The microCombi offers advantages to both the end-user and the
installer. The size and weight is clearly an asset of this
combination boiler.
Ariston have applied a lot of time and effort into the resear ch
and development of the standard features of the boiler. These
features include: electronic ignition, temperature control of both
the heating system and domestic hot water to an accuracy of ±
1
o
C, a "twin pass" heat exchanger (generating both domestic
hot water and central heating directly) and adjustable
independent hot water temperature regulation.
The microCombi is able to regulate the maximum heating output
via the printed circuit board. The boiler also features a soft
ignition function, therefor
e reducing the noise output when the
boiler star ts to work. In order to avoid potential problems, the
boiler features electronically controlled overheating protection, a
warning light for defective flue dischar ge, an anti-scale device
and anti-frost device.
