    I need to change my carrier infinity control thermostat from celsuis to fahrenheit?
    I know there is a button or something on the thermostat that you can easily change the reading from Celsius to Fahrenheit.
    I have read the manual and cannot find the answer.

    Does your thermostat look like the photo? If so, this procedure might help. You need to get into the service menus, which are normally hidden.

    1. Flip down the door at the bottom of the thermostat
    2. Press the Advanced setup button for at least 10 seconds
    3. You should now see the Install/Service menu
    4. Press the Scroll Down button until you get to Setup
    5. Press Select (right-side button)
    6. Highlight Thermostat and press Select
    7. Scroll down to English/Metric Display
    8. Highlight Fahrenheit and press Select
    9. Now keep pressing Back until you are back at the Install/Service menu
    10. Press Exit

    Don't stray from these steps because you can really mess things up if you change the wrong settings!

    I hope this helps,

    Hi
    I got to #7 and #8 in your instructions and when I press the button, it blinks C I cannot get it to change to F.
    Any more suggestions.
    Thanks Cory

    If you press the Scroll Down button it does not change to F? It sounds like you are so close!

    Good luck,

    Hi WallyH
    You asked "If you press the Scroll Down button it does not change to F? It sounds like you are so close!"
    When I get to this stage and press the Scroll Down button is just stays on C.

    Maybe I missed a step around step 7.

    Once you get to English/Metric, press Select. Then scroll to Fahrenheit and press Select again.

    I hope this was the missing piece!

    Hi WallyH
    Thanks for all your help. When I scroll, I still do not have a Fahrenheit to press Select for.
    Maybe my thermostat is Metric only, but I cannot believe that if they are sold in the USA, they are not Metric.
    Thanks again,
    Cory

    When you get to the C mark toggle the temp up and down button, that should change from c to f. press advanced and it asks you if you want to save chages, say yes and hit advanced again and it will take you back to normal screen.
