My thermostat stops cycling at night... It shows 72F with actual 80F. Works fine during the day. Replacing didn't help. Any ideas? (Swing is 1.)

maybe try resetting it to factory settings and try again. Maybe remove battery?

Not totally sure But it's possible you activated the Autoprogram feature. Tried resetting it?

To ensure the temperatures are nearly the same, make sure you place all comparing thermostats in the same exact location. Even testing across the room can make a difference, possibly what you are experiencing.

I got this for my trailer. The old thermostat had a large swing (ie) swing is when the thermostat is set for example at 70 degrees, but the thermostat doesn't turn on until the temp falls lower than 70. So a large swing a thermostat may not turn on until for example 67 degrees, then turns off at 73 degrees, hence a large swing. This thermostat has a low swing. You don't get cold before it turns on, and it turns off before you get hot. In other words it keeps the temp very close to what you set it at. Maybe a 1/2 degree swing. YES - when you raise the temp it will turn on.

Mine recently started doing the same thing, after working great for a couple years. Opened it up & found the thermostat had disintegrated. Turn it upside down (not plugged in!!!) and listen for objects rolling around. If so, your thermostat has likely died too. There's no good fix, other than bypassing the thermostat - which is a home-fire hazard. Sorry, you'll probably have to trash it (unless it's still under warranty)

That is normal. The thermostat turns it off when it reaches temp. There is also a high temp switch for saftey.

My heater does the same.I had two since the first broke. I think their thermostats just dont work well.

Flashing lights mean that it is heating. 78 is preset at the factory. Use the up arrow or plus button to increase the temperature. 78 is too cold for most climates. I run mine at 80 in summer and about 82 in winter but I like a cooler bed. Also to minimize the amount of heating, put a thick blanket or comforter across the entire bed to avoid heat loss.

Mine did the same thing but soon stopped. I use mine for night lights in the house and they are on from dusk to dawn. They even run cooler now than they used to. Maybe it's a break in thing?

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.

Hi,Mine first did that when it was first installed. The temp was set to high. I unplugged the unit and not turn it back on until the next morning and it has been great since then.

Just make sure you set the new one to the correct time zone. Its buried somewhere in the Honeywell software options. Mine reset to the incorrect time as well (after I manually reset the time.) I'm in AZ and the daylight savings option was throwing everything off.

I now like the machine but the settings/temps process is mysterious. In brief, be sure it is in the mode you want; like standard and not eco or fan. I turn it on and up to where it starts, then back it down. I set its reading to four or five degrees higher than I actually intend. This way it cycles on and off at night and keeps the (bed)room at the desired temperature. This advice may not help. In which case persist; just fool with the thing until you win. Or call LeLonghi and good luck with that.

Either the thermostat is set to low or it may be defective. Also the heater needs some outside air or it will shut off. Good Luck!!

I have no idea what is going on. I have two of these units, and it is -1F outside right now, and both are reading normally. I think you may have a defective outside sensor, and should contact Honeywell.

You say 24/7 so than set all (Morning, Day, afternoon, evening to 79 degrees). for weekdays as well as week ends. I believe the unit is set at 1 degree swing. So when the temperature reaches 80 the ac will turn on. You can change the swing degrees on this unit. You can download the manual from the Lux Web site. Don't forget this unit will only work with units that come on after power is turned off. So if you ac unit is on and you pull the plug and than when you plug it back inif the ac comes on without you having to press any buttons than this unit will work.

Don't know if this will help but before you installed did you lay it in full sun for the day so it was sure to get a full charge? I am assuming you installed in a sunny location. If "yes" to these it sounds like it is defective. Return or exchange it. My mom's has been up for over two years in a partially sunny location is is still working. Good luck.

same thing happen to me, I got a new part for the heater it kept doing the same thing, so I just stop using it, because it will go out at night an you will wake up cold, I think it is a bad heater.
