For example, when the “
I” key is pressed
on the Boiler Control until “bt” is displayed,
it will then flash a three digit number (such
as “0”) followed by either “F” (or “C”). This

Please note that in operating mode to hold the
display on the value the user can press and
hold either the Up ñ or Down ò keys and the
value will be continuously shown. This may be
helpful in watching a value “live”.
