Heating Temperture Range

I have a Honeywell RTH7500 thermostat that I would like to be able to adjust the heating range. Right now the thermostat is set to 68. The thermostat calls for heat at 68 and shuts off heat at 68 degrees. The heat range is within the 1 degree. I want and need to set a range of two or three degrees so the thermostat would call for heat at 68 degrees, heat the room to 70 degrees then shut off the heat, like an old style mechanical thermostat operates.

Can this be done with the RTH7500??? Is there a trick to alter the temp sensor?? If not, is there a programable thermostat that can be adjusted to meet my needs???

I fully understand the comfort of the constant one degree range of the RTH7500 but the furnance kicks off and on way tooooo much. Never even gets things heated up much and the fan still blowing at the end of the heat cycle blows in cooler air which isn't comfortable.

I took a quick look at the manual at:

instructionsmanuals.com/u2/pdf/termostato/Honeywell-RTH7000-fr.pdf. (copy & paste in your browser)

It does not appear to have the ability to do what you want.

If you have a manual for your furnace, there might be an adjustment for the length of time the fan runs after the heat call ends. This might eliminate the cold feeling.

If your heat is cycling frequently, it may indicate that you have an oversized unit or possibly a leaky house.

Yeah, the manuel doesn't say anything about adjusting the heating degree range. Even called Honeywell tech support and they said it was not adjustable. He didn't seem to know much actually, took awhile for him to understand what I was needing.

Can anyone recommend a programmable thermostat that would allow the heating degree range to be adjusted????

Would insulating the temp sensor on the thermostate cause it to delay heating up and cooling down?????

Furnance is sized right and it is a new house. The weather isn't cold yet and so I guess it is oversized for now....come January it'll be just right.

Over the last 40 years, I've owned 2 homes and changed the $10 thermostats with programmable ones from Sears.

They both had settings to lengthen or shorten the heating/cooling cycles.

If you have a one heat/one cool system, you can probably get a stat at Sears or HD or Lowes. You can also find 2 stage units.

I would go to the Honeywell site and search. You can access owner's manuals and see what their capabilities are.
