The ANZ units are available in
versions equipped with supplementary
heaters; these versions are identified
by the letters K and J. Both versions
are equipped with a circulation pump,
an accumulation tank and a control
system that manages the supplementary
heater. The supplementary heaters are
housed within the accumulation tank for the units from size 0507 up to 2007;
for the remaining units, the relative
accessory (supplied separately) is to
be installed externally, at the expense
of the user. The running of the heater
is given over to an integrated control,
on the basis of the temperature of the
water and the outside temperature. In
the AK versions, a basic control is used, and this switches on the heater when
requested by the control logic. The AJ
versions are supplied with an advanced
control which, apart from enabling the
supplementary heater on the basis of
the outside temperature, can operate
a three-way valve (not supplied) for
applications with radiant panels.
(1) for these models, the heater is not supplied, but is available as an accessory
