For example, when the “I” key is pressed on the IQ Boiler Control until “bt” is displayed, it will then flash a three digit number (such as “180”) followed by either “F” (or “C”). This indicates that the boiler water temperature is 180°F. Other operating parameters display the information in a similar fashion.
