Not sure where it is showing lo and under what conditions, without digging up the manual and going thru it my initial guess would be lo is Low Battery. Try changing them and see if it goes away.

If the heat pump is working and you can turn it off and on and also use the a/c, then the trouble is probably just the display on the thermostat, not the action of the thermostat. You can live without the word being displayed. A new thermostat is easy to install and cost about $100 through Amazon. On the other hand if heat is coming out when you are trying to use the a/c, the heat pump is not working correctly and you will need a qualified service technician.

I believe so, check with your installer because this unit comes with two components,1: is the thermostat itself, 2: is a unit that connects at the furnace or AC unit.

Was the unit installed by you or an air conditioner professional? Did you do the wiring or have and electrician do the wiring? I would call the person (s) who did the installation and report the problem, if you installed I would recommend calling in the experts. There could be serious issues with the installation if not done properly and you don't want an electrical short. If it's the unit call Amazon.

This is also what I need to know...I have the same junk thermostat I figured this should be a nice upgrade one way or the other its going in....It's a shame you cant find decent instructions, as many people that buy thermostats you'd think that they would have a ton of instructions/upgrading info etc...

If the unit is still running after it has met the desired temp that it has been set to then you may need to exchange the unit. I would call technical support for further details for troubleshooting options.

Sorry, I have no idea what you are talking about. The AC is excellent - no problems whatsoever - does a great cooling job.

Could be a bad unit or it was installed wrong, contact the company and report it, you may be Compensated for it!!

I think they have the description wrong, I googled 80 series blue and it is a different thermostat, also my new thermostat is b@w display!The thermostat that I replaced had different wiring though, it was the same but it did have an extra jumper wire, I had to study it for awhile to figure it out but it worked when I hooked it up, my old one was like 20 years old so I think they upgraded it!

I think the auto thermostat just speeds up the fan when under load. I wouldn't worry about it.

It is very normal; my electrician explained it to me when he installed the thermostat - nothing to worry about! Donna

It's an a/f sensor. It is new, and I have used these before, and they work good. You have to check your car to see if it is California or Federal emissions. It makes a difference.

More information is neededsuch as what system do you have. Is it just a furnace or does it incorporate central air. And what connections were on the old thermostat (w,r,y,g)?

I don't know what that means. I bought this product and had installed by a buddy working on my house. Haven't had any problems.

Hello Julia... it is. This is a power saving feature. The AC gears up until it reaches your desired temperature and it gears down to save energy. After the cool down it gears up again to regain the temperature. Greetings.

There could be a couple of reasons. Either the arm is not turning or the seal is off, not allowing a proper seal. The last possibility which is beyond my expertise is the thermostat may not be working properly. Hope this helps.

I had an a/c tech check and then charge the system. It was not precharged.Good Luck
