When the temperature drops below 5 degrees outside, the unit display powers on and off intermittently. Any ideas, because its really annoying.

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.

That hasn't happened to me, but I assume it's either something wrong with the display unit, which has all the circuitry behind it, or there is something wrong with the wiring that's going out to the external sensor. Check to see the wiring and connections at both ends are good to rule out the easy fix of just reconnecting everything well.

I have found that the unit will automatically restart, but it will not save your settings. You will need to re-program F/C and the temperature after a power interruption. I have been pretty happy with our unit thus far. -DA

I had the same problem but I finally discovered the cause. I had one of the lights close to the sensor on the unit. When the light was off, everything was dark and the light came on. After a short while the unit sensed light and shut off.

It shuts off then start up again when it reaches a certain heat, but you can't read the actual temperature.

As I recall, the display turned off after a short time period. However, I never did get the device to work properly, so I can't go back and check at this point.

It has to be on both legs of the power. Try locating the display as close to the unit as possible. Turning the power off to the unit on the line will reset it, I believe.

I'm in WI (we had frigid temps this month!) and it has been running fine for us. We set ours at 72* and it stops running at about 72-73. Yours may be defective?

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.

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.

The current temp should always be displayed. Mine sometimes goes blank and shuts the furnace off. I believe it to be caused by poor solder joints at the connector. I have not attempted to repair it yet.

Take the battery out of the thermometer and re-install it install a new battery. If it doesn't clear the problem, get a replacement.

My temp lcd turns on and shows temp while water is on only. Had mine for 2 yrs now and havent had a problem. The button below my lcd never did anything - not sure if it was ever suppose to have a function.

The top button is your answer, sounds like it might be faulty. I'm sure you've already tried to just take it out and unplug it and let it sit an hour or so then 1) put it back in the water for 20-30 minutes, 2) plug it in and set the temp. I love mine - and 78 works for my Beta but it will cycle through the choices just fine. I like the way it blinks at a different temp to show actual water temperature.

The digital display does go inactive after about 4-5 seconds. Meaning it will go away after it has been set to desired temperature.Carlos

It is my understanding that it is supposed to be set then it turns off once it reaches said temp. Then when it drops it turns back on. This model I bought did not. I'm sorry about the vauge answer. I was just disappointed with the initial faults, I had to send it back.

I don't know, but mine stopped working when temps got below 0 outside recently
