I have two M1KP LCD keypads in my house. One of the two shows the correct temperature. The other is reading about three degrees high. The ambient temperature has been measured by the HVAC service guy using an external sensor. Is there any way to calibrate the keypad that is reading high?
Press and hold the “*” key until the keypad goes into the addressing mode — screen should display “Exit when done F1 to set address” at which time you will need to press the **F2** key to adjust the Temperature Reading. After adjusting the Temperature press the Exit key twice to exit from programming
