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.

well lets start with the 2" pvc pipe. that is a combustion air intake it does not put air into the room, i hope. this is a 90% furnace and they should have installed it that way. there should be 2 pipes to the outside the other is combustion gases. the dust problem maybe caused by the air return pulling the air to that room. the bedroom normaly does not get the trafic that the rest of the condo does.so it would not have as much dust.

AC unit goes on and off every 3 minutes


It should not be doing that. The thermostat is pre-programed for only 4 cooling cycles per hour. You can change the program by :
�� To access the configuration menu, press both up/down buttons
simultaneously for 3 seconds.
�� To go to the next parameter (menu item), briefly press both
buttons simultaneously.
�� To modify a parameter, press one of the buttons.
�� Repeat steps 2 and 3 if necessary.
�� Press both buttons simultaneously for 3 seconds to exit
the configuration menu.

You are looking fpr parameter CPH this number tells the unit how many time per hour to come on lower it to leghten the time betwen cycles.

i would have to say replace the t-stat. did they change the filter. did they check the evap coil. did they clean the condenser coil. your supply temp should be at least 20 deg colder then your return temp. do you have an attic fan and is it working. is your unit over 15 years old the consider a system replacement. is the unit sized correct. every 400 sq foot of house you should have a ton of cooling. also can you feel drafts at your windows. all thing why your house could be warm. also check your ticket and see what your super heat was it should be 9-12 hope this helps.

Programmable thermostat not working. Does not


First you must determine if it is thermostat or unit being controlled.

See if "fan" switch will start fan when switched to "on". If not , remove top section of thermostat and short the R terminal to the G terminal. If fan starts, the stat is bad and must be replaced. If fan does not start, the issue is with heating/cooling unit.

On some programmable thermostats you need to hold either the up and down buttons together to get
the thermostat to stay on farenheight.

It could also be that you will have to go in the program and make sure you set it to farenhieght.
On the back of some T-stat covers it will explain how to do this

I am installing a Honeywell T841 onto existing RGYW wiring. The fan kicks on, but I notice the air conditioner is not running. Were one or more of these supposed to go on the W2 or B terminals? Thanks!


Need to have more numbers in model number to be sure There's about 30 T841 t'stats and some are1, 2, and 3 stage heat pump and some 1, 2, and 3stage AC.
If you have
R to transformer
G to fan relay
Y to contactor in outdoor unit
W to Gas valve
You have the thermostat wired right.
Depending on the T'stat B could be the common side of the transformer or 2nd stage heat.
W2 terminal are for 2nd stage heat
You need to put the thermostat on cool and lower the setting to bring on the cooling. Then go outside and see if you have power to the outdoor unit and 24 volts to the contactor coil.

Honeywell Thermostat


Make sure G from indoor unit goes to G on thermostat for fan continous fan, if that doesn't work and you have 24 volts to R and C then the t'stat is bad.
For 2nd stage heat or aux.heat, on the indoor unit you need to make sure the wire W2 from the indoor unit goes to W2 on t'stat.
You don't need any wires from W1on the indoor unit to W1 at the t'stat because with a York heat pump Y1 is the contactor which turns the compressor on and you will get 1st stage heat, and for cooling the t'stat will also bring on O which is the (reversing valve) or cooling changeover relay for the cooling mode.
C = common usually black wire
R = hot usually red wire
Y or Y1 = contactor
W1 = 1st stage heat not needed for heat pump
W2 = Aux. heat indoor heat
G = fan
O = Cooling changeover relay
B = Heating changeover relay
L = System monitor
E = Emergency heat relay
