The
boiler will now
operate automatically to
provide
central
heating
for the conditions
selected on the external
con-
trols
(turboMAX
plus
will also
provide
domestic hot
water
on
demand). Whilst the boiler is
operating, the
boiler
display
(fiq.
B.2) indicates
the temperature of
the
water
within
the boiler
circuit. After the boiler stops
operating
the
pump
and fan will continue
to operate for
a short
period
to fully disperse
the
heat from
the boiler.
----=
The
boiler
incorporates
an anti-cycling
economi-
u
ser contro!
to
prevent
energy wasteful ON and
OFF operation
of the boiler
for
short
periods
when
in the
central heating mode. When
turning
the room
thermostat to a higher
setting there
may
therefore
be a short delay
before the boiler
operates.
