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.

The IQ Boiler Control is located inside the boiler
front door, just above the IQ Option Panel (Figure
8-a).
The IQ Boiler Control display, along with Up ñ,
Down ò, and “ I ” keys may be used to view boiler
operating status (Figure 8-b). Please note that
these keys look similar to the keys on the IQ
Option Panel but are in a different orientation, and
they perform different functions.
