6WDQGDUG GHVFULSWLRQ floor-standing condensing
gas boiler, for hot water heating, with a B
23
type ex-
haust circuit with linearly modulated power, and a
premixed burner with an air-gas servo-control sys-
tem, according to PR EN 676 (03/98).
The THR 10-100 boiler is the association of two
50 kW modules (10 to 50 kW linearly modulated
power) placed in a cascade in the same casing. The
RVA box manages the cascade function and deter-
mines the flow temperature settings for each modu-
le. The LGM box (module management box)
controls these two modules according to the tem-
perature setting.
It is preset with natural gas H.
According to the selected options, the THR 10-100
has a very extensive control potential:
- from simple network control to multicircuit man-
agement,
- possible direct domestic hot water production on
one of the modules or on the network.
