It is distinguished by its compact size (H=780 mm, W=450
mm, D=250 mm), has an heat output of 23.3 kW (20,000
kcal/h).
A microprocessor controlled electronic board adjusts and
controls the appliance (burner ignition, temperature adjustment,
flame modulation and diagnostics) and the operating parameters
can be displayed and set by means of a digital interface with
display and push buttons.
General features.
e hydraulic circuit is equipped with a copper bithermal type
water-gas exchanger for the production of hot water for central
