RTH6300B Honeywell Thermostat

I am having the same issue. My husband installed the thermostat last November and took us a little to get the heating on, but it finally worked. Now that the weather is nice, we went to put the air on, and only warm air is coming out. I called Honeywell, and spoke with someone who had me go in a swith the cool setting, but it still is warm air. My husband checked the wires which are also, GYRB with a jumper between the R and Rc. Any ideas what else we can do?

Honeywell thermostat RTH6300b will not shut off at


I had this same problem with my 6300B thermostat. I did not see this when I installed the tstat and did setup for it the first time. If you go to page 16 of the install guide, there are instructions for setting up your tstat for your furnace and AC. The setting I had wrong was on page 20 of the guide. It defaults to a setting for a furnace/ac that is less than 90% efficient. When I changed the setting to a furnace that is more than 90% efficient, the fan not turning on or off problem went away. The setting on page 20 should be set to "3" if you have a more than 90% efficient furnace/ac. Hope this helps your problem

Honeywell RTH6300B to replace Trane Baystat 239


Sad to say but you have bought an non compatible thermostat, what you need is a thermostat that has "Heat Pump" somewhere on the package, Honeywell makes those also in the same models, sometimes they can be tricky if your not looking. It should also say 2heat, 1cool too. Hope this helps and good luck!

Forced Hot Air Heating system doesn't maintain thermostat setting


It sounds like you may have issues with the furnace. A qualified professional can go over the system and the house to let you know if the system and unit are properly sized. The poor performance of a furnace can be a sign of carbon buildup in the furnace.
Good luck, hope this helps.

Thermostat back light problem.


You need the installation manual which can be downloaded at
http://yourhome.honeywell.com/Consumer/Cultures/en-US/Products/Thermostats

go to setting 280 which sets the backlight options and select option 0 which turns on the backlight for 8 seconds when a button is pushed and then turns off.

This info is not in the owners manual, only the installation manual.

RTH6300B - Not blowing the hot air


I currently have a 2 wire system. I have one red and one white. I hooked the red to the R and the white to the W. I had to go into the system setup using the UP arrow button and the FAN button. The first setting is the 1 setting, and I selected number 2 ( Heating Only ). Then the 5 setting. I selected number 1 ( Gas/oil steam or gravity system ). Then 14 is usually 0 for Fahrenheit. I was just messing around and that is the buttons I used and I tested it. The furnace kicked on and then 10 to 15 secs later the air began to blow through the vents. I hope this works for others who read this.

Honeywell 5+2 day programmable thermostat will keep heating to 29 degrees!


Is sounds like you wired it correctly, The black is a little unusual perhaps its blue, anyway, try disconnecting the wires from the thermostat and see if it shuts off. If so, then it may need to re calibrated. I will need some more info to help you anymore.
