SOURCE: How do I change the
Try adjusting the heat range up. Set it a 77 then try the cool.
I believe the Honeywells have a max range between cool and heat.
also sometimes there is a lock out code on them you'll need the book.

SOURCE: My furnace cycles too often.
recovery has nothing to do with on off on off. you have a new digital stat that holds an exact to the degree temp a change of a half a degree can bring it on.. so stat needs to be above main return 5 feet off floor. away from any drafts , doors supplys etc. also be sure the hole in the wall is sealed . the cold air in the wall is more than enough to make stat come on . they are incredibly sensitive.an old mercury bulb stat would have a swin g of 3 or 4 degrees . so set at 75 it may heat up to 78 and stay off till temp fell to 73 so you get a longer run cycle or and longer off cycle. the new ones are on off on off keeping a perfect temp 75 exactly. thory is the heat exchanger is already hot and a quick short cycle is more efficient than being off 20 minutes and reheating the heatexchanger from scratch again. having said that if you look aT the installer set up instructions that came with the stat it may give you an option to reset or adjust the stat so it will have a one (default) two, or three degree adjustment , so 75 equals up or down three degrees on call for heat.see honeywell toll free number in their literature

The user manuals don't show all the codes that the thermostat has....
If you can find an installer manual for this thermostat, or a similar one, it will provide the installer-only codes. Search for 69-1894ES.pdf - I think you want code 0530, and set it to 0. You access the installer codes by pressing two buttons - the ones each side of the centre button that you press for the user codes
