General features.
ZEUS Superior kW is a wall-mounted fan assisted generator
with sealed chamber (type C) for the heating and production
of domestic hot water with storage tank.
e boiler is type approved for installation outside of the
building in a partially protected place.
N.B.: A partially protected place is one in which the appliance
is not exposed to the direct action of the weather (rain, snow,
hail, etc..).
e boiler can also be installed in B
22
conguration using the
relevant kit (optional).
It is equipped with a stainless steel storage tank coil with total
capacity of 60 litres and a standard 2 litre domestic hot water
expansion vessel.
e ZEUS Superior kW series boilers are available with useful
heat output of 24 kW (20,640 kcal/h), 28 kW (24,080 kcal/h)
and 31.7 kW (27,250 kcal/h) with useful eciency exceeding
90%.
Adjustment and control are managed by an integrated P.C.B.
with microprocessor with continuous ame modulation by
means of two sensors (domestic hot water and heating).
e new electronics allow the connection of the appliance
to the CAR and to the Super CAR; both allow remote ma-
nagement and control of the boiler with extreme simplicity.
Moreover, the Super CAR allows the display of the relative
humidity of the room and the envisioned weather.
Using the Super CAR it is possible to indierently change
some settings of the boiler control panel and the Super CAR
control panel, such as: Summer Winter selection, domestic
water set-point, domestic water comfort status, Reset.
e boiler has a standard anti-freeze device that protects it to
a minimum temperature of -5°C (optional to -15°C).
e hydraulic circuit is provided with a copper water-
gas heat exchanger, which is characterised for the high
circulation available in the primary circuit and uses the new
hydraulic unit in composite material.
e circulation pump, the electric three-way valve and the
hydraulic circuit control devices are housed on this unit
(absolute system pressure switch, 3 bar safety valve, system
adjustable by-pass, etc...).
e intake of combustion air inside the sealed chamber and
the discarge of ue are ensured by a fan, ues functioning is
contolled by ow meter.
e boiler operating parameters are set using the buttons and
knobs while the status display, the functioning mode and the
malfunctions, takes place using a back-lit digital display.
