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).
