Question about Honeywell Electronic Programmable Heat/Cool Thermostat - CT3300A100 Heater

1 Answer

Same problem, backlight on all the time

Just had BGE (local power company) install the UtilityPro thermostat that allows them to cycle the compressor off during peak electricity usage in exchange for some monthly savings on the bill. This thermostat replaced a Honeywell VisionPro thermostat which looks identical. The VisionPro backlight automatically turned off after the screen was not touched for a few seconds. This UtilityPro model just goes slightly dimmer instead of off. Not really fond of the green glow on the wall all the time. Nothing in the manual on how to change the backlight setting. There is a USB port on the side. I'd like to find some software that can recognize and reprogram these hidden functions. Plugging the USB port into my laptop just results in it loading an "unrecognized device" A search of the Honeywell website so far has not turned up any programming software.

DOMETIC DUOTHERM KICKS THE BREAKER MAY RUN FOR A DAY OR MAY RUN FOR 8 HOURS BEFORE IT DOES IT IN MILD OR HOT WEATHER. ALREADY REPLACED BREAKER AND MADE SURE WIRES ARE TIGHTNED. HELP PLEASE.


If all appears OK, no noise, good cooling suggest check thermostat. If the thermostat is allowing the compressor to short cycle, restart under load the breaker would be expected to blow do to overloading the compressor.

There is usually a 5 minute time delay in the thermostat that prevents this.

the compressor is supposed to cycle as it is controlled by a thermostat
if the cycle times are too short then check the following
door seals in good condition --cracked or broken seals let the cold air out
thermostat setting too cold -- doesn't allow for a long period to warm up
door being opened too often motor stops then has to restart from the door open
problem thermostat

Intertherm Air Conditioner S3BA-042KA compressor and fan not working (has power)


It sounds like that unit is connected to a "power saving load controller" device from the power company. The power company can turn your unit on & off with a radio signal. If you manually activated contactor and unit ran. I would bet that the power company's device or the wiring connecting it is where the problem lies. Call the power company and have them check their device. If they tell you that the device has been tested remotely and is working fine. Explain to them that you can activate your unit manually and it works fine. They should not charge you to come out. Those "load controller devices" have a pretty good longevity record.

Compressor for air will not cycle on.


Check and see if you have a common wire on the thermostat. If you do not, then you will need to replace batteries if applicable.

If you do have a common wire, then batteries are not necessary for thermostat operation.

Even though the thermostat wires are secured properly and the thermostat worked fine in the heat mode, it doesn't mean it will work for the AC mode.

If you want to check the thermostat in an easy manner, you will need to jump out the Red and Yellow terminals at the thermostat. Be sure to turn off power first to the furnace. After jumping out, restore power to furnace. If the unit comes on, then your thermostat is bad. If the unit fails to come on, you have another issue. You can repeat this process at the outdoor unit with the low voltage lines if you feel capable. If unit comes on, your problem lies between thermostat and outdoor unit. If your unit fails to start, your problem lies within the outdoor unit.

Be sure to check any drain pans, float switches, or cut-out safeties installed that may cause this. Many contractors will wire in drain safeties to the outdoor unit to shut down the compressor in the event a drain line has clogged and backed up into the emergency pan. Of a condensate pump has failed.


If you do not feel you are capable of this, you may need to contact a local professional to come diagnose the situation. But those are a few simple tasks that you can complete yourself to narrow down a problem.

Honeywell UtilityPRO thermostat backlight won't go off


After posting that I was having the same problem, I found a solution.
I used these instructions http://www.hydro-temp.com/help/drawings/honeywell%2069-1894ES.pdf and followed the Installer Setup on pages 6 through 10. Basically you just need to enter the setup mode following the instructions, scroll to setting# 280 and change the setting from "1" to "0" then the backlight will turn off after 8 seconds. Don't change any other settings if you don't know what you are doing.

Air condition problem


What type of thermostat do you have? If the fan is not coming on and neither is the compressor, then is more than likely a problem with the thermostat of control units of the Air Conditioners. The fan will come whether the compressor does or not if the thermostat and control unit are working correctly. Check for twelve volt at the control unit of the air conditioner ceiling unit. (Red Wire, should be labeled)

Outside Unit blowing air but not cooling and slight buzzing sound


The compressor is not coming on and some part of that unit has failed. Do you hear any clicking sounds along with the buzzing sound? Recommend that you shut the unit down (remove power from it) until a service tech can listen to it try to start up.

The power company-installed load management system is probably a red hearing. That system will either fully turn off the unit or allow it to turn on/start up.

Compressor short cycling


If the compressor is run off of a relay then you could install a delay timer to prevent short cycling.
