power goes out there are batteries that allow the thermostat to continue to work. However, your furnace/AC will not be working. When the power comes back on the thermostat will re-establish contact with your WiFi and everything will be fine. If you go to the Total Comfort website you can set up an email message to be sent you if the thermostat looses contact with the WiFi. That is almost always because of a power failure. I love that feature as we live in Alaska and spend several months outside of Alaska at a second home in the winter. So I know when the power goes off and it notifies me when the thermostat re-establishes contact with the WiFi when the power comes back on. So if there is a lengthy delay I can call and have someone go and check our home out. Hope this helps.

You may have a wire crossed. My works just as the oem did. I took a picture of the wires before removing the old one and put the wires back on the exact same way. When mine hits temperature setting (either heat or AC) it shuts off automatic.

Hi Sheldon, It was very easy to replace. The directions are clear and easy to follow. Just determine what type of system you, look at the directions and follow. The terminals an the new thermostat are labeled for wire color. There is one "jumper" on the new thermostat that you may or may not need depending on the system you have. I did not need the jumper, so I removed it ... easy peasy.

Try turning the thermostat controller all the way to the right. Otherwise call Vornado customer service, most of the machines have a 2-3 year warranty.
