OPERATION
Warmstart operation (TURBOmax
Plus only)
The warmstart facility provides
instantaneous delivery of domestic
hot water from the TURBOmax Plus
boiler.
When the warmstart system is
switched ON the boiler will
automatically light periodically to
maintain the internal temperature of
the boiler at approximately 40 °C.
When the warmstart system is
switched OFF a short delay may be
experienced in obtaining hot water at
the tap.
The warmstart system is activated
by turning the hot water tempera-
ture control knob (1) all the way to
the very right for a short time.
The green indicator light will now
illuminate. Reset the hot water
temperature control knob to the
desired setting. The boiler will now
provide instantaneous delivery
of hot water directly when a hot
water tap is turned ON.
The warm start system is switched
OFF by turning the hot water
temperature control knob (1) all the
way to the very left for a short
time. The green indicator light is
NOT illuminated. Reset the hot
water temperature control knob to
the desired setting.
Note:
Irrespective of whether the warm-
start facility is switched ON or
OFF, the boiler will automatically
operate to provide hot water
whenever a hot water tap is
opened.
