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

1 Answer

Cooling Problems I just purchased a 3 bedroom one level condo. I have a Hunter programmable thermostat 44250. Not sure of the type unit I have. The air handler is in a storage closet outside. I noticed the other day that when I set my thermostat to 73 degrees it was at 80 degrees inside. The unit ran constantly for 4 hours and only got down to 78 degrees. I called an hvac company and they came out yesterday. They cleaned the coils, flushed condensor, flushed drain and line. Checked pressures and temperature differentials and added 2 lbs of r-22. Also installed new valve caps. Last night it cooled down just "ok". It took 5 hours for it to go from 78 degrees to 73 degrees. Now today, I turned the thermostat down to 73 degrees and it was 78 degrees. Here it is 3 hours later and it is only down to 77 degrees. I live in Upper State South Carolina and the temperature outside ranges aroung 80 degrees. What I don't understand is that I can sit five feet under the vent in the living room and can feel the air really good and it is cool air. But in all the other rooms, I have to get a step ladder, climb up it and put my hand one foot from it to actually feel the air. I don't know whether the tech checked the vents are not. Here's what puzzles me, the best flowing vent is in the living room where the thermostat is located. Why isn't it cooling down the thermostat? What is the problem? The unit is about 8 years old and the compressor was replaced last summer. It always stays at 77 degrees and runs and runs and runs and only decreases one degree.

Your filter is clogged. Not the one at the bottom of the unit.The one above the unit. It is like a raditor coils, kind of a bear to get to. We have cats and dogs the filter gets most of the hair but not all.Usualy about 6 bolts to take out.The proublem will be at the bottom of the top filter.

Why won't thermostat turn on after I changed the batteries?




I think you may have the model # incorrect, However if you have a thermostat as in the type that are hand held, polarity of the batteries is the 1st thing I would check, then test them for proper voltage, corrosion will often interrupt that small of a voltage, clean the terminals and test it .




A wall mounted like a central HVAC system typically will not require batteries to operate, this is for memory and they will work fine even if no batteries are installed, however there are battery powered stats too, meaning non parasitic type that not powered by the transformer in the air handler.
I will include a basic drawing of a residential HVAC thermostat to show you how the 24 volts powers most thermostats.

What do i do. Im getting 230 volts to unit. Not getting the power light to come on .. the display doesnot appear.


Not sure what power light you are talking about, or what type of HVAC system you have. Though you say that the display does not appear. Is the display on a programmable thermostat? If so, most programmable thermostats use an internal battery for power and not the low voltage side of the air handler. So check your thermostat to see if it does take a battery(s) and try changing them.

I have a Trane heat pump, model #TWP060C300A and a Trane air handler, model #TWE065E130A. Heat pump is 5.0 ton, split system. Air handler has a variable speed motor and a 20Kw 3-phase auxiliary heat strip....


Honeywell Chronotherm thermostats have always had a great reputation for longevity and reliability. They are also much more user-friendly than the other types of programmable thermostats out there. Make sure you get one that states 2-stage heat, heat pump. T8611G will offer that for you. There are many out there that claim to be suitable for heat pumps; however, they do not have the ability to utilize your auxiliary heat strips (2nd stage of heat).
Before you attempt to replace, be sure to write the wire colors and their corresponding terminal marking on a sheet of paper........of your old thermostat. This is very important to make it easier to hook up the new thermostat. Also, before you disconnect the wires, be sure to shut off the circuit breaker to your air handling unit. You can ensure you have the right one by putting the fan switch in "ON". When you turn off the right breaker, the fan will stop running. :-)

I hope you find this information to be very helpful to you. Please don't forget to leave a rating.

Hunter 44630 thermostat


Here is a link that will have wiring diagram it is for a similar model hunter. Also check your dip switch on the back of the stat to ensure it is set for gas (HG) or electric heat (HE) depending on your type of unit. Good Luck. Rule of thumb for most four wire systems is RED (power to stat) Yellow (Cooling) Green (Fan) White (heat)
