For example, when the “

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 Intelligent Hydronic Control (control) is located
inside the boiler front door, just above the IQ
Option Panel (Figure 8-a).
The 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.
