An intelligent, advanced boiler control* ('abc
®
') continu-
ously monitors the boiler conditions, varying the heat
output to suit the system load. The control is able to
react to external "negative" influences in the rest of the
system (flow rates, air / gas supply problems) maintain-
ing boiler output for as long as possible without resorting
to a lock out condition. At worst the boiler will reduce
its output and/or shut down (shut off mode) awaiting
the "negative" conditions to return to normal before
re-starting.
The 'abc
®
' control cannot override the standard flame
safety controls.
